Battery Information
Basic Information
- Battery Type: Internal Lithium-Ion
- Battery Life: 16 hrs typical, depending on settings
- Battery Scale: 25% per pixel, bottom pixel flashes at 5% remaining
- Recharge Time: 7 to 8 hours from supplied 3-amp USB wall charger or comparable USB port (with detector OFF, longer if ON). Charge times will increase with lower-rated chargers.
- Charging Status: Flashing while charging, solid when charged
- Battery Life Cycle: Batteries will last for many years. Recharge at least once a year.
- Charging Note: Detector should be switched off during charging to speed the charging process. Use a 5V USB-C power source that can provide 3 amps to achieve the fastest charge time.
Note on Battery Life Cycle: To extend the life of your detector's internal battery, it should be charged prior to storage for extended periods and recharged at least once per year. It is not necessary to fully discharge the Axiom battery prior to charging.
In the event of premature battery failure, the battery can be replaced at any certified Garrett service center.
Axiom Booster Pack
In the event of a depleted battery, Axiom can be operated with a booster pack, when needed. Expect 6 to 8 hours of operation.
- Power the booster pack with eight (8) AA alkaline or NiMh batteries. Note the proper direction for inserting each battery. This pack will not recharge the Axiom internal battery and is only functional when the Axiom's internal battery is completely discharged.
- Clip the pack into the stand below the cuff; it clicks into place.
- Plug in the USB connector.
The USB-C charging port is located under a weatherproof rubber flap on the back of Axiom.
Detecting / Recharging with other USB Power Bank
A standard 5-volt USB power bank can be used to power the Axiom and/or to recharge its internal battery. A power bank with a 3-amp capacity will provide the fastest charge.
Charging From 12V Battery Terminals (optional)
Attach the black negative (-) clip to the negative (-) battery terminal, and the red positive (+) clip to the positive (+) battery terminal. Plug the charging connector into the USB-C port on the rear of the Axiom. Charge time is approximately 10 hours.
Z-Lynk Wireless Operation
Axiom features a built-in Z-Lynk wireless transmitter which can be used with Garrett MS-3 wireless headphones and any Z-Lynk enabled devices. A Z-Lynk Wireless headphone icon on the LCD indicates the current status of your wireless connection. A steady icon indicates pairing and range; a flashing icon indicates searching for a receiver; absence of the icon indicates the transmitter is off.
Pairing:
To pair with new headphones/receiver, switch the headphone/receiver on, hold within 2 feet (0.6 meters) of the Axiom. Power on Axiom. Repeatedly press the MENU button until the wireless icon is highlighted. Press the (+) button to pair.
Once paired, if the headphone/receiver is switched off or moved out of range, Axiom will search and attempt to reconnect for 5 minutes (indicated by a flashing icon). If not reestablished, Axiom will switch off its wireless transmitter. To reconnect, switch the Axiom off and then on again.
Unpairing:
To unpair (forget) headphones, press the MENU button to select the wireless icon and then use the (-) button to unpair.
Use of optional wired headphones:
Axiom can also be operated with any wired headphones that have a 1/4" plug. For headphones with an 1/8" plug, an optional adaptor is available from Garrett.
Note: Packages shipped with MS-3 headphones include a user's guide for full details on wireless headphone operation.
Functions and Settings
Your Axiom is a highly sensitive pulse induction detector engineered for ease of operation. Each of its specific settings and functions are fully described in the following pages.
Factory Reset
Any changes made to Axiom settings are saved when the unit is switched off. To return all settings back to the original Factory values, press and hold the Power button for five (5) seconds. Axiom will produce a double beep to indicate that Factory Reset is complete.
Frequency Scan
Use this function to obtain the quietest operating frequency. Audio responses can become erratic due to electromagnetic interference (EMI) from sources like power lines, other detectors, or indoors. To check for EMI, hold the Axiom searchcoil stationary away from any metal. If the detector remains noisy, it is caused by EMI.
To perform a Frequency Scan:
- Hold searchcoil stationary away from any metal.
- Press MENU button until FREQ SCAN is highlighted.
- Use the MENU plus (+) button to begin process. Axiom will scan through 100 frequencies, recheck the best 5, and then automatically pick the best frequency.
- Takes approximately 45 seconds.
Note: If you accidentally activate Frequency Scan and wish to exit, press the Minus (-) button. The setting will return to its previous value.
Detection Modes
The Axiom has four Search Mode options: Fine, Normal, Large, and Salt. Each is optimized for specific types of detecting. The Factory Default mode is Fine.
Press MENU button until MODE is selected, then use the Menu Plus (+) or (-) button to select the desired mode. Press Operate to exit the MENU, or press MENU to proceed to the next menu item.
- FINE Mode: Provides maximum detection on small, low-conductivity targets (like fine gold and specimen gold), and good detection of medium/large targets. It can be more susceptible to ground minerals, hot rocks, or saltwater due to its increased sensitivity. FINE is typically preferred for most conditions.
- NORMAL Mode: Provides very good detection on all size targets. It is less reactive in highly mineralized soil but has reduced detection of very small targets.
- LARGE Mode: Maintains strong detection of large targets while reducing small and medium targets. It reduces susceptibility to highly mineralized ground and hot rocks.
- SALT Mode: Designed for use in mineralized areas with wet salt content, primarily for wet saltwater beaches. It may also be useful for dry inland salt lakes and goldfields with high salt concentration. It is recommended to try other modes first for inland conditions.
Volume and Threshold Adjustment
Volume Control
Use the Volume Plus (+) or Minus (-) buttons to adjust the maximum audio level produced by a large signal. This does not affect the audio level or sensitivity of a faint signal; Volume acts as a "limiter". Axiom Volume is adjustable between 0 (no audio output) and 24. The default setting is 24.
Threshold
Use the Threshold Plus (+) or Minus (-) buttons to adjust the constant audio background "hum" added to the target response. Axiom Threshold is adjustable between -9 and 25. The default setting is 15.
It is recommended the Threshold be set to a barely audible level, or just below, based on hearing ability and surrounding audio conditions. Running with a high Threshold level may obscure faint signals. Setting the Threshold level too low may prevent faint signals from being heard. Readjust the audio Threshold level as conditions change (e.g., strong winds, surf noise) that affect your ability to hear the background hum.
Tone and Audio Options
The Axiom allows users to change the pitch of audio tones and select from two distinctly different audio types.
Tone Adjustment
Press the MENU button until TONE is selected, then press the MENU Plus (+) or Minus (-) buttons to scroll through 100 available tone shifts. Each shift is minor, allowing adjustment to a preferred tone. Note: TONE adjustment is only available when operating in VCO audio type (Audio 01).
Audio Type
Press the MENU button until AUDIO is selected, then press the MENU Plus (+) or Minus (-) buttons to select either Audio 00 (PWM audio) or Audio 01 (VCO audio). The default setting is Audio 01 (VCO).
In either audio type, the Axiom's continuous audio responds proportionately to the target's signal strength. Large/strong signals sound loud, and small/weak signals sound faint, enhancing the ability to judge a target's size, shape, and depth. Proportional audio also allows the operator to hear faint background noise. Some minor audio noise/chatter is normal for high-performance pulse detectors.
General Rule: Poor conductors (small nuggets, specimen gold, nickels, small bronze coins) produce a high tone followed by a low-tone echo. Good conductors (large nuggets, copper/silver coins) produce a low tone followed by a high-tone echo. A target on the borderline may fluctuate between high and low tones.
Iron Targets: Iron targets can vary widely in readings. Small iron is often a high tone, and large iron is often a low tone, but not always.
- Audio 00 (PWM Audio): Target's volume increases proportionally with signal strength, but audio pitch is fixed at either a high or low tone.
- Audio 01 (VCO Audio): Target's volume and audio pitch both increase proportionately with signal strength. Preferred by most users for its smooth response and ability to perceive faint targets.
Target Signal Strength Indicators
Detected targets are heard and shown on the Axiom. The upper bargraph shows signal strength and polarity. Targets with high tones create a proportional response toward the right; low-tone targets create a response toward the left.
Backlight, Speed, and Sensitivity
Backlight
Press MENU until the Backlight icon is selected, then press MENU Plus (+) or Minus (-) buttons to switch the LCD backlight on or off, for searching at night or in low-light situations. The backlight will automatically activate when scrolling through the menu and return to its selected setting once the menu is exited.
Speed
This adjustment refers to the coil scanning speed and target recovery speed (Reactivity). Set Speed according to your preferred scanning speed, recovery speed/reactivity, and EMI noise conditions.
Press MENU until SPEED is selected, then press MENU Plus (+) or Minus (-) buttons to choose between Slow, Medium, or Fast scan speeds.
- SLOW: Produces smoothest, quietest operation for excellent depth and sensitivity, but requires a slow coil swing and has less ability to separate adjacent targets due to slower reactivity.
- MED (Default): General-purpose selection for moderate coil swing speed. Provides increased ability to separate adjacent targets due to medium reactivity. May have increased EMI and noise chatter compared to SLOW, but still offers good depth and sensitivity.
- FAST: Allows faster coil swing to search areas more quickly and increased ability to separate adjacent targets due to faster reactivity. May increase EMI and noise chatter, making it harder to discern faint targets.
Sensitivity
Use the SENS Plus (+) or Minus (-) buttons to select one of eight (8) Sensitivity levels. Default setting is 6.
Use increased sensitivity for very small or very deep targets. Use lower sensitivity levels when the detector behaves erratically (due to excessive metallic trash, highly mineralized soils, electrical interference, or other metal detectors) and the erratic operation cannot be resolved with Ground Balance or Frequency Scan.
Note: The upper Sensitivity settings (7 & 8) are extremely sensitive and may not be stable for many users and conditions. These are designed for experienced users accustomed to operating detectors at the limits of marginal stability.
Ground Balance Procedure and Indicators
Ground mineralization can create erratic detector sounds ("ground noise") and reduce performance if not compensated for. Axiom has advanced Ground Balance capabilities for all ground conditions, including ironstone ground and saltwater.
Recommendation: Ground Balance the Axiom in each new environment to ensure maximum stability and depth.
Note: DD coils are inherently less susceptible to ground mineralization than mono coils, providing better stability and performance in severely mineralized grounds.
Ground Balance Procedure
- Find an area clear of metallic objects and raise the searchcoil about 6 inches (15 cm) above the ground.
- Press and hold the GND BAL button while bouncing the searchcoil from 1 to 6 inches above the ground.
- Continue pumping the coil until the ground response is completely eliminated or becomes as small as possible.
- Release the GND BAL button.
Ground Balance Values
The Axiom continually displays current ground balance values using two independent numbers. During the Ground Balance procedure, these numbers lock or stabilize at the best values. With Ground Track set to OFF, these numbers will not change until you either Ground Balance again or engage a Ground Tracking option.
Typical GB range by Ground/Target:
Ground/Target | Typical GB range (Upper and Lower numbers) |
---|---|
Saltwater | Upper: 0-15 Lower: 0-20 |
Moist salt bed / salty soil | Upper: 0-15 Lower: 0-20 |
Moist salt bed / salty soil mixed with ferrous ground, some hot rocks or terra cotta | Upper: 15-45 Lower: 10-20 |
Typical ferrous ground without salts, most hot rocks and terra cotta | Upper: 45-55 Lower: 20-35 |
Chunk of iron (e.g. large nail or spike) | Upper: 55-80 Lower: 30-60 |
Piece of non-ferrous metal (e.g. aluminum can) | Upper: 80-99 Lower: 60-99 |
Ground Balance Window
Axiom's Ground Balance Window feature helps overcome hot rocks and other localized ground variations. Hot rocks are typically highly ferrous, iron-based rocks that are either more or less conductive than the surrounding soil, creating a response that can resemble a target. Because of Axiom's immunity to most normal soil minerals, hot rocks can typically be eliminated by ground balancing to the hot rock instead of the ground. In extremely mineralized soil, the Axiom must be ground balanced to the soil, in which case the hot rock may produce a response.
To simultaneously eliminate the hot rock and mineralized soil, change the Ground Balance procedure: hold down the GND BAL button while combining a vertical pump over the soil with a horizontal scan across the hot rock in a repeating pattern. Pause briefly between the vertical pump and horizontal sweep to ensure distinct signals. Continue until ground and hot rock responses are eliminated or become as small as possible, then release the GND BAL button.
Ground Track
When switched on, Ground Track automatically adjusts ground balance values to track changes in ground mineralization. However, when entering a new area, perform Ground Balance first to obtain a good starting point.
Press the MENU button until GND TRACK is selected, then press the MENU Plus (+) or Minus (-) buttons to scroll through the four Ground Track settings: OFF, SLOW, MED, and FAST.
- OFF (Default): Ground Tracking is not activated; ground balance values remain fixed. Preferred unless tracking is needed for frequently changing ground conditions.
- SLOW: Ground balance values track slowly changing ground conditions very slowly.
- MED: Ground balance values track changes in ground conditions a little faster.
- FAST: Ground balance values track even faster for quickly changing ground conditions, but may produce the greatest loss in detection depth.
Note: Ground Track may reduce detection depth due to slow tracking, especially at faster settings. Use only as much tracking speed as necessary to keep ground responses suppressed. If Ground Track is ON but values remain constant, ground conditions may be stable enough to switch Ground Track OFF.
Ground Trend Arrows
When Ground Track is ON, arrows show the trending direction of the changing ground balance values.
Iron Check
Use this feature to audibly identify iron targets. Iron Check only works with DD searchcoils; it will not work with mono coils. Pressing the Iron Check button with a mono coil produces a repeating warning alarm.
To Utilize Iron Check:
- Move the searchcoil to the side of the target.
- Press and hold the IRON CHECK button and wait for a double-beep.
- Continue holding the IRON CHECK button while repeatedly scanning back and forth past the target with very flat, level swings.
- If desired, check the target again from different directions by rotating around 90 degrees. Maintain very flat, level swings.
- Iron will produce a very low-tone buzz sound that may or may not be flanked by normal tones.
- Non-ferrous and/or weak targets will produce normal tones, or may be silent, but typically won't produce the iron tone (buzz).
Note: Iron Check is conservative to avoid misidentifying good targets as iron. The iron tone (buzz) only activates on strong signals. Small/weak iron targets may not identify as iron. Steel bottle caps, due to their large surface area and high conductivity, typically will not identify as iron.
Examples of iron targets producing the iron tone (buzz): a 3-inch nail at ~5 inches depth; a 3/4-inch boot nail at ~2 inches depth. In highly mineralized areas, Iron Check accuracy may be affected; use flat, level swings for accuracy.
Detecting Techniques and Tips
If you are new to metal detecting, start in areas with sandy and loose soil to make it easier to learn how to use your detector, pinpoint targets, and recover them.
Adjust Stem Length and Coil Angle
Release lower stem clamp and fully extend until it snaps into place. Adjust upper stem to a comfortable length and close stem clamps. When properly adjusted, you should be able to swing the coil over the ground without stretching or stooping. Your searchcoil should remain parallel to the ground as you sweep it. The coil's bolt should not be overtightened; it should be tight enough to maintain angle but loose enough for easy adjustment.
Proper Coil Swinging
Keep your searchcoil height about 1½ inch (1.25cm) above and parallel to the ground at all times for best detection results. Walk slowly, scanning the searchcoil in a slight arc from side to side at a speed of about 3 feet (1 meter) per second. Advance the searchcoil about half the length of the searchcoil at the end of each sweep. Avoid excessive contact with rocks.
Operating with Short Stem Length
In some scenarios, like searching walls of mines, you may want to collapse the Axiom to a very compressed operating length. First, fully collapse the upper stem. Then, collapse the lower stem partially, leaving at least 10 inches (25 cm) exposed. This helps prevent the coil from detecting the stem clamp and other metal. Ensure the coil angle does not move to prevent false signals.
Pinpointing a Target
To precisely locate a target, sweep the coil side-to-side and front-to-back in a cross-hair pattern over the target area, listening for the peak audio signal beneath the center of the coil. For very small, shallow targets, use either front corner of the mono coil to more precisely locate the target.
Bench Tests
Conduct bench tests to become familiar with the Axiom's signals and operation using different Modes, Speeds, and Audio Types. Suggested test items include:
- Various size gold nuggets or gold rings. (Note: A U.S. nickel or small bronze coin can imitate the response characteristics of a similar size nugget.)
- Coins or relics expected to be found in your search area.
- Various size iron targets for testing the Iron Check feature.
Note: High-performance pulse detectors like the Axiom can be noisy indoors due to electromagnetic interference (EMI). It is best to test outdoors, away from common EMI sources (power lines, electrical equipment, buildings, etc.). Tests should be performed with the searchcoil stationary and several feet away from any large metallic object.
Basic Testing
Pass various metallic targets side-to-side across the bottom of the searchcoil, both near and far, to hear how proportional audio sounds (loud for strong signals, faint for weak signals).
Tone Polarity Test
Pass various metallic targets over the searchcoil using both Audio 00 (PWM audio) and Audio 01 (VCO audio). Poor conductors produce a high tone followed by a low-tone echo. Good conductors produce a low tone followed by a high-tone echo. A target on the borderline may fluctuate between high and low tones.
Iron targets can read everywhere on the tone/conductivity scale, affected by size, shape, orientation, and condition. Small iron is often a high tone, large iron often a low tone, but not always.
Iron Check Test
Iron Check only works with a DD searchcoil. Press and hold the IRON CHECK button for a double beep before scanning targets. Continue holding while scanning targets back and forth. Notice which iron targets produce the low-tone growl/grunt sound and at what distances. Notice how orientation changes response. Iron Check is conservative to avoid misidentifying good signals; small iron targets may not identify as iron.
Test ferrous and non-ferrous targets at various depths to understand Iron Check's capabilities and limitations.
Sensitivity Test
Increase and decrease Sensitivity to see how detection depth and noise are affected. Higher Sensitivity increases depth and possibly noise.
General Advice
Metal Detecting Code of Ethics
Many treasure hunters and clubs follow this Code of Ethics to preserve the sport:
- Respect private and public property, historical and archaeological sites; do not detect without permission.
- Keep informed on and obey all local and national legislation regarding treasure discovery and reporting.
- Aid law enforcement officials whenever possible.
- Cause no willful damage to property, including fences, signs, and buildings.
- Always fill the holes dug.
- Do not destroy property, buildings, or remains of deserted structures.
- Do not leave litter or discarded junk items lying around.
- Carry all rubbish and dug targets when leaving a search area.
- Observe the Golden Rule, using good outdoor manners and conducting yourself to add to the stature and public image of metal detection.
Cautions
When searching for treasure with your Garrett detector, observe these precautions:
- Never trespass or hunt on private property without permission.
- National and state parks/monuments and military zones are off-limits.
- Avoid areas with buried pipelines or electric lines. If found, do not disturb and notify proper authorities.
- Use reasonable caution when digging any target, especially if uncertain of conditions.
- If unsure about using your metal detector in any area, always seek permission from proper authorities.
Caring for Your Axiom
Your Garrett detector is rugged and designed for outdoor use. However, as with all electronic equipment, simple care maintains its high performance.
- Avoid extreme temperatures (e.g., storing in a hot car trunk or in sub-freezing weather).
- Keep your detector clean. Remove stems and wipe them, the control housing, and the searchcoil with a damp cloth.
- Remember the searchcoil is submersible, but the control housing and connectors are not.
- Recharge the detector's battery at least once a year if not used regularly.
Troubleshooting
SYMPTOM | SOLUTION |
---|---|
No power | 1. Ensure battery is charged. 2. Connect to charger and verify the battery icon is blinking (indicating charge in progress). |
Erratic sounds | 1. Ensure the coil connector is secure and the coil cable is snugly wound around the stem. 2. Perform a factory reset (hold Power button for 5 seconds). 3. If indoors, be aware of excessive electrical interference and metal in floors/walls. Move outdoors to an area clear of excessive metal, powerlines, etc. 4. Determine if noise is caused by EMI or something else. Hold the coil stationary on the ground away from any target. a. If noise continues (likely EMI): Perform Frequency Scan; Reduce sensitivity if needed. b. If noise stops (likely ground/metal detection): Ensure Axiom is properly ground balanced; Ensure no nearby/buried metal; Investigate remaining responses (deep/faint signals); Reduce sensitivity if needed. |
Intermittent Target Signals | Intermittent signals typically mean a deeply buried target or one positioned at a difficult angle. Scan from different directions to define the signal, and/or scrape away some soil to get the coil closer to the target. |
Responds when bumping coil against rocks, etc. | Use a coil cover to cushion the coil's impact with items such as rocks, trees, etc. |
