3. Notice of Measurements
- Short press the Mode button (?️) to switch modes.
- If the target reflection is weak or the target is out of measurement range during the measurement process, it will display as "---".
*The measurement range will be affected by factors such as the target material, the angle of the target surface, and weather visibility. Generally, if the target surface is smooth, bright, and has a large area, the measurement beam is perpendicular to the target surface, and the weather is cloudy without fog, the measurement range will be farther.
Ranging Modes
Short press the Mode button (?️) to switch between LOS mode, HD mode, and ARCH mode.
LOS Ranging Mode
Short press the Mode button (?️) to switch to LOS mode, aim at a point (within the measurement range), and then short press the Meas button (?️). LOS Ranging Mode refers to measuring the distance from the IONJET 2 to the target point, displayed in the first row on the measurement interface. (Diagram description: An illustration of a hunter aiming the rangefinder at a deer. A dashed line shows the Line of Sight (LOS) distance measurement, labeled "135.3Y", from the device to the deer. The display shows relevant icons.) The maximum range for LOS Ranging Mode is 2000 yards.
HD Ranging Mode
Short press the Mode button (?️) to switch to HD mode (triangle symbol), aim at a point (within the measurement range), and then short press the Meas button (?️). HD Ranging Mode calculates the horizontal distance from the IONJET 2 to the target point based on the distance measured by the IONJET 2 and the elevation angle. The first row displays the distance from the IONJET 2 to the target, the second row shows the angle between the IONJET 2 and the target, and the third row indicates the horizontal distance between the IONJET 2 and the target. (Diagram description: An illustration similar to the LOS mode, but showing a line-of-sight distance of "136Y" and a horizontal distance of "120Y" with an angle of "28°". The display shows HD mode icons.) The maximum range for HD Ranging Mode is 2000 yards, with an angle range of ±90°.
ARCH Ranging Mode
ARCH Ranging Mode is used to compensate for extreme vertical angles in archery. It requires knowledge of your arrow's speed, with the initial default speed set at 220 fps.
*You can adjust the fps setting in the menu, ranging from 200 to 350 fps. To set the fps: In ARCH function mode, long press the Mode button (?️) to enter the settings menu. The first menu is for setting the fps. Short press the Meas button (?️) to adjust the fps, increasing by 10 fps each time you press, within the range of 200 to 350 fps.
(Diagram description: Shows the display with "SPEED" and "220" fps.)
Short press the Mode button (?️) to switch to ARCH mode (arrow symbol), aim at a point (within the measurement range), and then short press the Meas button (?️), and the IONJET 2 will provide a solution as an equivalent horizontal shooting distance. The first row displays the distance from the IONJET 2 to the target, the second row shows the angle between the IONJET 2 and the target, and the third row shows the bow's compensation value.
(Diagram description: An illustration showing an archer in a tree stand aiming. The diagram displays distances "69.3Y" and "66.7Y", an angle "-30°", and a calculated shooting distance "80Y".)
Due to the physical limitations of arrow range, beyond 200 yards, the device will revert to the LOS distance to the target. The angle range is ±90°.
Settings
Entering Settings
After powering on, long press the Mode button (?️) for 2 seconds to enter the settings.
In *non-ARCH Ranging Mode, short press the Mode button (?️) to cycle between the three menus: target mode, unit switching, and brightness levels. Short press the Meas button (?️) to switch between the sub-options of these three menus.
*In ARCH Ranging Mode, there is an additional FPS setting function. Short pressing the Mode button (?️) will cycle between four settings: FPS setting, target mode, unit switching, and brightness levels. Other settings are the same as described below.
Exiting Settings
Long press the Mode button (?️) for 2s to exit the Settings mode.
Target Modes
The IONJET 2 has 4 target modes, with default mode being the Best Mode. To switch target modes, long press the Mode button (?️) to enter the target mode settings, and short press the Meas button (?️) to select the mode you want.
1. Best Mode:
This mode is recommended when there are no obvious obstructions in front of the target and no significant interference from the background. It offers a measure range up to 2,000 yards for most targets, which under normal ranging conditions have medium reflectivity.
- Short press Meas: Measures once and displays data related to the most reliable target.
- Long press Meas: Continuously measures and updates the display with each measurement result.
(Diagram description: Shows the display indicating "BEST" mode.)
2. Auto Mode:
This mode can measure the distances to both the nearest and the farthest targets simultaneously.
- Short press Meas: Measures once and checks if multiple targets exist. If they exist, the measurement results will blink alternately at 1-second intervals, displaying the data related to the nearest and farthest targets. If there are no multiple targets, only the measurement data for the nearest target will be displayed.
- Long press Meas: Continuously detects if multiple targets exist. After releasing the measurement button, the results will blink alternately at 1-second intervals, displaying the data related to the nearest and farthest targets. If there are no multiple targets, only the measurement result for the nearest target will be displayed. The blinking display effect is shown below. (Diagram description: Shows two display examples indicating "AUTO" mode with blinking results for nearest and farthest targets.)
3. First Mode:
This mode allows for easily obtaining distances to small targets and game animals without accidentally getting the distance to background targets, as the background targets have a stronger signal. When locking onto multiple targets, only the distance to the nearest target will be displayed. In this mode, align the reticle with the target you want to measure (e.g., a deer). Then, press and hold the Meas button (?️) and gradually move the reticle through the target (deer). If the laser beam locks onto multiple targets (deer and background trees), the screen will display the distance to the nearest target (deer) to you.
- Short press Meas: Measures once and outputs the measurement data related to the nearest target.
- Long press Meas: Continuously measures and updates the distance to the nearest target.
(Diagram description: Shows the display indicating "FIRST" mode.)
- Illustration: "Initial range captured on trees."
- Illustration: "Range captured on closer elk."
- Illustration: "Scanned to further trees. Range remains locked on closer elk."
4. Last Mode:
This mode is designed to ignore objects like shrubs and branches, displaying only the distance to the target. When multiple targets are locked, only the distance to the farthest target will be displayed. In this mode, align the reticle with the target you want to measure. Then, press and hold the Meas button (?️) and gradually move the reticle across the target. If the laser beam identifies multiple objects (branches up close and a deer in the background), the distance to the farther object (deer) will be displayed.
- Short press Meas: Measures once and outputs the measurement data related to the farthest target.
- Long press Meas: Continuously measures and updates the distance to the farthest target.
(Diagram description: Shows the display indicating "LAST" mode.)
- Illustration: "Initial range captured on trees."
- Illustration: "Range captured on farther elk."
- Illustration: "Scanned to closer trees. Range remains locked on farther elk."
