3. Setup and Installation
The HURRICANE HUR 91A fish ruler is designed for permanent or semi-permanent installation to ensure stability and consistent measurements.
Installation Steps:
- Choose Location: Select a flat, stable surface on your boat deck, cleaning station, or wall where the ruler can be securely mounted and easily accessed. Ensure the chosen location allows for the full 40-inch length of the ruler to be utilized.
- Position Ruler: Place the L-shaped end of the ruler against a vertical surface or edge, ensuring the measuring surface is horizontal and level.
- Mark Holes: Use the pre-drilled holes on the L-shaped end as a template to mark the drilling points on your chosen surface.
- Drill Pilot Holes: Drill pilot holes appropriate for your chosen mounting hardware (screws, bolts, etc.). Ensure the pilot holes are slightly smaller than the hardware to provide a secure fit.
- Secure Ruler: Attach the ruler using corrosion-resistant screws or bolts (not included) through the pre-drilled holes. Tighten securely, but do not overtighten, to prevent damage to the ruler or mounting surface.
Note: For marine environments, use stainless steel hardware to prevent rust and corrosion.
4. Operating Instructions
Using the HURRICANE HUR 91A fish ruler is straightforward. Follow these steps for accurate fish measurement:
- Prepare Fish: Ensure the fish is calm and positioned safely.
- Position Fish: Place the fish on the ruler with its mouth or snout firmly against the L-shaped end (the zero point of the measurement).
- Straighten Fish: Gently straighten the fish's body and tail to ensure it lies flat along the ruler. For fish with forked tails, measure to the fork. For fish with rounded or square tails, measure to the tip of the tail.
- Read Measurement: Read the measurement at the furthest point of the fish's tail. The ruler is marked in 1/4 inch increments for precise readings.
- Record and Release/Keep: Record the measurement as required by local regulations. Handle the fish carefully if releasing.
Important: Always consult local fishing regulations for specific measurement requirements and legal lengths for different species.
5. Care and Maintenance
Proper care will ensure the longevity and accuracy of your aluminum fish ruler.
- Cleaning: After each use, rinse the ruler with fresh water to remove fish slime, salt, and debris. Use a mild soap and soft brush if necessary.
- Drying: Dry the ruler thoroughly with a cloth to prevent water spots and maintain its appearance.
- Storage: If not permanently mounted, store the ruler in a dry place away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect the ruler for any signs of damage, bending, or wear that could affect its accuracy.
6. Troubleshooting
If you encounter issues with your HURRICANE HUR 91A fish ruler, consider the following:
- Inaccurate Measurements:
- Ensure the fish's mouth/snout is firmly against the L-shaped end.
- Verify the fish's body and tail are straightened along the ruler.
- Check the ruler for any physical damage (bends, dents) that might distort measurements.
- Confirm the ruler is securely mounted and not shifting during use.
- Fading Markings: While designed for durability, prolonged exposure to harsh elements can affect markings. Regular cleaning and proper storage can help preserve visibility.
