The camera itself is not included with the weight.
Setup and Installation
The Aqua-Vu XD Trolling Auxiliary Weight is designed for quick and easy attachment to any Aqua-Vu XD underwater camera system.
Attaching the Auxiliary Weight
- Identify the XD Quick Attachment System: Locate the Quick Attachment slide system on the underside of your Aqua-Vu underwater camera. This system is designed to accept various XD accessories.
- Align the Weight: Position the Aqua-Vu XD Trolling Auxiliary Weight so that its attachment grooves align with the rails of the camera's Quick Attachment system.
- Slide and Secure: Gently slide the auxiliary weight onto the camera's attachment system until it clicks securely into place. Ensure it is firmly seated and does not wobble.
- Verify Connection: After attachment, lightly tug on the weight to confirm it is properly secured to the camera.
Note: The camera itself is not included with the auxiliary weight. This product is an add-on accessory.
Operating Instructions
Once the Aqua-Vu XD Trolling Auxiliary Weight is attached, your camera system is ready for enhanced trolling performance.
Using the Weight for Trolling
- Increased Depth: The added 14 ounces (approximately 400 grams) of weight will help your Aqua-Vu camera descend faster and reach greater depths more efficiently.
- Enhanced Stability: When trolling or moving your boat at higher speeds, the auxiliary weight provides increased stability, reducing camera movement and improving image clarity.
- Optimal Speed: Experiment with different trolling speeds to find the optimal balance between camera stability and desired depth. The weight is designed to maintain stability even at faster trolling speeds.
Maintenance
The Aqua-Vu XD Trolling Auxiliary Weight is constructed from durable materials designed for marine environments. Minimal maintenance is required.
- Rinse After Use: After each use in saltwater or murky freshwater, rinse the weight and camera attachment points with fresh water to remove salt, dirt, and debris.
- Inspect for Damage: Periodically inspect the weight and its attachment mechanism for any signs of wear, corrosion, or damage. Ensure the sliding mechanism operates smoothly.
- Storage: Store the auxiliary weight in a dry, cool place when not in use.
Troubleshooting
If you encounter any issues while using your Aqua-Vu XD Trolling Auxiliary Weight, consider the following:
- Weight Not Attaching Securely:
- Ensure the camera's XD Quick Attachment system and the weight's grooves are clean and free of debris.
- Verify that you are aligning the weight correctly with the camera's attachment rails.
- Apply gentle, even pressure when sliding the weight into place until it locks.
- Camera Still Unstable During Trolling:
- Confirm the auxiliary weight is securely attached.
- Reduce trolling speed if necessary.
- Check for strong underwater currents that might be affecting camera stability.
- Weight Not Sinking Fast Enough:
- Ensure no other buoyant accessories are attached to the camera that might counteract the weight.
- Consider the density of the water (saltwater is more buoyant than freshwater).
