How to Use the FIFISH PRO W6

1. Pre-Dive Setup
2. Before launching, ensure the ROV battery is fully charged and the tether is securely connected. Power on both the ROV and the remote controller, then run a quick system check to confirm lights, thrusters, and camera are working properly. This step prevents mid-dive surprises and ensures a smooth start.
3. Tether Deployment
4. Unwind the tether slowly and keep it tangle-free while lowering the ROV into the water. Always ensure that the tether reel is secured on land or on the vessel so that the cable moves freely without strain. Smooth tether handling is key to stable underwater navigation.
5. Controller Operation
6. Use the controller’s joysticks to move in six degrees of freedom — forward, backward, up, down, sideways, and rotation. Switch on Posture Lock or Hover Mode when you need extra stability for precise inspections or filming. Practice short maneuvers before heading deeper.
7. Lighting and Camera Control
8. Adjust the LED brightness levels depending on visibility. Use low light in clear water to save power or full brightness in murky environments. Switch between photo and video modes as needed, and make use of RAW format for professional post-processing.
9. Post-Dive Routine
10. After completing the dive, slowly retrieve the ROV using the tether, rinse it in fresh water (especially after saltwater use), and carefully dry it before storage. Always back up your captured media from the storage card immediately.

How to Clean the FIFISH PRO W6
