Learn how to attach your SeaLife Micro-Series or ReefMaster RM-4K camera to GoPro mounts and Flex-Connect accessories with the Action Camera Mount adapter.
Quick Answer
To use the SeaLife Action Camera Mount, screw the adapter into your camera's 1/4-20 tripod mount, then attach it to any GoPro mount or Flex-Connect accessory using a GoPro thumb knob and bolt.
Why This Adapter Matters
The SeaLife Action Camera Mount bridges the gap between SeaLife cameras and the vast ecosystem of GoPro mounts and accessories. This is especially useful if you already own GoPro gear or want to expand your mounting options without buying a new tray.
Because the adapter works with any camera that has a standard 1/4-20 tripod mount, it also opens up possibilities for other devices, not just SeaLife cameras. However, you'll need a GoPro thumb knob and bolt to complete the connection—these are not included with the adapter.
Compatibility and Limitations
This mount is designed for Micro-Series and ReefMaster RM-4K cameras, but it can also be used with any camera that has a standard 1/4-20 tripod mount. That said, it does not work with cameras that lack a tripod thread, so check your camera's base before purchasing.
Another limitation: the adapter only provides a mounting point—it does not include a tray or arm. For a complete underwater rig, you'll need to pair it with a Flex-Connect arm or tray system.
Step-by-Step Setup Guide
- Screw the adapter into your camera: Align the adapter's 1/4-20 screw with your camera's tripod mount and turn it clockwise until snug. Do not overtighten—finger-tight is enough to avoid stripping the threads. Check the adapter is seated flat against the camera base before tightening.
- Attach the GoPro thumb knob and bolt: Insert the GoPro thumb knob and bolt through the adapter's slot and into your GoPro mount or accessory. Tighten the knob until the camera is secure but still adjustable. Make sure the bolt is fully threaded before applying pressure—partial threading can cause the camera to drop.
- Connect to your Flex-Connect arm or tray: If using a Flex-Connect arm, attach the GoPro mount (e.g., a GoPro adapter) to the arm's ball joint. Then connect your camera assembly to the mount. Ensure the ball joint is tightened enough to hold the camera in position underwater. Test the setup by moving the arm gently to confirm the camera stays put; re-tighten if there is any play.
