Yamaha Seascooter RDS300 Camera Mount

We're avid boaters regularly spending days on the hook enjoying sun, sand, and water. Bought this with the hope that the kids and I could use it to more easily explore nature underwater. Unfortunately it won't pull me, and barely pulls the kids. It's so bad that in first use I thought the battery must have not fully charged or something must be amiss. But after ensuring full charge and everything properly seated, and testing on multiple occasions I can undoubtedly tell you this is nothing but junk. Very disappointing for how expensive it is and how much tedious prep and breakdown labor is required each time you want to use it. Would have been willing to overlook how much space it consumes being stored on the boat, or the work to disassemble and reassemble everytime you use it (battery must be pulled out every single time to charge requiring you to break down the entire top half of the unit which must also occur everytime you finish using (in salt water) to rinse it) if it actually did what they claim it would. But it simply does not perform. If you can't resist the thought of wanting to feel like James Bond or a Navy Seal, effortlessly streaming underwater to your next mission, be forewarned - not going to happen with this piece of junk.
