I was just thinking after reading other posts that claimed the remotes for the ultrex motors are waterproof that if one had the remote on a strap around the neck and happened to fall out of the boat, it could provide a way to bring the boat back to oneself while in the drink. Would be especially important if the constant on mode was in use. Not quite sure how far the range is for Bluetooth reception but would think it might have the distance capabilities to get the boat back and positioned so one could climb back inside for drip drying. Just one more reason to justify to SWMBO why an Ultrex is a need, not a want. What y'all think?
