It would be handy on like a boat ramp that is short in deep water and it warns you of trailer falling off end if ramp under water.....and in Lake Michigan when at beach to drive on shore instead of waves pounding it.....i can think of alot of good uses for this
I agree, I can see a lot of uses for it, be pretty nice to have on some of the more remote rivers for outfitters and such, that make camp and set up as they travel!
or even in places with high and low tides to get to shore and not have to be tied off so far off into the water lines!
like anything, some will find it usefull and others will think its a joke !
all comes down to your intended use
I think its cool too!
however, I imagine its not cheap LOL
special boat set up and then trailer
but again, can sure see some good uses for it!
