I would like to second this question. I just got a Magellan Meridian. Looking it over I dont think it is really waterproof enough, my thought is to strap a waterproof bag (perhaps one made for a gps) to my wetsuit just above my knee. The thought being it would be hands free and close enough that I could read all the neccessary information(how fast I am going). Has anyone else rigged something like this? better ideas?
