Clearly one of the goals is to be able to claim "Waterproof" by the marketing department. In my opinion, we tend to stress the products more than other users because they sit on a hot kayak deck, easily reaching over 100F (in my case) then being immersed in water that may be 40 degrees cooler. That change in temperature, causes a change in pressure and results in equivalent depths many times greater than the 5 feet stipulated in the specs. If you have a look at the construction of a scuba computer, the battery compartment is oring sealed and screwed shut. The electronics are typically encapsulated in a special potting mixture. All exposed metal (contacts, etc) is stainless. The big difference is that computers do not need regular battery changes like GPS units do. So, for me, when I need to use a GPS in the bath (not too hot) I'll forgo a case. When I need to use it in real world conditions, I'll give it the extra protection it requires. cu *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
