Ignore the water ratings, put your GPS in a bag!

I called Garmin to ask about the new 76CS which has a submersible rating for 30 minutes. The submersible rating is if you put the unit in a bucket and let it sit there undisturbed. It does NOT cover water spray, and Garmin told me they do not recommend using the unit unprotected in rain conditions (they say rain can reach 60 mph) or other high spray conditions (a.k.a catamaran sailing).
