: Paul, Julie's GPS bag she mentioned can allow the GPS to be operated while
: inside the bag, I think. But it is expensive and I am always looking for
: cheap. Zip Lock bags with air in them so they float might be make it
: difficult to punch the GPS buttons. Looking at Julie's bag, it looks like
: you could put foam strips for floation on the inside ends of the first zip
: bag, put you GPS in it and zip it up without any air. Put that bag inside
: a second bag and again zip it up without air inside so the buttons could
: be easily depressed and it would still float because of the foam strips
: inside.

I guess this calls for a bit of explanation of the technique involved.

The foam you mention is unnecessary. Its only virtue is that it has air trapped in the bubbles and cells it is made of. Putting it inside a bag that has even MORE air, is irrelevant. So. you can safely ignore the foam. Just shove the GPS into one bag, and neither suck all the air out, nor puff additional air in, and you'll have no problem working the pushbuttons on the GPS.

Do the same with the second bag. Add no additional air, and don't try to create a vaccuum.

A few moments of experimentation will get you there.

Hope this helps
