Query: Waterproof? Up to a point.

The international standards of what is 'Waterproof' are a bit loose I think. This is actually OK if you immerse it up to about 1m deep for less than 30 seconds at a time. More water than than, and the so called waterproofing, is not so much.So, when you flip the catamaran several times in an afternoon, and take up to 15 mins to pull it upright again each time. this unit will not survive. You have been warned.However, if you are not planning to get it more than splashed with a few waves over it, or a bit of rain, or the odd straight turnover in a kayak, it should be fine.Until it got wet, it worked great and they found lots of fish with it.
