No need to put a GPS Marine Radio in a waterproof canister. the Nautilus Lifeline is so tough it is depth rated to 425 ft all on its own and its distress range is up to 3500 sq miles!
That is a VHF radio and is only good for line of site transmission. Transmitting from about 6" above the water I do not think it will cover 4 sq miles, never mind 3500 sq miles! How do you justify this claim?
