Was in McQueens last weekend with a guide. At some point I would like to get back to the area. Aside from the risks of entry to the area I am concerned with communication. Would a handheld 5W VHF communicate thru the island back to St Cats Sea Tow (or anyone else for that matter) for help. I know ranges for the handhelds are fairly good, but can this thing communicate back thru the island?
