Fixed VHF radio (starting at under 100 bucks)
Handheld VHF (for use in the cockpit and redundancy. About 100 bucks)
I've been sailing for 2 years with 2 depthfinders. I didn't realise it was so important to have a fishfinder while sailing that I should have a backup as well as a main fishfinder... good grief, I shudder when I think of the risk I've been taking, not having a working fishfinder....
