My chief concern, believe it or not, is obstacle avoidance ...how good do you think the Interphase system is for that? I'm building a boat (
http://www.advantagecomposites.com/tongass ) that I will be outfitting with lots of fuel storage and an efficient motor ...expect to explore wild and wooly place between here, and in, SE Alaska. Since some locales may find me a long way from a dock, hitting deadheads is something I want to be prepared for. I've got a collision chamber going in, positive upright flotation going in, etcetera ...but would be highly interested in a system that lets me see obstacles before I 'find' them the hard way. I'll have a separate fish finder if I need to, but hmmmmmm....wonder how that Interphase system is for giving you adequate warning of floating debris?
Thanks,
Brian
