They probably do have the 12 volt dc remote pack for it, but they probably charge a hundred and a half for it and call it the ice transducer kit! It's all about the $.
........................Another thing that I learned was that a 5” diagonal screen is just not enough. No where near enough.As a matter of fact, I doubt the largest 12” unit they sell is enough.Time to start building these things as a head unit that plugs into a 32” flat screen monitor.When I retire in a few years, and move to Florida and get my boat down there, it will for sure have whatever the largest screen available. That’s a fact.........................Mac
