<div dir="ltr"><div><div>Joe, thanks for the feedback.<br><br>It is funny how posting an idea will all of a sudden opens your eyes to other solutions : )<br><br></div>Based on Alec's comment I can see that for my 4 hour operational requirement I could potentially just utilize the laptop or tablet's internal battery (maybe have to also use a spare battery) vs. the power suck of trying to generate 120V AC. This way I would only need to supply the sonar head and I could do this easily with a small AGM battery.<br>

I think the first thing I'd look at is whether one could interface the sonar to a tablet instead.
