Charlie,
On the Depth Finder, all you need to do is know is it’s current draw and the amp hour rating of your battery. example would be 500 mA (that’s .5 Amps) of current draw on a 100 Amp Hour battery (can supply 100 Amps for 1 hour) would equal 200 Hrs. I would imagine your finder draws maybe 100 mA (or less).
