Home Forums Fishing Freshwater Best sub-$200 fish finder for ice fishing?

Ok, the family bought me a Garmin striker 4 plus. Just the basic unit, not the ice fishing kit. I didn't drop any hints, not sure how they decided.

So I'm going to need a battery, case, etc. I like the idea of using an 18v power tool battery since I'm using a Ridgid drill to spin the auger. The Garmin unit can handle from 10v - 20v input voltage. Max current is 1amp, likely when running at minimum voltage.

I'm not sure what sort case to put everything into.

The fun starts!

I'm going to try the following battery -

And connect it using - https://www.amazon.com/gp/aw/d/B091...wmYWN0aW9uPWNsaWNrUmVkaXJlY3Q=p13NParams

I'm sure the cheap China battery will work for the Garmin Striker 4 Plus and hopefully it will work for my 1/2" drill as well. I'm guessing that the 2.0AH oem battery that came with the drill will power the Garmin for the 6-7hrs of ice fishing, but this way I'll have an extra battery to run the auger. I also have a 4.0AH Ridgid battery from another tool.

I'm thinking of making a collapsible transducer pole to get the transducer below the ice and oriented correctly. Old hiking staff and pool noodle would be perfect.

The unit runs fine off an 18v 6.0AH drill battery. The fully charged voltage is 20.6v - above the spec of 20v. I don't know the full runtime as I didn't charge the battery before using it (battery was at 18.4v), but it ran 10hrs in Simulation mode before the battery over-discharge kicked in.

The Dsanke battery requires that the lock tabs be ground down until they are flush when the buttons are pressed, otherwise you'll have a rough time releasing it from a tool. The connector works perfect, although I didn't need 12awg wire.

The battery ran my 1/2" ice auger drill just fine. My charger is a Ridgid R86092 and recharged the dead battery completely in about an hour.

Here is how I made my Striker 4 Plus ready for ice fishing:
