I’ve been using a Milwaukee Fuel with a standard 8” Lazer and a 12AH battery going on a decade now. I use it with a Clam Plate. Fantastic setup for ice under 24”. Haven’t been on more than 24” of ice in probably 15 years. For what a new StrikeMaster 24v costs, it’s hard to beat a drill setup unless you’re constantly drilling several feet of ice. Not saying a drill setup won’t do it but it’s taxing even on the best drill/batteries.
Having said that, I’ve never used any powered auger other than my drill setup. If you already have the 24v head, I’d just upgrade the auger bit and call it a day.
