MyFishFinder.com Just like iceshanty but warmer
...There were a couple times during the season when the cutting head iced up enough that I had to chip it off around the blades before I could drill again. I never had this happen to any other auger, must be careful not to lay it in the slush or snow without a cover on very cold days.
I am a hole hopper where I drill about 40-50 holes each outing. I'm super impressed with mine. I have the 6" version. It's light, compact, easy to use, and I would pick this over a hand drill/auger combo any day. No need to worry about wrist twist, added weight from a clam plate, great ergonomics and definitely not cumbersome to use. I can fit this in my Jetsled jr and still have a lot of room for other stuff. About the battery, SM claims the 6" version can drill 65 holes on a single charge based on 16" of ice. I haven't test that theory yet but came pretty close. I drilled about 55 holes on one outing on 12"-14" of ice. I had one bar left and forgot to recharge it. The next day took it out and was able to get 30 more holes. I could've gotten more holes out of the charge but didn't want to push my battery to its limit and shorten its lifespan. I think temperature, ice condition, storage of battery factor in a lot when it comes to battery life. Next season, I will be grabbing a spare battery and the 8" lite flite bit for when I want to target bigger species.
After you finish a hole, pull the auger out and spin it in the air for a few rotations. This will throw off the excess water and keep the blades from freezing.
