If your only drilling 20 holes per outing, and want the lightest weight auger out there, look at a K Drill & a cordless Milwaukee 18v fuel drill with the 4ah lithium ion batteries. I have the 8″ version and can drill 25-26 holes in 12-13″ of ice per battery. Drills just as fast and my Strikemaster Lazer but only weighs 9 lbs. I’m not trying to sound erogant, but there is nothing else available that will drill an 8″ hole as fast, even at twice the weight. If you get the 6″ version, I’m sure you’d be at 30+ holes per battery. I’m still a gas auger guy, but for fishing thin ice (4-12″) this thing is incredible. I will be adding a Tanaka powerhead and I will have a 17 lb gas auger that drills at nearly the same speed as a Nils Master, but I can open up old holes.
