I'll never buy another gas auger. I have 2 OLD Jiffy's (late 60's "one armed bandit" and a mid-70's). They both run fine, but they are awfully heavy. I do use the newer one when fishing for pike / lakers. However, i bought a 6" Nero hand auger kit and a Dewalt 20V hammer drill with 5ah batteries this year and absolutely love it! With the 6" auger last weekend I cut over 40 holes through 2' of ice in 15deg weather ... and only used the first battery. Actually, the 2nd battery has never been used. I've used down to 0deg with no issues. I do put the extra battery in a cooler with a handwarmer as a backup, but like I said, it's never been used.
I can see an 8" Ion or Strikemaster in my future and getting away from gas altogether.
