I will let you know , a buddy of mine has 1 and he loves it says it will drill about 150 holes per 1 pound tank for a foot of ice.
I ahve had one since the first season they came out. I have only had one issue with it. A below zero morning, the propane froze up and it would not run. I had to put the propane can in my bibs for a couple minutes to warm it up. After that, I was good to go. Now I keep a soare tank in the truck for the ride and leave that can in my coat pocket just in case.
I have had mine out a bunch or times now and it put my buddies gas augers to shame this thing is fast,did break the throttle lever ,as for cold my tanks have never been inside and are in milk crates on the way out to the fishing grounds,never had a problem with starting the auger.
The propane augers are nice but they are not as fast as the gas version. I have the 3hp stx and my buddy has the propane and mine is definitely faster even though they are both 3hp.
Well mine came yesterday I put it together installed new propane tank and it will not start I called jiffy and they are sending a new power head.
