First of all, I want say that I am not affiliated with Trophy Strike Company.
I had a chance to run one of their 120 volt auger last weekend. I am truly impressed. That thing cut through almost 3' of punky (soft) ice like a hot knife in butter.
Now I love my green 40 volt auger, but I think that I'm going to go a head and sell it. It's less than 2 years old and it works great.
The orange one is that impressive to me...
