The dynamics of eskimo/Ion intrigue me. Same company yet they broadcast ion as the elite auger, I assume so they can charge an absurd amount for it. But I have to assume the technology is similar so I'm interested in trying out the new E-40.
Personally, I think weight is all that matters anymore. We've come so far in the technology of augers that speed is irrelevant, battery life is great across the board and type of auger bit is just a personal preference based on conditions you fish. I've tried just about every auger on the market and have yet to find anything that makes me want to upgrade from the MKE/kdrill. I won't sit here and try and convince you that the k-drill combination is better, just nothing superior enough to justify the cost.
