I have a Strikemaster 1200DP Electric Auger that I bought this year, and so far, I love it. It has a built in rechargeable battery pack (same battery as your vexilar, marcum, or aquavu), and weighs about the same as a power auger. You can also switch it to external power, and hook it up to the battery in your truck, atv, or snowmobile. I have only been using it on about 6 inches of ice so far, but it drills like crazy. I have probably drilled about 40 holes with it so far, and haven’t needed to recharge it yet(I have the 8 inch model). It has the same drill and blades as the gas powered laser mag (2 serrated blades with a chipper). Ice team did a test where they drilled through 3 feet of ice, they were able to easily drill 15 holes before the battery went dead. Consider that the ice in our area never gets three feet thick during most winters, even very cold ones. The biggest advantage I have found yet is that all you have to do is flip a swith and push a button down to drill your hole, I had 5 holes drilled yesterday by the time the guys fishing next to us got through their first ones, after letting their auger warm up, setting the choke etc. I have yet to use it on thick ice, but so far, I love it, and I expect I will still love it when the ice is two feet thick, because when the battery runs, out I’ll switch it over to external power and connect it to my ATV or truck. If you have any questions about it, or if anybody wants to give it a try, let me know, I fish almost every day, I would be glad to meet up with me and let you try it out.
