I don't know the answer to your question, but do know that in Idaho, where Rob the owner shot this video, they can fish 5 rods at a time hence the 10 rods in the video. I have two units and am planning on purchasing more.
I was fishing the other day in miserable conditions and got skunked.. walking off the docks I called Ratherbe and asked him why the fish don't eat when it's miserable out side.
He said the fish still eat, the problem is you. Your cold so it changes your presentation. If I had these then, the wind actually serves as a jigging mechanism so my hands would have been in my pocket while the wind did all the work.
On nice days I will at least have one to keep my dead stick up and out of the snow but on miserable days I will probably fish two and keep my hands warm
Hope this helps. We should have at least one of these units at the next IceFishOhio event and I will also post results on the ones I have once I get a chance to use them.
