For the last few weeks I have been using this http://www.automaticicefisherman.com/
Its a great tool to have in your arsenal. I was skeptical the first time I saw it, then I met the Co-inventor of the product, Kerry. He answered any questions that I had, and relieved some doubt that I couldn't help but have when it comes to new products.
Contact Kerry through his website or visit your local sporting goods store and check them out. They are worth the money.
