I'll second that. I got a Kemp Wiggler for Christmas. After diggin with full size picks ,screw drivers and shovels for the last two years. A wiggle pick and a throw mat proved themselves to me in the last couple weeks. I'll never go back.
In another post by this one titled diggin tools: Hal and another person are talkin about a cool tool, I have also used one of those once. It worked very well on rimming in midden. The only draw back is it designed to be used from the top of the hole. The wiggler works well in the hole. Good luck
