when you use this for the first time, you are going to be amazed at how well it works. I was. I can actually go deeper that 2 feet in hard clay soil with it with ease. The only jams i got was when i hit a rock. It even a small 2 inch rock can jam it. Also, it is not easy to stay at the point where you started with it, so to solve that, i do a starter small whole.
