Hmmm... Well, I got the Lesche in the mail today (Thanks Tony!) and even though I had been out twice I still had to get out again to try it (God bless my understanding wife).
My first impressions... It seems to be extremely well made and I can't imagine it not lasting a long long time. However, I really need to get used to it. I am so used to using a Swiss Army knife... I was able to dig some nice plugs with the Lesche, but it still leaves much more of a noticeable marks on the turf than my knife... and pulling plugs for every signal is so slow! This morning I was out for two hours and popped 106 coins with my knife. A few times with the Lesche I popped a nice plug, but it turned out the coin was maybe 1/2 inch under the surface.
So I went out an bought a screwdriver to probe with. Hopefully that will help, and hopefully, it won't scratch coins.
I'm sure the Lesche will be great once I get used to it.
