I tried out my new Patriot yesterday and it seems to work fine. This is a different cat than I have been using (Xterra 705) hopefully it will be as effective in a lighter package. I don't hunt old coins much anymore, just jewelry and coins. This machine seems to have the punch to go down in those deep sand volley ball courts I like to hunt. It appears to be very versatile with a lot of options. I am using the stock coil for now. Anyway need to go log in some more time. good luck and HH.
