PD, The Tesero Bandido has a manual ground balance which is very good in high mineralization. I think it's a good relic machine. It has good depth and is very good in trashy areas. It comes with a 8 in. coil. I use this most of the time, but if I want extra depth I use the 10.5 coil also the machine is very light and you can hunt with it all day and not get very tired. go take a look at one if you haven't already.
