"I use one I have found 13 wheats and a merc so it works good for me. although I'm having trouble finding the focus point"
Since I posted that I have upgraded and given the BH to the wife who gets along with it real well for a hand me down. I got a Ace 250 and she does just about as well as I do . I am curious and a bit lost at your problem of the "focus point" ? Unless you are talking of how to pinpoint with it or where the sweet spot is. To take a long shot at you puzzel I will say like all other MD's without a built in pinpoint. Imagine an X or + accross the coil. When you get a signal . move the coil forward and back over the signal area noting the center of the inner coil . then move the coil side to side noting the area of the strongest signal as in the forward and backward movment. then imagine that stongest sound in at the X or + in the middle of the coil and that should be your dig spot .
If this wasnt the answer you were looking for . sorry
Hi BH users my wife gave me a lone star for xmas 4 years ago . I have over 100 bucks in coins, 1 silver ring and many other pieces of jewery. My big find was a ipod that I managed to find the owner and returned it (that was one happy 13 year old). I will probably up grade someday but for now I am happy with the lone star just keep running down batteries and learning.
Just sign up and new to metal detecting. I just bought a used BH lone star from a pawn shop today and going to give it a trial run tomorrow and play with the settings, downloaded the manual from there website. hope it works
