Got to the beach today for about 3 hours. Hit 31 clad targets in a 75 yard by 40 yard area. This tells me that either nobody has hunted it, or nobody has the 705. 
I just used the stock concentric with no problem. Ran it in all metal and 99 tones.Was able to run sensitivity up to 27. Kept checking the ground balance. I think that the 10.5 DD HD would be optimum here because of the mineralization, but again the 7.5 did well.
I think this beach will eventually give me silver and gold. Will keep you guys updated.
Thanks Digger for the tip on running 705 in AM and 99, it has helped tremendously.
