discrimination on Surf PI 1.2 ?

[ice413]

I was out yesterday with my Surf PI 1.2, and it works great.
BUT, i had to stop and dig every 3 feet because of all alu-junk. I'm not intrested in
old bottlecaps etc..

Is there anyway to discriminate alu on a Silverdog Surf PI 1.2 ?
If so, how do i do ?

surf pi works in all metal. no disc. you have to take a look on VLT tipe detector now.
