Discovery 2200 vs Fast tracker

[Mutherpain]

I made a recent mistake and challenged my brother to a coin shoot out at a local park. I was armed with my Discovery 2200 and he brought what I thought was a toy, which was a bounty hunter fast tracker. He literally would find one and would then yell its denomination. He said most of his coins were 2 inches or less and my depth meter stayed on 7 inches repeatedly. I heard him yelling found about 3 to my 1. I couldnt keep up with it! From what ive seen, fast tracker finds coins. I did notice however, that it couldnt detect some of the coins I would pick up tho. Nice machine. Quick response time. He rubbed it in and I got ragged pretty hard. It was so much fun. Good times. Good times........
