I only had the t2 for a short while, I have a lot to learn.I was doing test in discrimination and found it got stronger at high discrim, I also did test with the atpro which I be leave got stronger to. the etrac well its just different.I be wanting to do more test, but this white stuff keeps falling, so I made friends with my shovel.I got the t2 to move faster in more random spots but I think I should of went for the g2 not that I don't like the t2 , cause I found my first spanish with it , it's just I have the etrac and it hits some targets better visa versa.I just think a gold detector would of been used for different types of detecting well I'm not going to part with the t2 .ok I'm getting off track.I'll do more test thanks for the informative replies.
