I see you have the xterra now..I’ve had all 3,,still have the xterra..To me the xterra easier to tell a coin from junk,those other machines at good but more relic than coin machines,but they will find coins just not as good as the xterra imo.
Garrett messed up the audio on the max imo,the at pro is so smooth,but the max is choppy sounding,like the at gold..Other than that it’s a good machine.
F75ltd2 is a beast,but it has a big learning curve,not a overnight thing..But if your willing to put the time in it’s a great machine.And deep.
You stick a tornado coil on that xterra and nothing’s gonna beat it in depth,not identifiable depth.Its the only machine that hits my 10 inch mercury dime in the test bed,and gives a solid 42..a little high but it’s deep..
The at max is deep in all metal but who could hunt that way,unless it’s clean ground.
F75ltd2,it’s deep too,and a million ways to set it up,it can be as ez or as complex as you want.
