I can pinpoint to within one inch with my ace, but I have put hundreds of hours hunt time on that machine as well, don't get me wrong, I love my ace and have founds a lot of really good stuff with it. But a couple things burn me up with the ace.
#1 my buddy hunts with a DFX and he is constantly finding DEEPER coins in areas I covered, so I want more depth to reach the items I am missing. I use the stock coil (6 x 9) on the ace, so I am positive the stock coil on the X-70 will give me more depth, but how much??
It's possible that having a fixed GB on the Ace might hinder some depth in certain soils
#2 this is a problem that drives me NUTS. I hunt a lot of old homesites and as you know thay all have lots of iron, well if it is a large rusty washer the ace rings off as a coin signal. And if it is deep large iron it will ring off as a deep coin, always says 8+ inches on the meter. I start to dig then the signal goes back to iron. Very irratating. Will the X-70 let me know it is iron or is it fooled by deep iron as well?
Although the Xterra's are good at IDing iron digging larger round iron or large iron IDing as a coin can be a problem with most detectors. By sizing your target you can ususally see that's it's larger than a coin.
#3 when I get a nickel signal on my ace it is almost always can slaw, but when my buddy get a nickel signal on his DFX, it is usually a nickel, how does the x-70 fair in this area?
Nickels are right in the middle of trash. Having 12 notches on the ace more trash can be in that notch. Again sizing the target will help. The MXT will hit right at #20 for a nickel and Xterra 70 will be #12. With the latter two having more notches so to speak the nickel range will have a little less trash.
and why I am at it, how accurate is the depth meter on the X-70?
thank you all so much for your help and opinions, it is HIGHLY appreciated. As for now I am def leaning towards the X-70 as the detector I want. Now just got to save the $$$$.............
