Thanks for the air tests! I wish it was that easy in the field LOL. I've noticed the Manticore, which I had less than a week, hits a bit higher on coins in the ground so I have been going by depth to dig them and have come up with 5 silver coins so far, two with nails, and most 6 to 9 inches ( I live in Western NY so coins sink a little further down in rich soil). I find the machine is much more sensitive than my Equinox 800 so there has been some falsing issues with deep nails, iron, etc. All part of the learning curve :) Overall I have been impressed and my area has become virgin once again!
My manticore does very well in air test, but when I go hunting I can not seem to get it to penetrate below 6 inches in any setting here in Ohio soil which is not terrible. I buried a quarter ,a dime, and nickel flat at 8 inches. It will not pick up any of them in any mode or setting. Is anyone else having this with their manticore?
I just got one(prob 20hrs of use now) and that doesn’t seem right. I found a super degraded wheat penny the other day probably 10inches. Have you been messing with the settings and forgot to reset your machine?
That sounds like something is not working correctly with your machine. I definitely dig targets well below 6 inches. I would do a factory reset and if that doesn't resolve it, I would reach out to Minelab. I've had great experience with their customer service.
