....However, I only used the 5x10 coil the one day that I was there. This combination worked very well for me and wish I could have hunted all three days, but became ill and had to leave early.
If I had hunted in the all-metal DISC mode instead of prospecting mode I doubt very seriously that I would have found anything at all. Not just because the prospecting mode went deeper, but I think people often forget (or don't realize) that when you hunt in DISC mode you don't get the same wide footprint (hot wide-scan effect) that the true threshold based all-metal mode can give you. Even with DD coils you can better ground coverage if you don't use DISC mode. Whether this is an audio trick that fools us, or whether this can be proved in testlab analysis does not matter. The fact is you will hear targets better in prospecting mode. (When I switched to DISC mode upon hitting a target, I usually saw jumping numbers that caused too much visual analysis that wasted time. If the next version of the X-70 has target ID in prospecting mode this will save MUCH time....I do NOT dig all targets and do not care if I leave a good target in the ground for the next person. It's just a hobby.)
As a side note: On that first day of the DIV IX hunt I spoke with 5 different MXT users who also were using a 5x10 coil. NONE of them had found anything, and had not heard ONE signal all day. I asked if they were hunting in prospecting mode, and they all said they were in RELIC mode.
I'm glad I did not bring my MXT, but I would have at least tried the prospecting mode that I suggested to all 5 of this people who looked at me like I was crazy and walked away when I suggested this. I wonder if they even tried what I suggested.
The X-70 is a keeper for sure, and I need to sell my MXT. It won't be used anymore.
