50 Conductive Vs Combine - Target Masking & Falsing

[earthmansurfer]

I should preface this with my soil - somewhat iron mineralized. So, I am curious if people are experiencing what follows in their soil. Pics of my finds at bottom as well from my hunted out spot (first two coins are 1924, bottom coin is a Nazi Zinc).

I have noticed on a few non-ferrous targets that I get good hits in 50 Conductive and then when I switch to Combine I get an iron grunt. 50 Conductive falses MUCH MORE than Combine in my ground. Combine does seem to rule out iron better than 50 CO as when I am hunting in it I get a lot of semi-good signals (strong two ways, broken 4 ways). When I check these in Combine, 80% - 90% of those semi-good signals come out as iron, but it also seems to mask more at times which is ironic. I noticed this on the E-Trac in TTF and attributed it to my iron mineralized ground adding to already decent level of iron in the ground (pulling signals down).

The following video is on a small bolt that is rusted. I am including it because it responded JUST LIKE 1 of the 2 (identical 12-36's) Nazi pins I recovered a few minutes after I dug the bolt - but no video. (The pins didn't double beep though). The first Nazi pin hit fine in 50 CO but wouldn't hit in Combine (due to iron nearby). Then the next Nazi pin hit fine in both (no iron masking). My settings were the same in both 50 CO and Combine - recovery fast on (I tried it off as well), ferrous coin on (I tried it off and the first pin would have been lost in high trash due to a dropping Fe#). You can see in this video how switching to high trash in 50 Co rules the bolt out as iron but in Combine it never hits it no matter what. Further, it is interesting that though I get an iron tone in Combine, I'm getting a good VID above w/ cross-hairs but the splatter is a give away.

Thus far, I seem to be using 50 CO as my main mode and I check targets (using the user shortcut key) with Combine. I need to dig more of the targets that only seem to hit well in 50 CO to come up with anything certain. I am very curious what others are finding by comparing the two modes.

Yes, I'm sharing my learning process here.

Thanks,
Albert

Good video. Thanks for posting......

Good video and shows a real life view of what is going on. I'm very surprised it does not read the same in combined. You just made my mind up about how I'm going to check out "iffy" targets. And whats nice is the CTX can be switched between modes at the push of a button. This CTX truly is like having multiple machines in 1. I wonder if they make meds for dissociative identity dissorder in a detector? LOL

Albert another fantastic video, we are having the same results trying to find a mode that works better, because they are all different which may be good for one place but not another.

Thanks for the comments.

Joe - It is VERY CLEAR that 50 CO and Combine react very differently. I get A LOT of falsing in 50 Conductive but it isn't burdensome to me and I check them all real quick in Combine. But usually the falses break up when I turn 90 degrees as others have mentioned. The falses were in auto at +1 and up, and in manual too (auto sensitivity is usually at 25 in my ground).

As I said above, Combine misses some targets in iron, just like the E-Trac and TTF did. NOW, maybe this is due to my iron mineralized ground but I only have 20 hours on the CTX and already have noticed quite a few of these. So, I will continue to run both modes but I will in fairness to Combine, run purely in that as well, and cross check in 50 CO. (I'm not at all trying to bad mouth combine. I like it, the iron volume is actually not bothersome to me though I still suggested an iron volume control.) I still have an attraction to that warble in 50 CO but I like the higher tone I can get in the upper bin (which I don't run at max) in Combine. I can't win! (Minelab - give us variability back in 50 CO please.)

Niterider - Makes me wonder about the other modes none of us have been talking about (single tone, etc.) I wonder if single tone might be a depth demon like on some other machines. I'd love to hear if any one has played with the other modes, seems all of us are in the before mentioned modes.

Great video. I wish I could provide some real-world input but I've only found one silver coin at 6 inches and haven't found any other deepies to test different modes on. I'm at 10 hours with my CTX mainly searching a site that was productive with my E-Trac. I think my E-Trac got all the good targets (except the 6 inch silver dime I picked up last night). I really hammered this spot with the E-Trac.
