First hunt with the SEF 15 x 12...

[NealNoIN]

Weight issues: It seems as easy(hard) on the arm as the 10 x 12 coil which is surprising since it's so much larger. I used it for 3 hours and could have kept on going.
Performance: Just like other large coils, the site your a hunting has to have deep goodies in order to really benefit from the coil. The site I was hunting yesterday did not turn up any deep goodies but did turn up a couple of deep trash items that were impressive. Quarter size disk at 10+ inches was one I remember for sure. I will be testing the coil on 3 or 4 other sites where very deep old coins have been found with the 10 x 12 and see if anything else is down there.
Falsing: I dug more iron than usual but honestly think that was because I was trying to learn what this particular coil is saying. Also, the ground was very hard and I wasn't going to dig 20 inches to see if a pop can was sounding off real deep.
Finds: 1903 Indian, small "R" Railway Transit Lines token and 2 Wheat Pennies. I honestly thing the stock coil as well as the 8 inch coil would have sounded off positively on all of these.
Conclusion: This obviously was a site that didn't need the larger coil so more tests and updates will follow.

Well, at least you didn't get skunked Neal. Hope that new 15x12 coil works out for you. GL and HH.

I think we are getting at that point now where to large a coil just isnt what we need. We need improved TID in the software to take advantage of those coils. The larger coils have really been a huge boost to our finds..... but if we keep going we are going to look like those serious gold hunters with attachable handles and straps LOL. Let us know how it goes.

Neal,

This is a test I did at one of my floodplain dirt sites that has super deep targets. If you can carry out an extra coil, take a crappy dime and a ruler with you. After you dig a deep hole, stick the dime into the hardpacked side of the hole at a measured depth, say 10 inches. Then refill and pack down and resweep slowly from all different angles (I wrote down my results - just to be sure). Then (if possible), put the 10x12 or the PRO coil on and go over it again in the same manner.

If you get it clearly with all coils, then take it down another half inch and try again until neither coil can hear it anymore.

This takes some time to do, but I felt it gave me a good comparison on the feature that was most important to me - as much clarity of audio signal at extreme depth as possible. Since I know what the target is, I can better sense how the machine is interpreting the target. What I found was the display was all over the place and pretty unreliable, maybe one or two good readings mixed in. But the larger coil actually gave a little better audio tone on the extreme depth. Both coils lost the dime (no discernable audio signal - just very intermittent, light and scratchy noise) at 11.5 inches. I left my quickmask settings like I normally hunt for super deep targets with Deep and Fast Off - I did not go ferrous/all metal because I don't normally hunt like that.

I'm sure there are other folks who have done similar tests in their gardens and the like, perhaps with different settings - it would be interesting to see what everyone's results are.

Look forward to your next report!
