Ralph is correct on the probe, my X1 probes all false above a gain of 7 in our local soil. But then so do the main coils. On the SE I field tested the gain and found the scale to be no different than the XS or II. I turned my SE gain down to 5 and medium deep targets got way to quiet, I really had to pay attention to hear them. Since these same targets blast out loud and clear on my XS and II with my gain at 7 if someone told me I had to run my gain at 5 on an SE to reduce the falsing I'd say, forget the SE I'll use my XS or II. Keep in mind I have heard pip-squeak DEEEEEEEP silver signals with my gain at 7 that I almost missed so a gain of 5? Not happening.
I also tested the sens, again I did not see a difference between the XS and II regarding the sens settings. Sens 26 on the SE gave about the same performance as the XS and II in terms of depth. The SE WAS hotter on small targets than the XS, so I'm not saying there is no improvements. But again if someone said I had to run my sens at 18 or 20 to get the SE to operate properly I'd say no thanks, I'll use an XS or a II.
The last day I tested the SE, I tested the ML 8 inch coil on my SE. I had to turn the sens down to 20 and the gain down to 5 to get it to smooth out in terms of the falsing, never mind that is a much smaller coil than the stock coil. Depth went out the window. I put the stock coil back on, bumped my settings back up to sens 26 gain 7 and it falsed like nobodies business.
Then got a solid repeatable high pitched signal, silver quarter ID. It reapeated good and I mean really good from all angles except one. That is normally a 100% dig it signal on an XS or II and a virtual lock to be a good coin. I dig it up and...2 inch square nail. I was floored, I have dug litterally thousands and thousands of targets with the XS and II and I have never seen them fooled like that. It wasn't even bent, dead straight. I walked immediatly to the truck and put the SE away, been using my XS since.
