Something I've been wanting to do for a while now..I got another x ray generator couple weeks ago and wanted to try it out on my DR System.. Heres most but not all of the coils I have.
1. CTX 6"
2. TDI Pro 12" double mono
3. CTX 17'
4. XP Deus 9"
5. Miner John 8x12" mono
6. x cal 8"
7. Gold Monster 6"
8. Fisher Gold Bug two 6"
9. Nox 6"
10. Nox 11"
11-14 GPZ 7000 stock coil
Alright, I know nobody really knows the answer to when there will be a GPZ successor. Because of that, I'm just pinging for some opinions. We are currently a VLF only family that's interested in a detector that reduces some of the hot rock music we listen to here in Arizona. If you were in the market and didn't have a PI detector would you: A) get a used GPZ for $4500-5000 or B) wait and see what comes out over the next one to several years (depending on what rumors you believe)? And, a here's bonus follow up question. Does anybody have a guess what happens to used GPZ prices after the next model appears?
I would like to start a thread of peoples opinions on what they found between these two machines with various coils. I love my SDC and have found my biggest and smallest gold with it (8”). My GPZ has definitely gone deeper for gold (14”). I am about even on the total count for each, weight a being different story.
I understand that if you only have one detector then you want coil options, but if you got both I wonder what would be a better bang for your buck? A 10” Xcoil at $1000 or a 11”Coiltek at $310. Thats if they compare at depth and sensitivity.
Norvic I would love for you to state your opinions here, you seem to have the most on thses just based on other posts.
Out early this morn. to a shallow patch that produced nuggets up to 3 grams, the very first patch I found with the Z when it was less then a month old. 4 hours of detecting with the new 10" X coil, like both the 15 & 12 I found I could run the Z in normal on some fairly hot ground. Gold...…………. WOW it gets them small and that`s all it got small scraps, 10 to the gram stuff. Now the 10 " runs a little noisier then the 12 & 15, thus I dropped the sensitivity to 8, no knock sensitivity at all, I was amongst rocks and tall grass.
The patch I run this on, was the initial patch I run my modded SDC with the 11" Coiltek Extreme, by doing so I thought I`d be able to perhaps see some difference in the ability of the Zs 10" X coil vs SDCs 11" Extreme coil, not so, both are top small gold coils.
Whilst retrieving a nugget, the Zs threshold disappeared, I found the machine had turned itself off. I took the battery off and put it back, restarted the Z and no further troubles. Whether this was caused by a bad battery conx, or is related to the X coil I don`t know. I have never experienced an unexplained turn off before, thus will be keeping a eye on this should it occur again, I was using my sons Z as mine has the 12"X on it, back in the ute.
Am I impressed with the 10" X coil, I sure am, it is a top addition to my coil armoury, will see much use amongst rock and narrow gullies where the larger coils will not go, although I do prefer the 15" X which has replaced the ML14 as my go to coil on the Z, I love nothing better then new patch hunting, just haven`t the patience for the clean up of patches, although they are there for the days my legs can`t do the yards.
Have now got many hours of swinging, but I still am getting surprised at their performance, they`ve both put some weight in the pocket. Stability does not suffer at all from swinging against rocks or grass and importantly they are an advancement on the 2 ML coils in their depth and sensitivity capabilities. They have nice flat areas on top for pushing soil around with finger to isolate nugget. Also surprisingly they act a wee like mono coils (they aren`t) in that you can push any side, front or back vertically into hole or dug out soil to centre and retrieve the nugget which helps a lot in time it takes to retrieve signal. I`ve found I am using them both in normal much like I found one could with the ML19 but not so with the ML 14" which I found I had to use in difficult most the time on the ground conditions in my area.
I run general/normal/10-15 sensitivity/semi-auto/ 7 volume/24-25 threshold which both X coils maintain nice and steady except for the odd wet tree root, hot rock, charcoal or ant hill as per norm. All pros no cons at all so far, have become so confident and pleased in their ability have a 10" in the mail, should be here next week. They have lifted my Z game, I place results way ahead of warranty concerns, had no trouble making the patch leads for my & my sons Z. I have no affiliation with our dealer or the Russian manufacturer, just am a very happy user of these quality coils.
