I have noticed since I have been detecting in semi auto tracking, at the start of the day when I drop the ferrite ring on the ground, I can never hear the ferrite, but I do the thing with the quick track button anyway.
My question is: Once I have set up the detector to the ferrite ring in semi auto tracking, if I NEVER touch the quick track button ever again, and never take the detector out of semi auto, do I ever have to use the ferrite ring again?
It seems to me if you dont touch the quick track button in semi auto the detector always has the correct ferrite balance regardless of ground conditions. Dave
Ok I am just passing this link on, as I found it of interest I feel others on DP perhaps may be interested. This is the first I`ve heard of such thus have no idea if it is for real but I hope it is so, we want lighter, smaller, even bigger coils for our Zs. and as we`ve experienced, with the aftermarket coils for SD-GPX series, increased finds, why not for the Z?
I used the GPZ 7000 in the Summer of 2016 (with yellow ferrite ring) but it had so much ground feedback in my detecting area that I sold it. I found that the ground noise on the GPZ was masking targets over the GPX-5000 running in fine or enhance gold timings. (Damp & salty highly mineralized ground.)
Question: Has the latest software update with Locate Patch & Semi-Auto Ground balance helped significantly to handle this type of bad ground feedback?
I am considering buying another GPZ 7000 this Summer to try again.
Also, I found that the 5000 can match or beat the 7000 on larger chunky gold targets when running the larger coils.
(And of course, the GPZ was superior on some specimen gold types vs the 5000.)
Here is an air test on a 3 ounce wire gold & quartz nugget below.
The 7000 was at maximum sensitivity of 20 with the stock 14" GPZ Coil. (I didn't own the 19" GPZ coil to try in this test.)
I mostly ran in Difficult/General or Difficult/High Yield as Normal mode was impossible here, too much ground noise!
3 Ounce Wire Gold Nugget: (air test)
Fine Gold w/12" NF Round EVO coil: 17"
Normal w/12" NF Round EVO coil: 21"
Fine Gold w/15" NF Round EVO coil: 18"
Normal w/15" NF Round EVO coil: 23"
Fine Gold w/19" NF Round EVO coil: 20"
Normal w/19" NF Round EVO coil: 25"
Fine Gold w/25" NF Round Advantage coil: 20"
Normal w/25" NF Round Advantage coil: 26"
After my first outing with the GPZ I realized this machine is going to look pretty beat up in a few months. I pondered some different ideas to protect the top of the coil like stick on shelving paper or some kind of self adhering protection. I ended up testing a spray on rubber product called Plasti Dip. I first tested it on plastic and wood before blasting it on my precious and expensive new GPZ coil. After multiple coats and letting it dry you have a rubber coating that is pretty durable. When you want to later remove it, it just starts pealing and stretching like balloon rubber as it comes off, and it stays in one piece. Application is a little bit of a pain though. What I did was undo the coil fasteners and suspended the detector from the ceiling with the coil (cover off) sitting on a bench covered with cardboard. I retracted the shaft so the coil wire extended past the shaft knuckle. Then used masking tape over the coil wire where it meets the coil and masking tape over the coil eyelets so there's no build up there. After spraying each coat I had to remove the tape right away, and 30 minutes later re-tape before applying the next coat, for a total of 5 fairly thick coats.
It has proven to be quite durable and I will definitely continue to protect my coil with this method. Next time I'll spray it with the white color. Oh..., the nozzle of the spray can wants to clog between coats. Pull it off right after spraying and let it soak in mineral spirits until you need it. The product instantly dissolves in mineral spirits.
Another protective product I use is this self fusing rubber splicing tape. The picture is pretty much self explanatory. This product has to be redone more often. The warmer the temp. the more the rubber wants to kind of roll off.
I don't know why some of the pics rotate when I attach them.
