Phoenix and anyone else in AU, did the Lexan skid plate impact the performance of the GPZ?

Thanks,

Bill

Paul, does the acrylic (plexiglass) impact the GPZ performance, it's alot thicker than most coil covers? 

I hope not, because I just bought a sheet of the Lexan product from HD.

I've also included a picture of the terrain where I was working, the solid skid plate I was testing for Nugget Finder made it possible to detect here.

I'm interested in the NF skid plate....are they ready to ship to the USA?

Merry Christmas and Happy New Year's,

Bill

Maybe Steve or Chris  can contact Miner John to make a HD 19" coil cover, like the excellent covers he made for the 14" coil.

Merry Christmas,

Bill

Hey HardPack, if you want some excellent reading and research materials on Nevada geology, search the Nevada Bureau of Mines and Geology which has numerous geology books with maps and plattes on the counties of Nevada. Bulletin 59 is Humboldt County and Bulletin 89 is Pershing County.

Hey Joe, maybe we can meet at RP next year in early May???

From my understanding, the above chart was made based on actual in-ground test results in their ML test-beds on mild soil. Sure it may be marketing material, but it is from scientific testing...not "mathematical assumptions". 

I've ordered mine for 2017 detecting.

Bill

Well based on this chart from another forum, the GPZ 19 coil in mild soil is out-performing what the Aussie air-tests are showing. Maybe their soils are negatively impacting the air-tests.

Bill

Well here is the reply I received from my dealer when I asked about the discount for early GPZ buyers:

"Bill,  I had the same question asked yesterday, which I forwarded to Minelab USA.

I was just informed by my detector dealer that US customers that bought their GPZ before the price cut won't be receiving a discount like the Aussie customers are receiving ($500 AUD)...what's the deal Minelab USA???

Bill

Steve, I'll keep posting on the forums until I find a seller. Somebody must have one collecting dust in their closet.

Bill

Thanks Rick!

Bill

I've heard that Bill Lahr repairs the coils in Whittier, CA. Does anyone have his tel# contact info? Thanks,

Bill

Chuck, took your advice and I'm looking for one for my MXT. Thanks,

Bill

Maybe Miner John could make one using the new flat or spiral coil winding that Coiltek and Nugget Finder is currently using:

Evolution Technology: In traditional bundle wound Litz coils, the individual turns of Litz wire are grouped together to form what essentially looks like a rope of wire. The Evolution Coils use the same Litz wire; however the individual turns of wire are laid side by side to form a wide flat strap of wire. This method of winding is called a Flat or Spiral winding. Flat winding reduces the capacitance between the wires and produces a much more efficient coil. It also dramatically increases the surface area of the winding, thereby producing a coil with both improved depth and sensitivity across all target sizes.

I would buy one for my MXT Pro!

Great write-up Ron! I am a repeat offender and have been personally trained by Gerry, Ron and Lunk in 3 different 3-day training classes and learned many new things each time.  When I read Ron's words, I found myself nodding YES in every paragraph. I bought my first GPX and didn't have the benefit of professional training and guess what...I didn't find any gold! That quickly changed after my first training class and I took alot of notes that I still use today to refresh my memory after a long winter in Colorado. I have built quite a library and still read information on detecting like a new kid in a library. I'm still learning from the pros and will always be open to new tips. Thank you for your service to the nugget hunting profession.   =

Bill

Gerry found an amazing gold specimen in dredge tailing piles!

I agree with JP on how great the GPZ is compared to the numerous choices required to maximize GPX 5000 performance!

My only request is a smaller coil for the numerous tight search areas that are covered with boulders and heavy brush...the GPZ coil is too big for those areas.  So ML or CT or NF, if your reading this, give us a couple of coil choices for the amazing GPZ and we'll all be happy!

Happy New Year,

Bill

Congrats Paul and thank you for helping another prospector with your generosity! My wife is a frequent visitor to the Cheyenne VA and I know how challenging your job can be...hopefully we can meet out in the goldfields one day, so I can thank you in person for all you do for our vets.   = 

Bill

Great job in northern NV! It seems like it was only yesterday that you trained me at Rye Patch...so much to learn from a pro.

Training makes all the difference in the world. Thanks Lunk and the great folks from Idaho,

Bill Moore

Thanks Chris, it's great to have some pros in the US that can tackle our tough questions and provide insight into the complexities of the GPZ 7000. Hopefully the ground will dry out soon and some better gold will be found!

Bill

Thanks Steve for your thorough review, insight and posting.

Once we PI users understand "Forget about how your PI acts and works and if anything treat the GPZ more like a Super VLF than a pulse induction detector. Certain old VLF tricks work with the GPZ. The main one being - get that coil off the ground!!"

The GPZ manual on page 49 mentions "the sweep height as 1/2" above the ground and parallel to the ground at all times. Avoid excessive brushing of the coil on the ground". 

Old dogs can learns new tricks, if they read and then re-read the information, until it finally sinks in!

Bill

Chris, running the threshold silent is an interesting choice. My main questions about running the GPZ coil an inch above the ground was three-fold:

1. I was always taught to scrub the ground with my coil because it increased the detectable depth on targets, and had done that with all my GPXs and never had a problem with ground noise...maybe I was just in low mineralisation, dry soil?

.

2. Does the GPZ coil have to be run an inch off the ground due to it's design and sensitivity? I had not read that until JP's post.

3. Has anyone found a solution to reducing the noise while using the GPZ in wet and salty soils

Looks like I'm going to have to re-learn everything with this new GPZ 7000 detector!

Bill

When I was out detecting in Rye Patch last month with the GPZ I had a really hard time dealing with the wet/salty/mineralised soil. I just re-read an eye-opening tip from JP on another forum and was wondering if anybody else was keeping their coil off the ground. 

http://golddetecting.4umer.net/t21493-how-to-remove-noise-from-debris-gpz-7000

JP recommends to not scrub the ground and keep the coil 20 to 30 mm off the ground when swinging the coil.

Jason, great looking gold...save some for me!   Keep stretching and excercising your back so you can get back out there. I'll be there on the 23rd. Save a piece of good looking gold for me to buy. Get well soon,

Bill
