First Texas (Bounty Hunter, Fisher, Teknetics) - The Fisher CZX was targeted for 2016 but is running late, maybe late 2017 or 2018? Garrett - New coils/versions of ATX are running late, and new machine (AT Pro 2?) announced for 2017. Edit May 2017 - this has now happened as expected - Garrett AT Max Minelab - From Codan 2016 Annual Report, page 9: "In response to customer demand, two new products are planned for release in FY17. A larger coil for the GPZ 7000® will give a significant depth increase over the standard coil. In addition to this, an entry-level gold detector will be released to the African market at the end of 2016. This product has been specifically designed for the African market to fill a gap in our product range, and is expected to quickly take market share from competitors." Edit April 2017 - this has now happened as expected - Minelab Gold Monster 1000 Nokta/Makro - New selectable frequency Nokta Impact announcement due by year end and available in 2017. Edit February 2017 - this has now happened as expected - Nokta Impact XP - DEUS V4 and new high frequency coils announced and to be available in 2017 Edit February 2017 - this has now happened as expected - Deus V4 White's - Lots of talk this year about exciting product in pipeline but that is about it. Obvious to me anyway is that any old black metal box designs are on the chopping block with replacement models in the works leveraging the MX Sport housing.

I should have linked to the earlier forum threads. The coils were announced in January by Garrett and are now overdue. Yes, a mono is also expected. The one in the video and shown below are prototypes, not finished product

Shows unique sliding center mount design....

The original black box Goldmaster II was the first hot machine running at 50 kHz, a very high frequency at the time. The Goldmaster II preceded the Gold Bug 2 and for a time the Goldmasters were unmatched in sensitivity to small gold until the Gold Bug 2 came out in 1995. The Goldmaster V/SAT, Goldmaster 3, Goldmaster 4/B, and finally GMT at 48 kHz are all just variations on the theme and none of the newer models are appreciably more sensitive than the original 50 kHz Goldmaster II model. Companies that do not answer emails within 24 hours are quite deficient in the 21st century.

If you have both coils and just the one coil falses a lot that proves the problem, as coil swapping is the best way to diagnose the issue. Getting the detector to a Whites dealer and trying another coil is the normal solution if you only have one coil. If you do not get out and detect much just using the good coil is a decent option - there is only minimal sensitivity difference but the stock coil will cover more ground and reach deeper on some gold. I have to say I have always favored the smaller coils myself for super hot machines like the Goldmasters, GMT, Gold Bug 2, and Gold Racer. Whites old style thick coils are foam filled. It is lot unusual on the larger coils to have the foam break down and deteriorate from long term knocking against rocks. This in turn would cause movement internally, generating false signals. The 14" x 8" coils seemed especially prone to this problem. That is unlikely to be the problem with your small coil but rest assured coil failure is far more common than control box failures, many times over.

Thanks JP. Minelab sure likes making new part numbers through incompatibility. Why have three similar but incompatible wireless audio systems? I do like the idea of a volume control directly on the module and wish my GPZ in particular had that feature. Maybe they will retrofit the system into the CTX and GPZ at some point so everything works together.

I like this system because it has a built in speaker which other competitors lack. What I wonder is whether the receiver module is compatible with either the WM10 or WM12 modules? I would think it might be and that by getting this a person might be getting a second receiver module that could be used as backup or in tandem with the WM10 or WM12?

Hi Jim, Sounds like a bad coil to me. That is exactly the symptoms one expects from a coil losing its integrity.

Welcome to the forum! Only coils made specifically for the Gold Strike will work on it. It does not cross over with any other models.

They work fine, as does the Nokta.

Here are some manufacturer specials running now. These are from the manufacturers and so I assume they are on top of any deals already offered by a dealer, but do check and make sure if considering a purchase. If anyone finds other deals go ahead and add them to the thread. I have not found anything for Garrett, Tesoro, Makro/Nokta or XP yet.

The DPR 600 is a related stripped down product, not the same...

Part Number 1627100 MSRP $149.95 Minimum Advertised Price (MAP) $127.45

The G2 is the Teknetics version of the Fisher Gold Bug Pro (Fisher and Teknetics owned by First Texas, so a GM/Chevy type thing). The G2+ is the Teknetics version of the Fisher F19. The main thing you get is a backlight, notch disc, and iron volume control.

Big photos and some Internet connections sometimes do not mix for uploading. Reducing image size is usually the fix. I found a great easy and free photo resizer - Simple Resize Apple http://simple-resize.appstor.io Android https://play.google.com/store/apps/details?id=jp.tekunodo.simpleresize&hl=en

I am not frustrated Jason. I am sorry if I had anything to do with making you feel guilty by responding to your post. Like I said, it is best if I just stay silent.

Hi Jason, You are using the outside diameter of the coils to figure area of an ellipse, whereas the blog entry referenced is using a best fit at the outer edge of the TX and RX windings. This makes the 19" x 18" coil closer to 18.68" x 16.65" and the 145" x 13" coil closer to 13.27" x 11.96". These measurements in turn deliver the 96% (95.8%) larger area as referred to in the blog entry. See the diagram below. I think the basic premise that the coil is underperforming is flawed and so attempting to figure out why that may be is an exercise in futility. Again, I think this all comes from Minelab trying to get all scientific about things and put numbers on relative performance. It gets them in trouble every time, but here we go again. Same story, different act. New Minelab item comes out, much pulling of hair commences, product deemed deficient compared to people's expectations. Then time passes and item praised later as best thing ever as expectations adjust to reality. Most recent examples, GPZ 7000 itself and SDC 2300, and earlier virtually every SD, GP, and GPX model. I never thought a larger coil was going to be magical myself as every oversized coil I ever got in the past came with too many expectations that quickly were dashed on reality. Reality is those big deep nuggets just out of reach are far rarer than people think. Oh well, I should just let it all settle out without comment as I come off sounding like I am making excuses for Minelab. It is just all so predictable however.

Excellent point Steven. Usually a larger coil does cover more ground in a given period of time and that alone can result in more gold. However, for myself at least the GPZ 19 would not be a general hunt coil but one intended for hunting specific areas very carefully looking for suspected deep, large nuggets. When used like that I would very likely slow way down, especially given the extra weight of the coil and need to keep it under careful control for best performance. There may be those who can swing that big coil all day long just as fast as they can swing the GPZ 14 but I am not one of them.

Hi Dave, Actually the disclaimer has been out there since day one though now it is more detailed, as can be seen in the post of the materials originally at http://www.detectorprospector.com/forum/topic/2584-minelab-gpz-19-coil-full-official-information-release/ Not that it matters. Either you are happy with the coil or you are not - I hope things improve for you on that score.

Minelab just updated the October 26 blog entry at http://www.minelab.com/usa/go-minelabbing/treasure-talk/the-gpz-19-coil-does-it-really-detect-30-deeper to add the following information at the end of the entry. Note that to get good coverage it is the smaller receive windings that matter, not the larger center transmit winding.

I am surprised not one answer on this one. But a lot of people here are swinging a GPZ so that may be part of it.

A new Treasure Talk blog by Jonathan Porter. "Following on from my last blog about the GPZ 19 coil, here are some further tips to help you get the best from your GPZ 7000, irrespective of which coil you are using. The GPZ 7000 is not difficult once you come to terms with the way the technology performs over the ground. It is a blend of behaviours which are dictated by ZVT technology, the Super-D coil design and the detector’s ability to tap into the full gamut of target information, thanks to being able to run a very low noise floor without any major trade-offs to audio stability."

Welcome to the forum! It just depends on the ground mineralization and settings. Here are some air tests of the Lobo along with settings used you can use to bench test your machine...

I have not used both but I hate to see questions go unanswered so will offer an opinion. I doubt the performance difference is enough to worry about. To me the big difference is an open spoke design versus closed design. The NEL coil is a couple ounces lighter but the Fisher coil less likely to hang up on stubble or other obstructions. I would consider the type of terrain you are hunting very carefully and think about which physical design would work best for you.
