KHS800-0353GMX Series

GOLDMASTER® Series OWNER’S GUIDE GMX SPORT WATERPROOF GOLD DETECTOR with XGB Technology XGB TECHNOLOGY SPECIFICATIONS XGB TECHNOLOGY is a patent-pending automatic ground balance system. It is purpose-built for operating a high-frequency VLF gold nugget detector in difficult ground conditions. Traditional VLF detectors struggle to balance rapidly changing ground mineralization and hot rocks. With XGB technology, the GMX is able to track small changes in soil composition as well as longer-term shifts in both ground phase and strength. This allows it to operate in ground that traditional VLFs struggle in. Users have extended control over the range of XGB in the Goldmaster’s All-Metal mode. Simply enable Iron Cancel to expand the ground filter in moderate soils. In very challenging soil conditions, hold the Iron Cancel button and select a higher setting for maximum performance in variable ground.

Optional Coils4” x 6” GMX or 4” x 6” 24K Introduction White’s Electronics, Inc.’s Goldmaster® platform has served electronic prospectors well over the last 20 plus years, resulting in income for professional miners and diversion for hobbyists. With modern advances in DSP, improved ergonomics, and performance increases, the GMX SPORT represents the next generation of high-frequency induction-balance waterproof gold nugget detectors. When our engineers set out to build the GMX, the goal was simple: Improve the user’s chance to find gold by combining the electronics of the GM 24K with the waterproof, rugged design of the MX SPORT. The obvious way to achieve this goal is increased sensitivity. The GMX features a 54% increase in coil voltage over the GMT. You will see this in increased sensitivity to small nuggets. Even at lower gain settings the GMX is an extremely “hot” machine on small gold and specimen nuggets. Experienced electronic prospectors know that more sensitivity is not the only answer to increasing the odds of success in prospecting. A machine’s ability to track and cancel the ground is often the biggest challenge we face in our search for gold. That’s why the GMX Sport features the all-new ground tracking system we call “XGB” (Xtreme Ground Balance). This system works with multiple ground points to ensure stable oper- ation. The GMX also features Iron/Hot-Rock cancellation in both audio modes, expand- ing the ground range even more for quiet operation in the most challenging ground. When the nuggets are few and far between, prospectors often have more success at sluicing, panning, or dry washing. You will find an all-new mode in the GMX, called “Ground Scan” that can help you successfully track and mark black sand or other mineral deposits in stream beds, washes, or even under ground (where the backlight comes in handy). In addition to these new features, old standbys like Variable Self-Adjusting Threshold (vSAT), Ground Grab, TracLock, and adjustable audio options help users to setup the machine as they see fit based on ground conditions and personal preference. Where other companies rely on completely automatic operation for limited uses, White’s Electronics, Inc. believes in giving you the ability to adjust a machine for a wider variety of conditions, hopefully resulting in more gold in your pouch. With a combination of patience, research, and a little luck, you’ll get your GMX’s coil over gold. But be warned, if you don’t have gold fever yet you will after your first nugget!

The results of this test pertain only to the sample(s) tested. The specific description is noted in each of the individual sections of the test report supporting this certificate of test. This report reflects only those tests from the referenced standards shown in the certificate of test. It does not include inspection or verification of labels, identification, marking or user information. As indicated in the Statement of Work sent with the quotation, Element’s standard process is to always use the latest published version of the test methods even when earlier versions are cited in the test specification. Issuance of a purchase order was de facto acceptance of this approach. Otherwise, the client would have advised Element in writing of the specific version of the test methods they wanted applied to the subject testing.

The difference is the result of tolerances in the measurement system that cannot be completely eliminated. To the extent that technology allows us, it has been our aim to minimize this error. Measurement uncertainty is a statistical expression of measurement error qualified by a probability distribution. A measurement uncertainty estimation has been performed for each test per our internal quality document QM205.4.6. The estimation is used to compare the measured result with its "true" or theoretically correct value. The expanded measurement uncertainty (K=2) can be found included as part of the applicable test description page. Our measurement data meets or exceeds the measurement uncertainty requirements of the applicable specification; therefore, the test data can be compared directly …
