GPZ 7000 Ground Smoothing Options (Software Update 2)

The GPZ 7000 has set a new benchmark for sensitivity over a very broad range of gold nuggets. However, a by-product of its exceptional sensitivity to gold nuggets is increased susceptibility to soil anomalies and unwanted interactions with the ground matrix. One such unwanted interaction is with the conductive (salt) elements of the ground.

Early Season Gold

It has certainly been a busy year for me so far, with not as much detecting time as I would like. Still I have been getting out a little and thought it was time to share a few photos.

My first couple of bits were found with the Minelab GOLD MONSTER 1000 (GM 1000) on some scouting runs.  I am liking this detector as a grab and go unit for checking areas out quickly.  I am not trying to hunt for max performance but instead looking to cover a lot of ground quickly to check things out.  I have learned the GM 1000 auto sensitivity actually suits me well for this.  I just fire up the detector in All Metal Mode, full volume, and start with auto sensitivity set at Auto+.  Then I just start swinging.  If noise intrudes (usually in salt areas), I will back down to Auto (there are just two Auto settings available Auto and Auto+).

GPZ 19 compared to GPZ 14 - Nugget Dig!

Like all things new, it takes time for results to feed back into the general community. Overall, there have been some very good reports from people using the GPZ 19 coil. Early adopters who have been tough enough to brave the heat of summer here in Australia have been reaping the rewards, as well as fast-tracking their experience levels for when the weather cools off, come Easter time…

Better Understanding Zero Voltage Transmission (ZVT)

Following on from my last blog about the GPZ 19 coil, here 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.

Practical tips for using the new GPZ 19 Super-D coil

With today’s release in Australia of the much anticipated GPZ 19 coil, I thought this would be an excellent opportunity to provide some practical field advice to enable early users to get the best results from this ‘beast of a coil’. I’ve been testing and refining it with the Minelab engineering team for quite some time now, and have to say, it’s worth the wait (weight), in more ways than one!

The GPZ 19 coil – does it really detect 30% deeper?

With the imminent release of the GPZ 19 accessory coil, I thought it was worth discussing its depth capability and how our 30% performance statement was derived. Typically these types of claims are commonly greeted with much concern and doubt, before many are even able to get their hands on the product and test it for themselves. Even then, there are a wide range of settings to choose from and soils to test in, so results can vary greatly depending upon the test conditions. Also, larger objects will typically be detected deeper for the same size coil. Anyway, some background information first…
