ATX Review by Bob Buss of Goanna Gold Detectors

The Garrett ATX Pulse Induction Metal Detector [All Terrain Xtreme] Report
The new Garrett ATX hit Australias shores this week & by next week the first customers will have their brand new machines. We, however have been very lucky to have access to a lender machine to reveal & demonstrate at our recent Goanna End of Season Muster held at Hill End NSW on the 2nd & 3rd November 2013. About 40 people gathered to be the first to see the new Garrett ATX. We had spent 2 days before the Muster testing the ATX in our test patch with buried targets at known depths. We test all our detectors in this patch so we know very well the depth capabilities, signal response & target location abilities of many different models. We approached the test without bias. We had already been privy to detailed explanation of the science & had heard verbal evidence of gold field tests conducted. We had also seen some air tests [which hold little practical use but can be useful in brand comparisons for testing individual aspects like response by same sized coils]. That is about as useful as these test are but buried target testing is different. Targets that have been buried for long periods, like ours are very good at assessing metal detectors because it is the closest thing to actual field conditions but still controllable. The bench mark Pulse Induction machine is the Minelab GPX 5000 so ultimately the testing had to be a comparison to see where the ATX lay compared to the GPX. As we only had access to the 11"DD [standard] coil for the ATX we were limited in our test parameters so we acknowledge that our testing is incomplete in regards to larger & smaller coils & we have not compared DD to DD or mono to mono coils either as we did not have access to them. We also note that the GPX 5000 is compatible with a vast range of after-market coils to enhance its performance whist the Garrett ATX only has 3 coils available & at this stage there is no after-market coil maker producing coils to increase the choice. However, the results we obtained from our test patch test were very surprising as the ATX passed every test we put to it. We even went as far as setting the GPX 5000 with an 8"x6" Nugget Finder mono into the GPXs Fine Gold setting to locate an extremely small 0.2gm nugget at 8". As expected the GPX located the target. Now, the surprise is that the ATX with its standard 11" coil also located the target.....that should raise an eyebrow....not bad for a standard coil.
