I did a quick in the ground depth test on January 26th 2024 in a freshwater (frozen) lake beach cut using the Axiom with 11X7 Mono and DD coils, GPX 4000 with an older Nugget Finder 10X5" mono and Deus 2 using its 9" coil. Deus 2 was really along for the ride. I used it to test for iron mineralization and for clearing targets in the test area so I tested these targets with it too.
I had a 0.03 gram nugget at 2.5" depth, a 0.15 gram nugget at 5" depth and US clad dime (2.27 grams) and a US nickel (5 grams) at 10" depth. I had these targets taped to some 13" long shims and they were stuck about 2" into the vertical wall of the cut. Photo just shows the test setup. I only tested one target inserted into the cut at a time.
Iron mineralization was moderate to high as shown by the Deus 2 iron mineralization meter (graph at bottom left of display screen).
I first tested the GPX 4000 using General/Normal Mono coil setting with Gain on 12. That little Nugget Finder 10X5 coil gave clear, soft hits on both gold nuggets and also easily hit both US coins at 10" depth.
Next I tested the Axiom with the 11X7" focused core DD coil running in Fine/Slow with gain on 4. I had no problems ground balancing this DD coil at this site. The responses on both gold nugget targets were faint and audible but they were not as sharp as the GPX 4000 responses with the Nugget Finder Elliptical. The Axiom DD had strong, clear responses on the 10" coins.
Next was the Axiom with the 11X7" Mono coil running Fine/Slow with gain on 4. No problems ground balancing. The responses on the 2.5" and 5" deep nuggets were more sharp and rivaled the responses of the GPX 4000 with the 10X5" Nugget Finder. The Mono coil also gave strong, clear responses on the 10" US coins.
Deus 2 using FMF Goldfield and the Mono program set on 45 kHz, Pitch tones, -6.4 disc, had almost identical responses on the 2 gold nuggets. The targets responses were a bit faint but clearly audible. For me anyway, definitely "Dig Me" responses. Both programs were also able to elicit a response over the 10" deep coins. They were not strong responses but at least FMF Goldfield had enough information to throw up some fairly accurate target IDs occasionally on both coins. I also gave the Sensitive and Deep High Conductor programs a chance to hit those coins..........absolutely no response.
Hope this helps anyone that was wondering about the Axiom especially and even Deus 2. Both are very capable detectors in high iron mineralization even on small targets.
GPX4000 with that ancient Nugget Finder elliptical......amazing.
