Legend Goldfield/deus 2 Mono/deus 2 Goldfield On Small Gold Targets

[Jeff McClendon]

This is not a versus video. It does show a problem that needs to be fixed.....

This short 4 minute 40 second video uses the Legend as an example of what I am used to for a simultaneous multi frequency detector in its gold prospecting mode compared to Deus 2 in its Mono and Goldfield modes on in the ground targets.

This has implications for small gold prospecting and micro gold jewelry hunting.

My hope is that XP will see this video and come up with a solution in the upcoming 0.8 software update.

Three targets: a 0.1 gram 14K gold earring back buried at 1.5", a 0.15 gram gold nugget buried at 2.5" and a 0.25 gram gold nugget buried at 3.5". 

I used the Legend to measure iron mineralization which was 5 of 10 bars so moderate mineralization.

There is plenty of EMI so the Legend is at 24 of 30 sensitivity. Deus 2 is at 95 of 100.

Legend Goldfield other settings: VCO audio, frequency M, ground discrimination pattern A for all targets accepted, recovery speed 5, iron filter 1, iron stability 1, threshold 12.

Deus 2 Mono other settings: Pitch Square tone Audio, frequency 40.4 kHz, disc at -6.4, reactivity 2.5, iron volume 3, audio response 4, silencer 0, threshold 8

Deus 2 Goldfield other settings: VCO Square tone audio, frequency FMF, disc IAR 0, reactivity 2.5, iron volume 3, audio response 4, threshold 8, notch 00-00.

Both detectors have volume on maximum.  Legend is using its external speaker. Deus 2 WS6 audio is coming from headphones placed ear cup down on my iPhone 13. The target responses are hard to hear..........not because there is something wrong with the volume.......just listen to the end of the video where I scroll through the Deus 2 Goldfield settings and listen to the very easy to hear audio. Nope, those targets are at or near the edge of detection.....that's why their audio responses are hard to hear.

XP really need to fix this insensitivity to small low conductors at least for Deus 2 FMF Goldfield............

I will talk about this to my dealers over here . Hope that they will show that video to XP ..

With silencer at 0 is it possible with that coil you ground balanced out the gold targets . Why GB so close to the targets. A reactivity  of 1 and silencer at 2 would yield much better results I think. JMHO

[Jeff McClendon]

Can’t run reactivity of 1 in any goldfield I know of due to iron mineralization. Running a higher Silencer setting in Deus Mono may also “silence” targets near the ferrous/non ferrous break along with non ferrous signals being pulled down into the ferrous range like two of these targets were in the video. 
 

No Silencer adjustment in FMF Goldfield. 
 

The targets were not ground balanced out with either detector. If I didn’t ground balance on camera people would tell me about it too

FWIW - Since you were at the edge of detection, Audio Response of 6 on D2 would have given you a marginally louder signal for those targets that were actually detected and gave audio, probably would not have changed anything for those targets that were not detected at all with no whisper audio.

[Jeff McClendon]

Running Audio response of 6 in the real world runs the risk of over amplifying hot rocks of all sizes and ground mineralization. XP’s default Goldfield settings have always been 3 or 4 for good reasons

My comment was mainly about having sufficient audio for your demonstation.

XP never had a notch feature for D1 or D2 Goldfield either until version 0.71 and that DOES reliably knock down the ground mineralization signal for me as well as some hot rocks for me in Relic mode (again perhaps at the expense of notching out some micro gold, but you did invoke it in your video), but you've got the expertise here Jeff as you're a natural gold detectorist unlike me, so I'll defer to you.

I'm not here to refute the valid point of the demonstration which is that D2 has taken a step backward from D1 in terms of micro gold performance and to get that edge back without having to keep a D1 or Orx around with an HF elliptical coil, XP needs to consider incorporating some changes to the D2 including:

• Having a mono frequency Goldfield mode
• Developing a small elliptical coil option
• Consider expanding the mono-frequency settings above 45 khz
• Improving the SMF micro gold performance  in Goldfield (which might obviate the need for points 1 and 3 above)

You weren’t in a gold field. You said it was 5 on a scale of 10, moderate mineralization according to the Legend. And as close as the Deus coil was to the targets I do believe they were balanced out. Why not balance a foot away. Same soil I would think.

This is why I don’t like to post videos…….. and why I sympathize with anyone that posts a lot of videos whether I like the videos or not.

I have a messed up ankle. I can’t get up into the mountains right now which are the nearest gold prospecting areas close to me. I have found quite a bit of gold with Deus 1 and the ORX at those sites. I had one chance with Deus 2 at one of those sites and I was shocked and very disappointed by its performance. Abenson had already warned me that might happen but I had the 9” coil so I had hoped for better results. Every other test I have done with Deus 2 on small gold nugget and micro gold jewelry targets using Goldfield has been exactly the same…..poor depth and poor sensitivity compared to Deus 1 and the ORX whether I ground balanced a foot away or a mile away.

Deus 2 could barely hit those targets in Goldfield in moderate mineralization. Maybe you can get an idea about how it does in 10 of 10 iron mineralization………

I tried to pick a site close by that had enough mineralization to challenge Deus 2. I must have succeeded since it couldn’t handle it very well.

Believe what you want.

I could just keep my mouth shut and be unhappy………or just give up on Deus 2.

I am trying to help make Deus 2 better for everybody that wants to hunt small gold nuggets and micro gold jewelry using it.

Good video Jeff and good info. There's always something people point out after you post a video that maybe the video maker overlooked. I find myself in that position all the time. Making videos is not easy and often times goes unappreciated by those watching.

I think XP watches the videos people make and if they are smart will make the changes people want. I'd like to think that's why they added disc notch to the gold and relic program after all the fuss I made about needing it gold hunting. But who knows.

But yea the Deus 2 is far from my first choice gold nugget hunting. It's too weak on small gold. Can it find gold? Yes as I've found a few nuggets with it. But the gold has to be in the .30 gram and above size to be detected on any kind of consistent basis. There's been a few people who want to say this and that about the Deus 2 and how great it is at everything. But I'll tell you straight up, it doesn't do well on small low conductors and higher the mineralization the worse it gets.
