Regarding depth loss in discriminate, my MXT seems about as deep in coin and jewelry mode as prospecting mode with my 1.5 grain gold bead.

Also, Steve wrote some time ago how is older GB2 would function deeper in iron reject if the threshold knob was turned up all the way. He indicated that newer ones didn't seem to do that. Mine is a Los Banos unit, S/N 42223 and it clearly does it. I also believe it is very nearly as deep with iron reject on as with it off.

Just bought a nice 2 month old Gold Bug Pro to go with my battery of VLF gold detectors (see my post above) for the great comparison. I'm interested in how the various machines do around iron. Both the Lobo ST and the GBP are Dave Johnson designs and it will be nice to compare how the discrimination works on the two machines. On the GBP you can tin in all metal and still see the meter, but the idea of running in discriminate with minimum or zero applied and listening to,the audio differences appeals to me. Will have to check how much depth is lost doing that however.

Interesting product and potentially a life saver. Note, a subscription and monthly payment is required for use - details on the link Steve provided.

I'll have fun trying to replicate his results anyway! You might want to read Keith's stuff about the blended tones of the Gold Maxx Pro. It gets a bit mystical at times, but I think many of us have underrated the audio information available from analog systems.

Anyway - neat forum with a quick feedback tempo - hope we can all work to expand it.

I will soon have a Lobo super track to play with and there's a couple things I want to explore with it. First of all I will be comparing it to the other VLF gold detectors I have on hand – a Goldmaster 4B, a Gold Bug 2 and an MXT.

Besides that however I want to adjust the ground balance pot for the discriminate mode to suit my local conditions here in Arizona. Keith Southern posted a video and some information about that over on the Dankowski forum – here's the link. Keith describes at length the things about the Lobo that have him comparing it to the G2 - which, of course is the same electronically as the GB Pro.

In addition I want to try some of the stuff that Reg Sniff pointed out in his lost treasures review of the Lobo super track when it came out. He noted several interesting things in his test of the detector. First of all he believed he could clearly hear the difference between Rusty objects and foil by the pitch of the response -these targets giving a higher pitched response than lead (and therefore presumably gold). Secondly when he put the detector in the alkali mode he found that if he passed the coil over the target several times hot rocks and iron targets would fade but more conductive target such as lead and gold would not fade. This allowed him to discriminate out these targets while operating in the all metal mode with its greater depth.

I will see if I can duplicate any of these results when I get mine.

Proud to make the first post on what I am confident will be the most interesting and informative forum about detecting for gold on the web. With Steve in charge I think we can count on lots of thoughtful content - and wild speculation - on gentlemanly discourse - and bar room brawls - all in spirit of good fellowship.

Thanks Steve.
