New GPX-4500 GPX-5000 Mods...
« on: February 15, 2015, 12:13:01 am »
Looks like we can get  40% plus on big targets with our newest mods... 40% also on small Gold.  Just need some field testing done...

This applicable to all GPX GP and SD2100 SD2200  detectors.

More information to be released via the news subsrciption on the home page.

Sounds great Woody. Hate to think what the new GPZ is going to cost.

What are your thoughts on the ZVT technology?

Most of the magic happens with the coil, you could use a DD with a SD GP GPX up the input gain and extend the pulse length and obtain similar results on large Gold targets.

GPZ-7000  I hear it is $10,000 +

Yeh I reckon $10k will be close to the mark. Popular though with the first batch already reserved out.

Your front end gain certainly makes a difference but seldom able to crank right up in mineralised ground. Mind you I tend to stick with a mono.

The newest mods will allow you to crank it up nearly all the way in hot ground.

Hi Woody
  My SD 2100 you modded for me years ago still works great but this is good news on the GPX's.  Will these new mods work with my GPX 4000?

Wes.

There is a good article in the March edition of GGT on Experiments with ML Detectors...  I have some fantastic news coming out about new mods for 2100 and all models up to the 5000.

You want 50% depth increase on small Gold?  No problem, You want substantial depth increases on Big gold deep? No problem.

  Our the new mods for the 2100 in addition to the ones you did on it several years ago.  What I would like to get is a voltage regulator for my 2100 that would go in line in the cable so I could use my gpx battery that is for my 4000 for my 2100.  I currently have the 12 volt Reeds Lithium battery with the voltage regulator turned up to 7.4 volts but it won't last forever and I cannot get another one.

  Sounds like I just may be sending you my 2100 again to have the additional mods done on it.
  If I do that I want you to build me a voltage regulator so I can use my GPX 4000 battery with my 2100.
  Take to you soon

  Any idea yet what the additional mods to my 2100 would cost plus making an in line voltage regulator to run between the battery for my  4000 and my 2100.

Hi, been very busy here, sorted out how to get the sensitivity of a sdc2300 into the gpx detectors , should come close to the performance with the 2100, also super depth mods for larger gold is done.

  I might be getting a GP 3500 for a really good deal.  I think the 3500 was the best analog machines Minelab came out with.  Would it be a better choice to have modded than my 2100 that's already been modded?  I might just buy this 3500 and send it to you and have all the mods done to it instead of sending my 2100 again.  Your thoughts?

Wes.

The 3500 is a very good adaptable design, so maybe a better choice of detector.
