I Saw The 5000 Up Grade Test

Wow did not know we’re this was going to go was there a guy named  Ismal  sp ? Who did the first mods I believe the SD 2200 I have was done by him

The first mods were done by Barrie Johnson and Ken Roberts, for the SD2000 only. Ismael Jones expanded on this with higher sensitivity frequency crystals, voltage regulator and filters, plus an amp. He then created mods for the GP's and Woody also started around the same time. Mick Spiteri came on the scene when the F1A4 mine detectors were being dumped on the market and he created the mods for those and then expanded into all the other ML PI's. Ismael still has his site up and not sure if he still does the actual mods.... he has the info on  the mods for all the machines up to the GP3500 for anyone to download: Ismael Jones site

Something to consider that I never see anyone write about.

I had a 4500. With the amount of different settings, when you are not finding anything, you start to question yourself with the settings.

You can lose confidence.  For me, confidence in your settings and equipment is everything! 

The 7000 seems have a great filter, eliminating a lot of ground noise, and handles emi a lot better. I know I have found sooo much more gold since going to the GPZ no mod would convince me to back to a 5k or 4500k. I also have a 6k, and I don't use it as much as the 7000 either.

It is strange how the Extra Deep Gold Mode of the GPZ 7000 isn’t given so much as a mention in this thread, given that it is the lowest frequency option and coupled with the 19-inch coil would be the Zed's weapon for large, deep nuggets. ?‍♂️

Lunk, this is something I want to know more about from you and anyone else that uses the extra deep mode. It seems to be the most forgotten and least used mode.

Why would you run the Zed 19" in anything other than ultradeep? Defeats the purpose. I'm sure settings for max depth for coil size were being used on the modded 5000 (still great results) .

I've had next to no experience with these modded detectors, JW has a modded GPX 4500, never uses it, but has it.  He's used it once in my presence and he had a Sadie on it at the time, I had my stock 4500 with the NF 14x9" EVO on it when I first got that coil, I found mine was more sensitive than his on small targets in some very basic tests we did at the time waving over a few pellets.  How much of that was the coil I don't know, probably most of it.    Neither stood out as being quieter or anything.  I don't know enough about the mods done to it to judge it but it was one of the big two that did the mods.

I had my old 4500 modded about 4 years ago. Prior to that, I'd owned it for 3 years. In those 3 years I found only 5oz with it. Once I had it modded, I got 6oz in the 1st 12 months. The flat-wound mono coil I used certainly added a degree of 'punch' but overall, it was way more sensitive and hit deeper. I went back over lots of old territory that I'd given up on and pulled gold on most locations. The mods have evolved a lot in the past few years and have gotten better.

SS, I'll work up a topic about this in the future, so stay tuned.

PP, here is an article by Jonathan Porter that includes why you would run the Zed 19” in the other two Gold Modes as well as in Extra Deep. It is a very versatile coil that has different applications in each mode, but the key is having the room to swing it.  But as you suggested, most operators would use it to search for large, deep nuggets, myself included.

Another good GPZ-19 coil write-up with video.

Sorry Drellim, as I don’t mean to hijack your thread here; the video that you referenced shows a remarkable signal response from the modded GPX 5000…quite impressive!

I think he is asking the detectors to get/give back to him with their mods.

Funny how back in the day Woody was given a hard time about his mods, being mocked by the Minelab disciples who believed that Minelab were the gods & how could any body else improve their detectors. Well, as time has gone by we have come to see Minelabs business model. Why improve an existing detector with a mod or two when ML can release a whole new detector with those mods for a whole new high end price. Mining the miners.
