General Discussion / Re: new mod settings on 4500

« on: December 05, 2016, 10:48:41 pm »

I like the 20" mono its a good coil, i use to walk around detecting with it lapping my swing about half the coil. Than realised one day i was only giving my self only about 50% chance of hitting a big nugget at depth by doing that. Now when i use a big coil like that, i only increase my lap by a quarter or 1/3  so i dont miss anything deep at the narrow end, hey good luck in Q hope you find a bit.

I was talking to George from NQ miners den some time ago about 5k clones showing up. He told me a bloke walk into his shop one day asking George to sell his 5k clones through his store. I had tears from laughing so hard. You'd find more gold swinging a whipper snipper!

General Discussion / DIY coils

« on: November 28, 2016, 06:33:09 pm »

Gday all, i am planning on building my own coil. As its been stated before by people in the know, the quality of build can be improved on over current version available, as something thats hand made can be done with more precision and care. I have no experience with such things i am drawing my idea's and technical info required for such a task from what is already shared through different prospecting forums by many.
I recently tested the 15" detech on my gp3500 and was surprised at its sensitivity and punch it has on both small and large targets in what i call hot variable ground. I like to make an attempt to replicate
This coil in a 11" and maybe a 18" version for my "own personal use" using my old coiltek dd's i have laying around for the builds. Who's had a crack at making their own coils and how'd they turn out for you.
Regards joeboy.

Hi Peter, yeah i would like it to hit a bit deeper. There's a few of area's I'd like to go back too that produced some nice lumps, Where the ground was deep and extremely noisy even running the 45 in enhance. Getting my 35 to handle ground better with extra depth would be main objective i think. My main coils for use will be dd's. There are so many different mods developed by you over the years, i dont really know what mods to ask for that will best suit my needs on the gp. The variable gain sub board is a must, i assume some old components in the gp would have to be brought up to speed aswell. So I'm thinking not going the full upgrade, somewhere around the midway point. If you could Pm me, an idea which upgrade would suit my needs and price that'll be much appreciated.
Cheers Joeboy.

Information on the new developments / Re: Can a GPX Series detector perform any better than a GPZ or SDC ?

I think the new 45 is identical to the 5k just no fg! Just my opinion tho im no expert, it balances fast like the 5k and just as smooth. So i cant imagine the two 45's are the same machine with identical components internally.

Well if anyone would like look for them selves 5k vs 'old model' 4500 on deep big gold, you can find the video under Budwhiskers on you tube. I wish i had the older 45 now not the new one.

Gday woody, I've got an opportunity to pick up a gp3500 pretty cheap,
I was wondering if the new developments with mods would work well on the 3500. I was thinking of selling my 45 for basically the same price i bought it for and getting the 3500 modded which would free up some cash to get it done sooner. I'm not a fan of fine gold or enhance. Will the 35 accommodate the latest mods ok.
Cheers joeboy.

I was just watching a youtube clip tonight showing the difference between normal vs enhance and fine gold. The video was clearly demonstrating the power of normal timings, tho there was something that cuaght my eye. The test was a Gpx5k and a 4500 using the same coil 22" mono over the same target which was a 31 ounce nugget at 2ft and clearly the 45 was thumping it in alot louder than the 5k which the guys making the video didnt pick up on. Reading your post woody on the differences between the 5k and 45 now makes alot of sense

Hi everybody, for those that still have a modded sd2200 could you chime in and give me a run down on how to use the mods ie: (m.s.d) & (m1.s.m2) and is there a special start up procedure involved, like turning the machine on in a certain setting! Any info is much appreciated.

Thanks woody, when i open it I'll check the input voltage wirrs first. Other than that is the bipolar transistor easy enough to replace and is it available to buy from somewhere

Gday woody i have a sd2200 that fails to turn on, wondering what could be the cuase of this problem. The carboard minelab box was exposed to water with the detector inside, Tho the control box wasn't directly exposed do water there would of been alot of moisture around it over a 2 day peroid.
Its not a standard model, it had the full upgrade done by you some year's back with variable gain mod also. Its my brothers detector and he's not prepared to spend more money on it, so its getting sent to me. Im going to open it up for a look and see if there's any obvious signs of damage. I found my first gold nugget with this 22, so I'm hoping its only a simple part to replace, any suggestions would be greatly appreciated on which component might of failed on start up and what to look for? assuming it did fail when turned on.
Cheers joeboy

 I like the 14 mono really go's nicely on little bits
and has no problem punching deep on bigger stuff, great all rounder for me, hey Ron if you haven't got the 18 elite try and get a loan of one for a day or two, If you like swing bigger coils mate, the 18 elite is a gem in my books. I haven't had a real opportunity to use it much due to its size, and the area's I've been going, tho we have a test bed we use to check out new coils with, and i was shocked how much more depth it had over any other coil I've owned. including my old 18 mono
