Minelab repairs and modifications, i have been detecting since 1980 and found hundreds of thousands worth of gold nuggets. I build highly modified detectors so to give prospecting a greater chance of life changing finds. I make the worlds best detector technology better. So you want to find gold, you better know what you are doing or you will never find the big deep ones. #metaldetecting #minelab #detector #bestmetaldetector #Detectormods.com
I have inherited Grandy’s SD2200d. Been wanting to reach out to you for a while now. Been saving up to send it over for an upgrade. Be neat to see a DIY upgrade video. Yes please. I would like this
I love the mini-series idea. It would be nice if you do some benchmark noise comparisons before you start the upgrade. That way we can see the before and after results. I own a couple of these older SD2200-V2 and SD2200D that I bought used. I have played with them a bit and I couldn't tame them at all. I suspect they both need these upgrades, because as the sit all they are is noise makers. I have no idea what the controls are supposed to do. I have been following this channel hoping you would do a series like this.
Hopefully there's still a bit left in your bottle or not much productive works going to happen today. My votes for the 2100, would this make much of a difference if its ie 2100d compared to one of the other 2100 in the series, or would they all be compatible to the mods. Cheers Craig 🥃
G'day Woody, i have a modded 2100 (by you quite a while ago). I'm happy to bring to you for your show and tell project. I come in to Ballarat on a regular basis, and I am happy to leave it with you as long as you like 👍 Cheers Andrew
hi my name is MikePerry ,I am a 72y/o pensioner detctor owner with a sd 2000 minelab detector and would love to have my detector upgraded. If selected where do I send it Cheers Mike
As an Electronics Technician myself, your references to various aspects of components slowing responses or reducing responses (capacitor wise) make sense. I also see the advantages of producing "matched" chipsets and other associated components. I will be most interested to see the field test of your current iteration. If your historical archives go back to Whites 6100/Ds, I would be most interested :)
They buy a 6000 then run 100 ohm crap head phones with them i run my own made headphones 300 ohms on my 4500 and have great results.The drivers are expensive 300 ohms .
Hey Woody, the problem was keying up on CH 27 UHF CB specifically. I managed to rectify the issue through shielding and the .1uf capacitor idea. I have been doing many upgrades and improvements mainly based around grounding and shielding etc that has my detector now running dead quiet in bogenes I have to keep checking it's turned on. With all your mods and me being a little being overly fastidious about electrical noise, targets now jump out very distinctively. I remember mentioning to you about replacing the capacitor with a lower tolerance one and see you have gone for a larger one. Can you please explain the benefits the 10,000uf capacitor might give this detector? Also, YES, shield those power transistors....I made a conductive (metal) cover that slid over them as low as I safely could and grounded it. Thanks again for your superb technical videos.
The more shielding the better imho, increasing that cap gives more headroom to keep the transmitter output stabile, especially as those types of capacitors dry out over time, heat and heavy currents passing in and out.
looks like a great mod woody i run in sp extra then its a return short signal i dig down 6 inches then go into enhance to test the target ,reducing the ground noise in sp extra or even normal mode is a game changer .A good 4500 operator knows those wide band long ground noise signals are not targets but removing them would help in a big way buy stopping the need to dig so many suspect signal's.
