    Minelab SDC2300 information and questions

    Also another thing that happens in the heat is static charge build up with in the electronic ground in the metal detector. As the coil becomes close enough to the ground or another object, this charge discharges to actual ground causing a false signal. When this happens trying again straight...

    Minelab SDC2300 information and questions

    Hi LC, regarding the detector shutting down, early on a lot of people found this problem. It was due to the batteries being a bit loose in the holder. I think the fix was to put a small piece of cardboard in there to stop the batteries from moving. If you have a bit of a look around you should...

    Thanks Kman! :D I am 100% serious about the 5k offer too. I won't be holding my breath waiting for someone to claim it though! AuMan PS, G.J.C, I know what you've been up to, thanks for the laugh!

    3500 v F1A4 Jack Lange stage 2

    To state that there are controls on the box that are not connected is a pure lie. If anyone can produce a genuine JL level 1, 2 or 3 that has controls that are genuinely not connected and have not been tampered with, I will pay you $5000. The funny thing is the bloke who bags the mods on the JL...

    Hi Blind_freddie, You should get really good runtime from your detector now. It is best to do it as you have done and not directly to the control box as there are other things that need to be done to power it directly(it can be done). Good work! AuMan

    Hi Nenand, if the timing clock generator works on the same principle as it's predecessors, you can have manual tune. But, it will cost you your warranty and ability to ever have it serviced or repaired by Minelab. Perhaps they could get into modifying their own detectors?! :D AuMan

    converting whites DD coil to GPX

    Hi Kman, For a start, you will need to measure the resistance and inductance of the transmit coil. It needs to be around 300uh and .4 ohms. I suspect the resistance on the gmt will be higher. AuMan

    Nice chunk of gold! Jaros, check here, http://www.vkteksolutions.com/ The treasure mate 2 would be the one you are after. I think also B&Z boosters may be suitable as well as they are powered from their own battery. AuMan

    (DIY) F1A4 Simple Mod information (hope it helps)

    Many of the class d amp modules found on ebay require 5v power input. I would not recommend running the amp from the 5v power rails in the detector as it will draw a fair amount of extra current compared to what the rest of the circuits use, drop the rail voltage and upset the stability of the...

    (DIY) F1A4 Simple Mod information (hope it helps)

    Jaycar have some screened cable,(it is the grey stuff) use the one with 2 centre conductors, that way there are more strands of copper between your switch and plug so it is less likely to break. The ground balance wiring between the red and blue wires on the switch does work, but it causes the...

    It goes across the blue and yellow wires. Make sure you use shielded wire with the shielding connected to the yellow wire. AuMan

    Well it could be a garret pinpointer in his back pocket, but most likely needs to go back for a check up and update to the latest specs. AuMan

    Hi Flashunter, Ok well that eliminates the coil then. Probably best to send just the control box back. LT, as of late January this year, Jacks L2's had variable gain with a mark for the standard gain setting. AuMan

    MINELAB F1A4 ex military metal detectors - tips, settings, questions

    Some things to try. Wriggle the coil lead where it enters the coil and make sure the detector does not sound off same for the plug end. Do you have other coils to try with it? Make sure that the detector does not sound off when you touch the metal body of the coil plug. Hold the detector...

    Hey Tm, I have heard similar but who knows, it could just be a rumor, you get many of them in this industry. I think they will only be able to buy the ones that are still to go to auction, not those that have already been sold. There are quite a few people that have bulk lots in storage. I also...

    Just an amendment to the above instructions where I said "Carefully select your spot so your drill is centered between 2 slots" Should read "Carefully select your spot so your drill is centered in the slot between the ridges" AuMan

    Ok LT, What I was referring to was your comments over on minelabmods. The tone mod is out there, that is fine. I don't care about the picture, there is no reason to remove it. You did well identifying the safe drilling areas. What I was referring to regarding drilling into the endplate, was not...

    LT, the only place a pot will fit is in the centre area where the speaker lives. As I said, there is a bit more to it than just drilling a hole, if you had drilled through these you should know this. Sorry, but I'm not inclined to give secrets away. If you figure out something for yourself...

    Mozzie, be careful drilling into the front panel if not done correctly you will rip it to bits. If you intend to get it modded at a later point in time, the holes need to go into specific positions. There's a bit more to it than just drilling a hole! I would suggest just adjusting the on board...
