Hi Esky, The audio socket on the battery itself doesn't have an amplifier. That socket is intended as a backup if something were to go wrong with the receiver. You can plug a Wazza's Eyespy directly in to the battery on the side of your detector and still have audio from the receiver. The...

Hi Goldchaser, Sure is plenty of oomph for driving a speaker. And the receiver lasts for a ridiculous amount of time running said speaker. I designed them this way so even in years to come the receiver won't let you down by lasting less than the battery. Cheers Mick

Hi Redfin Does it? Nope, certainly no acquaintance. Sure, I know him, but I live in my world and he in his ;) Thanks Reg and Eski! Those who have been around the forums for a long while may know me elsewhere as Mechanic. The website is still getting updated and ironed out. Cheers Mick

Mbasko is correct, the third pin is not connected. It is actually quite safe to pull a bit on the ground balance lead. Minelab use a very special wire for the lead, and it is REALLY tough! To repair your lead, I'd just put a small dab of superglue on the thread part of the plug and slide the...

Err, pardon me butting in here: When using a mono coil, never use cancel. It can only be useful with a mono coil when pinpointing a large target. When using cancel with a mono coil, you receive about 5% signal. The detector should be dead quiet if using a mono in cancel. In built up areas, use...

Ironrock, it is hard to fathom, but that is just the way it goes. If that specci was crushed and pressed into a more solid lump, it most likely would be detectable and probably at much better distances than it currently is. AuMan

Good luck with it! Sent you an email, check your junk folder.

All of the mods can be turned back to their standard settings, so if it all turns to crap, you can go back to standard and work your way up from there. As for depths, it is hard to quantify. There is a real improvement and it will amaze you at the depths the little tiniest bits can be pulled...

The 4500 could not detect it at all! It is because the specimen is not solid. There are so many fine individual details(and conductors). The eddy currents induced into it would decay extremely fast, too fast for a standard 4500 to pick up. Also some of the eddy currents would cancel others...

I think that may have been similar to the gain in the level 2. It works, but ground balance can be a problem in hotter ground. The level 3 has a very different gain mod, with a host of other things done to minimize the ground balance problems that came to light in the level 2. AuMan

Hi Ded, The 45 does have more timings to begin with. When cranked right up, it is pretty good with the sensitivity to smalls. You have options such as the stabilizer, back end gain, manual tune and different audio modes such as quiet. Personally I'd probably go for the 5k over the 45 as there...

And here is the 68g specci that is only detectable at about 1 inch with an F1 L3 or SDC. No response from a 4500.

The other thing to keep in mind is the make up of the nugget. If it is solid, that is one thing, but if it is prickly with lots of folds and fine detail its detection distance will actually be a lot less than expected. A customer in the US found a sweet specimen last year and left it in acid...

The tone is quite simple, there is a lone trimmer on the audio board. Use a 50 or 100k pot in its place. The gain however is done on a double sided 4 layer board that gets attached to the main board along with a bunch of other stuff on the main board to make it work properly. Sorry, no...

Tell me about it!! And then when you do have time it is 40c or raining!

Hi Muk, PM sent. Eski, these F1's still amaze me! Was testing out a modded(by someone else) 45 that was sent to me for repair. After the repair and some adjustments, the 45 was running quite nicely, however, the f1 level 3 still had it over the 45 for ground handling, sensitivity to smalls...

Hi Firey, Some coils work great, others not so great. I always found that the commander coils left a bit to be desired on the F1. They are ok for standard settings, but once you start to increase frequency and gain, they can cause the filters to overload and make the detector seem somewhat...

level 3 for 1200, bargain! Does that come with the li-ion battery as well? If you have any doubts about the machines performance I would be happy to take a look at it as long as return postage is covered. There have been a couple of small tweaks to the level 3 in the last couple of years. AuMan

I think the F1A4 is a brilliant detector! In the standard form, they are ok ish, but level 3 mods(The Jack Lange definition of level 3, not that other bloke ;) ) are what make these detectors truly shine. They are very immune to nasty ground(when set up correctly) and can perform just as well...

Here you go. The pinout for an sd/gp power lead. Enjoy! Auman
