I managed to get one of these 2nd hand for $300 AUS to start my prospecting journey. Never had any experience with detectors before, and I've only been out 3 times so far and only found nothing but junk. Still trying to get my head around getting it to work properly. Living in bendigo VIC i'm not short on having placess close by to go and have a hunt.
I bought it because it seems to get very good reviews and it a nice beginners VLF machine. Lets hope I can have some luck with it thumbsup

It is indeed an excellent starter machine at that price and you will learn a lot from mastering it. Work very slowly and keep the coil on (or as close as possible to) the ground. Seek out areas of old shallow diggings and work in or close by them, keeping a watchful eye out for rocks, bushes and fallen branches that may have impeded others, but could be sheltering undetected nuggets. If you're finding tiny targets (shotgun pellets especially), you're doing it right.

Best of luck. thumbsup

thanks mate a bit of luck would be handy. Mainly only finding surface junk at the moment and also chasing my tail on hot rocks and false signals haha. Im digging everything just to make sure and also just to learn noises and what not. The guy I bought this off said if you really get into it this machine wont be the last one i buy. I hope to buy a cheapish 2nd hand pulse induction one day in the future, but i plan on funding it from gold found with the GMT wink

I've got the GMT as well and while I haven't found any nuggets (not a lot of detectable sized gold around where I live) I have found enough shotgun pellets/lead which has a very similar sound to gold to know that it'd definitely work just as well in finding the gold nuggies if you're in the right area. Trick is training your ears to distinguish from genuine targets and hot/cold rocks... and best practice I could recommend is carrying a few bits and pieces of lead/metal bits (of varying sizes) and put them in various types of ground/soil (preferably where gold has been found) and get accustomed to the signals they give off at different depths/sizes.

Typically though, a good signal will have a quick/crisp zip zip sound whereas hot/cold rocks will be more of a drawn out and inconsistent "howl", for lack of a better word.

As for settings, you'll need to do a lot of experimenting yourself in the various areas you go to, but I think most will agree that you shouldn't use the auto-track feature (keep it on manual) and do the ground balancing on a regular bases yourself, and also the recommended gain setting (marked) is probably a bit too high for most Aussie soil... I think perhaps a setting of 5 is more suited most of the time... but I'd recommend reading up on others recommendations as much as possible to get a much better starting point -- been awhile since I've used mine.

Also headphones is a must in my opinion... most the gold you'll be finding with this thing is likely to be very small and for the most part you're only going hear very quiet/subtle change in pitch -- so you'll need every advantage in hearing as you can get.

Good luck! thumbsup

I keep the gold fever at bay with the help of my SDC 2300, Walbanker (thanks Wal!), 6" Mini Highbanker, and assortment of pans, sieves & tools... plus a bucket load of persistence!

Just curious has anyone here had much success with the GMT in the bendigo VIC area with gold finding?

I hope so, I've got one too that I need to get over some gold at some point. It finds shotgun pellets no problems in central Vic soil so gold should be easy. Just haven't spent much time over gold yet, coins and relics are too much fun for the minute!

I'm having a hell of a time trying to figure this machine out. I'm only new and have been out only half a dozen times but im starting to get a bit frustrated and disheartenedwith it all.
I got gifted a little piece of gold (roughly the size of a match head) that i keep in a little container that i use for reference every now and then but my GMT doesnt pick it up half as much as I thought it might . So with how much noise this detector makes I cant decipher what is just pure ground noise and what is a potential target. It's like 100 mosquitoes are buzzing around my head and trying to listen to the right one.
I'm going to persist with it but my word its starting to get to me, I dont think ive even found a target that has been in the ground yet, just surface junk. I feel like half chucking it in and going to buy a Pulse induction machine.
any tips would be awesome, cheers

Kicksome, try and give yourself some time to get used to the machine. All VLF machines are 'noisy' in highly mineralized soil. The GMT is a small gold specialist. Gold in crevices, tailing heaps etc. It will not punch down deep like PI and it will sound off on hot rocks, cold rocks, iron stone etc. Key is to 'balance the machine. What I mean is there is a spot in the setup balancing the ground, just enough gain , SAT, sweep speed etc to best match the conditions where you are hunting. You can run the machine smooth and quiet by lowering the gain, or go hard and run it hot. Smooth and quiet is best in the long run, I only run hot to check a spot that has already produced gold since is is noisy and difficult to maintain focus running hot. Set the machine up to run as quiet as possible to begin with until you have more hours of experience. Check out some to the GMT videos online for hints etc. The GMT is a great VLF but personally that 48 khz runs too noisy for me, that is why I went with the MXT, after comparing both. At 14 khz the MXT does not have that deadly small gold ability that the GMT has but it runs smoother with decent ability, my opinion only.
The GMT user really needs to read 'The Complete Unabridged Zip Zip' book by Larry Sallee, an excellent read which makes you a better prospector regardless of which machine you swing. Yes I do have the book and I live in Melbourne, send me a snail mail address via PM and I can arrange for you to read a copy. If after roughly a hundred hours, or when you feel you really know the machine then maybe you can make an educated decision about the GMT. Many people use a PI but keep a VLF for backup, it has its uses but in hot ground VLF's are much more difficult and in really hot ground can drive you nuts..
All the best,
Karelian

Thankyou Karelian for the nice reply, and thanks for the offer of the zip zip boo I'll try and find it first before I resort to snail mail smile
Indeed I need to send a lot more time with the machine and how to learn it. I'll go with what you say and try to run it as quiet as possible, I've been on the other side of the spectrum and running it hot for more sensitivity and depth. Which is really just probably confusing me more.
At least now I have a good little sample of gold I can take out with me and put it a couple inches down and setup the machine to bet suit those conditions.
In saying all this I might just keep some money aside for a PI machine just incase. Just seen an sdc2300 for 1800 on Gumtree, good little machine for a noob like me

Had one, it's sensitive but very noisy, also susceptible to EMI. One mistake I made is I used a smaller coil too much, if you have one, just use the stock coil. If meteorite hunting, use the 14" elip.

The GMT is a hot one for sure but with the right coil the MXT will see bits easily down to 0.006 grams and smaller if they are on the surface, trouble with hitting targets that size is finding them which is a lot of time wasted,
