White gmt goldmaster

putting a order in next week or so with goldsearchaustralia for a whites gmt, those of you who seen my videos on this forum will know i been swinging for 2 months now with a garrett ace 350, i love this machine it goes everywhere with me but sadly it cant find gold in my very rich gold area. i can reach coolgardie/kalgoorlie within 2 and a bit hours from my house, southern cross/bullfinch within a hour and the 1911 goldfields around westonia within 30 minutes. yet each trip ace 350 is finding coins, some as old as 1882, a pocket watch from 1888 made in new york. so is finding great stuff, but i got gold fever, had it almost a year and it will kill me soon if i dont find gold. so happy to buy the gmt, have watched a few videos and read a few forums, its iron grunt is good to search old heaps that pi users avoid due to old nails and iron rubbish in them. plus it can pick up small gold in the fields which is all good. am after some peoples stories/ advice on how they going using it? i have read a couple pages on info on how to tune it down to search salt areas ie beaches, which i will try on salt lakes as i got a lot of salt lakes and some riddled with nuggets that i seeing my mates finding using their minelabs. so want to get it out on the salt, even try to use it on some coin/relic hunts, my daughter loves using ace 350 but i dont give her much use of it now as its my only detector. so with gmt in my hands she will be swinging the ace around. so yes would like to hear from other gmt users on how you going with it

have you done a search on this site for the whites gmt detector.

some good pro's and cons for that machine vs a minelab 2000.

I bought a GMT last year as a VLF addition to my two PI detectors. Previously I had a Minelab Eureka. I detect in an area of magnetite and laterite which the Eureka could not handle (PI's can dull the laterite responses but not the magnetite).

I did a fair bit of solid learning/testing when I first got it. It ground balances very quickly. It seems to "learn" the ground as you go and will start to cancel out more and more hot rocks & laterite more quickly as the day goes by, especially if you use the "GRAB" function to record this ground type from time to time.

The iron grunt is great but seems to get confused if the target is perforated and rusted. Wire & nails are discriminated easily but old pieces of tin often show as a non-ferrous on the display and by the tone.

I bought the GMT to detect in narrow gullies with lots of black sands, that have produced grains of gold by panning. So far it has not picked up a gold target although it has scored small pieces of very thin wire from around 4cm depth. I have a 0.4 gram nugget (small ball shape) that I use to test/tune my detectors on location. I must admit I have been disappointed with the sensativity of the GMT on this target and I actually need to have the coil almost toughing the slug before it will respond. Watching the videos and reading the reviews suggest the GMT should scream on such a target, and this was the reason I purchased the GMT. It has reacted like this since day 1 on this target, no matter what combination of settings I try. The PI's (GP3500 & GPX4500) boom on this target, even with larger coils.

I am contemplating having the detector sent in for a check-up. Does anyone know who/where to send it to in Australia for a service/performance check? It was bought from GoldSearch Australia. I am based in Far North QLD so I wondered whether there was a closer service centre?

Cheers.

G'day Tuflux.

yes if you have questions tony at goldsearch australia will help you. placed the order today for gmt with him, i got heaps of mullock heaps, tailings and mine soil from the shaft around them. i got told on whites forum its best to send gmt to detect that, take a rake and shovel. slowly work through the pile to find the smaller bits of gold they missed a century ago when digging shaft.
Tony is great man, he also said he got some setting info from a man in northern territory on how to tune the machine in that soil. so he mailing that to me with the detector. glad i spent the extra 200 dollars to buy it in australia, have a aussie to help me detect tune it etc here

Greetings all - first time in forum !
I agree with Tuflux's comments about the GMT - I have had one for a couple of years and have been frustrated with getting it to settle down and track targets. I sent it back to Tony at Gold Search to check to see if it was tuned correctly from the factory etc - but it came back ok. (very happy with his service, by the way - very obliging.) The field reports read great, the instructional DVD makes it look easy and users in other forums praise its performance, but I just haven't cracked it yet !! And yes, I too have had the frustration of trying to make my 0.5g sample nugget stand out from the noise around it. Anyway I am happy to persevere but would love to hear any information that will help me find some gold with it.
I read somewhere that it helps if the lead coming from the coil is taped straight along the bottom shaft rather than coiled but the DVD doesn't show it - anyone got any theories ?

I emailed Tony Mills, and Tony suggested sending the coil down to him after hearing of the symptoms. On my first outing I could increase the gain well past 7-8 but the threshold became unstable. On later trips, in a different location, I couldn't get the gain past 7 without the detector reporting "BAD GROUND". I then noticed I got the same error, even if the coil was pointed skywards.

Anyway the coil is on its way to GoldSearch so we will see what the verdict is.

Gidday Tufluxs Greeting all. I also live in FNQ and bought a GMT of Tony at Goldseach and I am very happy with it. Found gold first time out with it, in fact I was walking along a creek and got a good signal I then asked the wify who was following behind with a SD2200 with a 8" mono to check this out and after waving her coil over it said it was nothing and walked on. I sayed and dug out a little nug stuck in a crevice. I later found the 4500 with the right setting also gave of a good single and a terra 70 only gave off a signal like a ground noise, not a positive signal. I read the new fisher VLF detectors are very good ,has any body out there compared the new fisher gold bug or F75 next to a Whites GMT?
Cheers

Good to hear GGold. I thought I may have been conned with the GMT but the more I read, the more I believe it should be a good addition to the arsenal....as long as the coil is fixed. I thought I might buy a second smaller coil from Tony as well as a backup. What size was the nugget you found in the crevice? Cheers.

HI Tuflux, Hope your coil is the problem, if you live close we could have worked out if it is the coil or the control box by comparing machines ect. I was also thinking of getting a smaller coil at one stage as it would make it even better on the tiny targets but for now I am quite happy with the the coil it comes with as this is the best all round coil. The first nugget I have found with the GMT I do not have a set of scales so I can not tell you its weight, but it is a small flat nugget found on its edge in a crevice and its a bit honeycomb shaped, not solid. So thats why the earlier PI machine can not get a signal from it. To sum it up the GMT is a good machine to have to compliment the PI machine to help find more of the yellow stuff. cheers

well it should be here by middle of the week, then not next weekend i wont gold detect as i focused on the avon decent, they call it the worlds longest white water race, i call it the worlds largest coin shooting race. i will coin hunt in northam, katrine,cobblers pool and toodyay for a week chasing coins with garrett ace 350 or give the gmt a go at coin hunting might find a ring. i buying in a week a garrett gti 2500 to use for coin shooting/ relic hunting its coming to me with a 14inch dd, 12.5 and 9.5 image coils that are not dd.
found today with ace 350 a 1885 sixpence, a 1888 penny and a 1896 penny in merredin, plus 7 one cent coins 1966 to 1973, 2 two cent pieces from 1980 to 1981. so a good coin hunt today

Got the replacement coil from GoldSearch yesterday. I noticed the new coil has a much shorter cable length than the original. I remember reading that cable length can be critical to a coils performance. Anyway, a quick test in the backyard showed I had full range on the gain control and could ping a 0.1g nugget from within a couple of cms. Gonna give it a go in the wild this weekend.

finally got home on wednesday, gmt arrived a week before that but i was away from home. tried it around parks and ruins here, its working great on finding coins. off to goldfields in a few weeks, see how it goes. I also picked up a SD2100 modified machine as well this week. is missing a 14 inch coil. so having to pick that up next week from prospectors patch, $70 for coiltek DD 2nd hand. so will use both machines gold hunting, see how they go.
