It's an impressive detector.

It zaps over small nuggets as well.

Going to test it were the ground is nearly bedrock and where I have found gold previously with my
other vlf.

The trick is to get the gain as high as possible by increasing the SAT speed.
They are very impressive detectors and iv done quite well with mine the last few years.

Is everyone using earphones ? I can,t stand the darn things I seem to end up in a complete tangle of detector,cord,pick and anything else within 5mtr of me. But perhaps I do need to use them as so far I haven't found any gold.Would love to hear other thoughts on this from more experienced operators especially.
Cheers

Hey falcon I definitely used earphones. Prior to that I didnt find any gold. I ended up buying a set of jogging earphones the ones that sit on the back of your neck. I would thread them through my jacket though. Def increased my tone sensitivity. Everyones different though.

It's very hard to hear subtle threshold fluctuations without headphones, so they are a must on gold VLF's. Especially on windy days with lots of ambient noise, plus it helps your concentration without any outside distractions. Some people prefer full ear headphones to cut noise, especially during the colder months, but inner ear headphones are advantageous in summer months if you hate sweaty ears.

If you hate headphones, the other option was to run a pair of powered amplified speakers up near the arm cuff, from memory the ones some guys were using on the gmt were the small round Nokia units purchased off ebay. smile

I used Nokia MD-11 speakers when I had a GMT which I found had better audio than the stock internal speaker. The MD-11's have a built in amplifier & run on 3 x AAA batteries. Cost about $10 each. You can hook them up together to get a dual speaker set up or as many as you like. Each one has a socket to plug another one into. Downside is they don't have a volume control but I thought they worked well.

Photo of my set up before selling cry Still see spots where it would be nice to have it. You could easily set them up to attach onto yourself if required.
Edit: I have these attached to the arm cuff screw on either side. They fitted there nice & neatly + weigh nothing that would worry your days swinging smile You also need a 6mm plug to 3.5mm socket adapter - about $2 or $3

My old GMT was giving me a little trouble with bad ground balance. In desperation I called goldsearch for advice. Dean suggested checking the connections and giving the motherboard a clean. Sometimes dirt gets in and causes a bad ground balance alert. He even offered a loaner coil to test it. I don't usually write recommendations, but these guys went above and beyond. After reading some horror stories from people seeking help from the US I can only give these guys a big thumbs up!!!!!!!

Yes I would agree......I set my SAT nearly up full and increase gain till she starts to chatter in the hot ground, back it off half a turn and spot on!

The threshold hum from the fast SAT recovery is perfect and at 3/4 noise I can hear the slightest change even with no headphones in the middle of the bush.

The best VLF on the market without a doubt wink

I gave my minelab x-terra to the kids for coin shooting.

Only drama by memory running the SAT speed so high like this is the iron grunt isn't as good, yes they are excellent detectors

Hi GMT Bandit - Looking to get started and noted this thread. A little dated but wondering if you persevered with the GMT and how you find it. It looks like a reasonable entry level despite taking a while to tune and get used to. Anyway if you're still on the site or if others could let me know that would be a great help.

It is not an entry level machine, It is the top of the line machine for fine Gold, It has served people well over the years, There are newer higher frequency machines that have come out since but it GMT can still hang with them all, Since this thread was started 2 new machines have hit the market which is good but they all find Gold and every other thing in the ground too, The birth of better PI machines has had an impact on such machines but these Hot LF machines can still find the Gold and will for a long time yet.

That's what it does, If you push the trigger forward it will make a sound like a Goose farting in the Fog when it goes over Iron.

There is No such thing as a Gold Only machine, Gold Is metal and that is what it see's put a Nail on the Ground and a Gold Ring then push the trigger forward and then listen to the Machine and read the Iron Probability meter and Dig all targets that read below about 85%, Ok.

You will have a hard time if you think any detector will tell you indefinitely what is gold vs junk. Its a metal detector learn the manual read it thrice dig every target its a great gold detector enjoy.

No worries mate, Even the most expensive machines see metal and not Gold, The skill comes to those who learn their machine well, You have a Machine that is meant to find Gold and it surely will find large and small Gold but it will also find other metals and then that is where the skill of the user comes in to play, Don't give up, Practice different setting and sweeping the coil over different metals and you will hear soft sounds and sharp sounds along with broken sounds and some spongy sounds caused by hot rocks etc and with the Trigger forward you will hear the Goose sound or like a Pig Grunting and that is Iron based metals that you do not want to dig, But if it makes that sound and the Iron meter is reading in the low 70's/very low 80s and below you might want to dig it just to be sure because Gold that is Iron stained can make the Iron Grunt sound, that's where the practice comes in, You have a good machine there so stick at it, Ok.

Good luck,

John.
