Gold bug 2 v White's GMT

Post  dirtdiggin on Wed Dec 24, 2014 1:07 am

Hi all

I'm just wondering which of these Whites GMT v Gold bug 2 are best for finding small and large gold?, and which are best for both small and large gold as well as being able to find eg rings and coins?
Thanks so much for any advice.

Cheers Brett

Both these detectors will work in our soils, the GMT tho has the edge due to not overloading as bad in the more hotter grounds.
Both will find large and small gold if you know how to put the coil over it. Thats the tricky part, which no one is really going to be able to help you out with.
The GMT has a few tricks up its sleeve with the ability to ID iron a little better than the disc mode on the GB2. Knowing the level in which to set detectors having a disc mode is challenging, and often we get it wrong when making that decision. The GMT will grunt over iron, and it works pretty good, but the level in which you set the sensitivity/gain can see it grunting with nearly every step you take in really hot ground.  Easy fix, find ground thats not so hot....if only it was that easy than both models would be on a level playing field.

The GB2 will ping very small bits of gold, but in order to get it to do that, you have to get the sensitivity set where it can handle the ground, and while i found that tricky at times, it can be done but the tendency for it to overload was more frequent, and hot rocks become very annoying. Height above ground and swing speed come into play here on both models. Saying that, the GMT was only a little better but it has a trigger you can pull for sorting out hot rocks, which is something the GB2 hasn't got. How reliable is it.?? How long is a bit of string?.....on the the surface its pretty reliable, and thats only because you can see the problem rock...under the surface your gunna have to dig to find out. When the trigger is pulled for the summing of targets, the sensitivity drops, and on some deeper targets, the signal is very week in order to get any useful information. If you up the gain to compensate, you up the gain also on the ground round the target as well. Sometimes you can get away with this, but most times your going to have to dig it to find out. Both have difficulties iding to any real depth, but have no trouble finding targets at depth. Keeping that in mind, you set yourself up for shallow detecting and both will give good results if you remember that the soil plays a big part in masking the abilities of VLFs to id with any real accuracy. That pretty much sums up most VLFs, but these two given their sensitivity means their more susceptible to false readings in nasty ground...especially ours.  

Both will work on coins, the GMT has the edge again here due to having a visual graph that works by giving you a segmented read out of ferrous vs none ferrous. Iv used my GMT on coins and was rattled at how deep it can actually find coins, especially old penny's. Never used the GB2 as a coiner so cant comment on its ability as a coiner. What i can comment on is both ping on the smallest bits of tin/foil/iron far smaller than any PI detector iv used. And both find decomposing cigaret foil that crumbles when you try to retrieve it, to the point that its hard to identify.
The GMT is more problematic used as a coiner because you cannot set it to disc out unwanted iron, you simply have to listen to it grunt all over the place if your using it in a park or backyard as a coiner when used in iron ID mode. The GB2 you can up the disc reject to knock out a lot of that annoyance.

Both these models have the runs on the board for being top little gold finding VLF detectors.
The GB2 runs on 71khz, the GMT on 48khz, both are testy little units to get gold with, but if your prepared to put in the time to learn the one you chose, you'll learn alot along the way about the ground you intend to use them on, and their abilities in our soil.
While there are many doing ok with these models, they didn't just pick them up and know all there is to know.....they did the hard yards.

There is a hell of a lot more to know about each of these models, but iv touched on my view of using both here in NSW goldfields and the GMT in WA soils. Both have good features, but VLFs are moving along in terms of features and usability in our soils.
These two models i think will always be considered as top shelf due to their sensitivity to small gold...and that gold will never run out in our life time.

Top notch reply there Narrawa T06

I'll add that i have tried my GB2 on coins and i lasted about 15 minutes, the misses was swinging her 705/9" concentric combo
and left me for dead in that 15 minutes while i was frantically but definitely goin full loopy with the trash it couldn't handle,
even in the Disc mode.
There was no option left but to put poor little "Rita" back in the vehicle and share the 705 for the coins, every teeny weeny
bit of tinfoil and decomposed smoke packet foil that you get in a coin spot did me in real quick and ive got a thick skin for junk.
Again the age old question of "which detector will do both well" pops up and the simple answer is NON of em.
For under a grand you can get a good s/h GB2/GMT & a good s/h X-Terra 30/305 and that would suit both scenarios.
Picked my GB2 up for $400 and i know of a X-Terra 305 goin for $210, so for $610 your in the paddock fully armed.

Whites GMT v Gold Bug 2

Post  dirtdiggin on Thu Dec 25, 2014 1:28 pm

Hi All

Thanks so much for all your help, as knowing nothing about detectors myself
your info and personal knowledge on these detectors is invaluable to me as i can't afford
to waste time and money. Once again thank you so very much.
Cheers Brett
