Garrett Pro Pointer .

I have a Garrett Pro Pointer but have not used it much . Looking for some feed back as to how good it is to find specimens ? That is quartz with bits of gold in ?

G'day Mike

By detecting/scanning over piles of quartz rock, in the hope of pin-pointing out gold within a quartz specimen, is pretty much useless & very time consuming using only a hand held pin-pointer. Pin-pointers (less the ones scanning a quartz specimen being moved around in your hand), cover very little portions or section of your host rock, when just scanning over quartz rock at random. That's what high frequency VLFs are good at, for the quick and thorough coverage of scattered gold bearing quartz piles, found out in the goldfields.
Even though gold, may not be visible from the outside surface & buried within the specimen, as long as the gold in the specimen is of detectable size & within reach of the pin-pointers field of depth, it should sound off.

Cheers Kon.

The only detector that I have got now is my Minelab Explorer . Would that be better than the pin pointer ? Of the " cheaper " detectors which do you think would be the best ?

Coupled to the smallest coil available for it, may be. The explorer is a Broad Band Spectrum detector, automatically transmitting multiple frequencies simultaneously into the ground. Perfect for coin Identification, but not exactly what I would class as a single high frequency detector, such that of a Fisher Gold Bug 2, transmitting a single high frequency of 71KHz.

Cheers Kon.

I agree Kon. The BBS and FBS range do not have very good small gold sensitivity.
The Gold Bug 2 is fairly good and the old Scorpion Gold Stinger has a calibrated TR  setting that can locate very small gold in individual rocks when used correctly. The Whites Gold Master range operate at 48khz and are good on small gold but they cannot handle very high iron mineralisation and penetration in extreme iron minerals is only a few cm.
The falcon 20 pinpointer is also sensitive to almost invisible gold.
Just an opinion, Not gospel.

Thanks for your replies and advice . I did look at the Falcon before buying the Garrett a few years ago . I bought the Garrett to pin point coins in the grass . I think the Falcon would suit me best , getting a bit old for using a detector for long periods of time . The Falcon 20 is AUD$400 + .

After a number of months of doing nothing , I decided to build an impact mill using chains in a drum . The local scrap man will sell me off cuts of RHS etc. at $1 per kilo . I have got the drum and end plates and have made up the inlet chute . Making it modular so that I can dismantle it and put it in the back of the truck . I have got an engine to drive it . Armstrong Industries make a good one but they are $6 k.
Will keep the forum updated when I get more done .

Good stuff Mike, be interesting to see how it goes.

I have used this one from Armstrong Industries, it worked well, it's there smallest model, it liked quartz species better than Ironstone ones, which had to be feed into it much slower than the Quartz ones.

   That's interesting dave ,didn't know about there smaller model ,its a ripper ,on their website they say not all generators will run it ,surely a 2kva would ?? only being a 550w motor !! ( couldn't get any sound on my computer ? ) do you use it much as a form of loaming / sampling ? sure beats a dolly pot

This Falcon 20  pinpointer has been around since God was a boy and it still fetches a high price, so I guess it works fairly well....when used correctly?

G'day Hugh

I just ran it from the 240v power point at home no worries at all, it belongs to a mate,I just borrowed it and I put several KG's through it.

Just used it for crushing, you still need to break the rock down to like marble size an feed it in slowly, and I does a good job. Your right is way better than having to dolly the rock right down to powder.

cheers dave

That is a nifty little crusher and you only have to make approx 2000 dollars in gold before it and the generator have paid for themselves..
I wonder how long the crusher will last.

Can anybody do a mod. on a Garrett Pro. Pointer and make it into a Falcon 20 ?

No!
I think the falcon runs at around 300 khz??
