Gold Spear

Recommended Posts

That is going to be a hard thing to find if there ever was one. Other than trying to contact the manufacturer at the link posted previously you might try contacting Pro-Mack Mining. If I recall correctly they were the distributors back in the day. Maybe they have some parts in a corner somewhere.

I contacted the manufacturer.  They said all parts and inventory were cleared but they may have another newer design coming.

Not looking to buy a new one though....Like I said it is just a fancy VOM ...

I guess I will just have to try to make my own probe tip... someday..lol...I don't feel too much urgency but it would be useful in beach mining.... I think??????

I heard of one gu using a clam gun to find black sand layers... heard it did ok for him, but of course limited to the depth of the clam gun which is about 30 inches.

There was an old method where they drove rods into the sand and connected them and were able to find conductive layers... Kinda like the old nightcrawler system in reverse I guess.

If it can see fine gold, sluice style stuff I know a place to stick it where there is a good layer of black sand with a lot of fine gold.  I was gradually hacking away at it with my sluice last summer 🙂

Would be a handy gadget if it can.

Yep...that's the idea of it..... http://www.metalldetektor.se/gsmethod.htm

hmmmmm, I want one! 

There are many good things to say about Goldspear, but here we will only mention that Goldspear is the only instrument in the world that is especially designed to find goldflakes, small gold particles and micron gold, even in highly mineralized sand.

Unlike all other detectors, Goldspear is totally uneffected by mineralized sand. Even highly mineralized blacksand beaches or riverbanks e. g. There, Goldspear will find even minute gold particles with ease.
 

Would be the perfect gadget for finding where to dig in the river for my sluice 🙂  Also that sea beach down the bottom there with the gold in the sand!! 

Seems like you got a sweet deal on it.

An interesting device (and idea) but sounds like it won't work in most prospecting sites.  There are (expensive) resistive scanners available, that supposedly find voids, objects and minerals, including gold, in the ground.  These generally require the user to pound multiple probes into the ground; and the results are shown on a screen.

https://www.metaldetector.com/drs-advanced-resistivity-scanner

I have no idea if they are of much use in finding ground with small placer gold.  I suspect not, or we'd be hearing more about it.  But then they are expensive, so not really suitable for the detecting done by most hobbyists.

As to the Gold Spear, I wonder if a detector-based "probe" approach would be more fruitful, simply using a long, thin coil?  Essentially, squeeze a coil for a gold detector into a sword-like form, maybe 3/8 x 1 1/2 x 20 in. or so, plus a handle. Can you put the windings that close together? Have a matching steel spike that could be driven into the ground to make the hole for the coil to use. If needed, maybe insert a plastic "scabbard" for the coil.  Even if not very efficient, if it works at all, the coil should be able to detect adjacent flakes down there.

      A Quick Look at The Nokta / Makro Pulse Dive
      I was fortunate enough to field test a prototype of this amazing device and was immediately impressed by the Pulse Dive’s rugged, professional feel.  The solid “heft” of the device made all other pinpointers I’ve tried feel like flimsy toys.  It’s also a great, practical concept—a waterproof diving detector with a deep 5.5” (14 cm.) coil for that converts in a second to a regular pinpointer.  The Pulse Dive features 5 levels of Sensitivity adjustment, selectable vibration, light and tone alert and can be paired with your headphones via a built-in wireless module.   The production model features yellow detail for easy visibility underwater and comes in a sturdy case.  The Pulse Dive kit includes covers for both coils, holster, lanyard, spare gaskets, charge cord and manual.  There's also a second, louder endcap for land use.  This is an extremely well-thought-out device—great not only as a deep, full featured standard pinpointer  but also for quick area searches of  dwellings, stone walls, enclosed spaces--and even as a security wand.   My tests showed the Pulse Dive to have great sensitivity to small gold—even chains.  It also had nice depth for coin hunting on land.  Picture shows a ’32 cent and '38 nickel—my first two finds pinpointed with the Pulse Dive.   A great addition to any serious inland or shoreline treasure hunter’s kit.

      My Profind 35 seems to sound off on nothing and seems to be getting worse. 
      If I turn it on away from anything facing upward it will sound off if I turn it facing down. If I turn it on facing down it seems to be ok but will start sounding off sometimes sideways. I have cut the sensitivity to halfway but that makes no difference. I have a fresh 9v in it.
      Has anyone else run into this?
      (note it is a replacement unit, previous unit the speaker died but would run pretty stable)

      If you've read some of my posts, you know I hate 9V batteries. I finally finished a working prototype of a 9V voltage booster so I can use a rechargeable LiPo in my Pro-Find 35. Here are a few pics:
       

       
      Based on indoor testing, the performance exceeds the stock 9V battery. If you want to learn more, check out my blog post:
      https://gadgetsoftheoutdoors.blogspot.com/2019/05/discussion-getting-rid-of-9v-batteries.html
      I was hoping to use loose AAA cells for this, but it would require permanent modification of the end cap and I'm not ready to do that yet.

      I'm considering the Minelab Pro-Find 15 and 35. It seems like the most important difference on a functional level is that the 15 has fixed sensitivity.

      To any of you Pro-Find users out there, is the adjustable sensitivity on the 35 important? If not, why not?

      Also, is the entire propointer a solid piece of plastic or is there a joint/seem where the black tip meets the yellow housing?
