Rob, the Pro Sonic already has 3 watts of amplification built into it; adding the screamer on top of it would be overkill. But it would be interesting to hear what it sounds like...if the external speaker survives?

Sounds like a new innovation never seen in a single-frequency VLF detector before; knowing Minelab, that wouldn't be a big suprise.

From the specs it appears to have basic iron reject capability denoted on screen as a chance for gold as Steve pointed out, along with a deeper, all metal mode without any discrimination.

Right on Dave, I was hoping that others would chime in with their Zed space rock finds; thanks for sharing. The pulse induction machines are notorious for being unresponsive to certain types of meteorites that a VLF can see, but like you said, the Zed sure nails them!

The Minelab GPZ 7000 is an excellent meteorite detector. At the Franconia strewn field, the three small fragments shown below were "bread crumbs" that led me upslope to their larger parent individual; all were buried beneath the surface.

When browsing the specs link from page 2 of this thread, I noticed something new that I've not seen in a detector before: 2 automatic sensitivity settings, Auto and Auto+. Any theories on how these work? Perhaps they work in tandem with the auto ground balance and maybe Auto+ is some sort of sensitivity boost?

With it's extra sensitive VLF performance, Minelab's new Gold Monster should make a superb meteorite detector: http://www.detectorprospector.com/forum/topic/3013-new-minelab-gold-monster-1000/

Looks like the new GMk will be a great lightweight patch hunter.

...and more tasty!

Same here, Steve. In fact, before I educated myself about meteorites, I thought they were only iron.

Here are a couple that my mom found a few years ago: a 166 gram iron near Quartzsite, AZ and a 161 gram Franconia individual stone.

What a tremendous find!

Very interesting and informative articles, Steve, thanks

Logically, if your specimen is in fact a meteorite with very little or no nickel, it would only be very weakly attracted to a magnet. The fact that it is strongly attracted to a magnet, gives a null response on your detector and has no discernible fusion crust or regmaglypts (thumbprints) points to a terrestrial origin - magnetite. Also, only freshly fallen meteorites are black, and they have a smooth, uniform surface, never broken up and pitted as the surface of your specimen shows. Example of a freshly fallen stony meteorite:

Here are a few more of the meteorites I've found within the Franconia strewn field. This is a "puzzle" meteorite; several fragments that fit together. They were all excavated from the same dig hole: This beautiful individual stone was hidden in plain sight among some basalt boulders: This nifty little chondrite was also nestled between basalt boulders: This small individual was found while revisiting an area in the small end of the strewn field, an area that a friend and I first detected for gold nuggets in 1999. We didn't find any gold, but each of us did find a handful of small "hot rocks" that we tossed aside. Had we known then what stony meteorites were, we may have been the first to discover the strewn field:

A few years ago I was detecting in the Franconia strewn field in Mohave County, Arizona. Out of the corner of my eye, I spotted a reddish orange rock that stood out in stark contrast from the surrounding light-colored soil. After careful excavation, I was holding the largest meteorite I've found to date.

The desert trumpet plant thrives in mineralized soils and is present in the goldfields that I frequent throughout Nevada and Arizona: https://www.google.com/amp/nuggeteer.com/gold-prospecting-and-metal-detecting-adventures/desert-trumpet-plant-eriogonum-inflatum/amp/?client=safari

Wow. That's a huge space rock, Dave - congrats! Those others wouldn't happen to be Nininger meteorites in your photo, would they?

Great find, Fred! Those fine flow features are fantastic...looks like it was oriented. Thanks for sharing.

Another cold find from northern Nevada. I was detecting for gold nuggets with my GPX 5000 along a narrow wash that had lots of exposed bedrock. Upon hearing a moderate signal, I looked down and instantly recognized the small meteorite; you'll notice in the pic how it stands out from the surrounding soil and rocks. I'll never have this one classified because it's a complete individual; cutting it would ruin it.

There's not a lot of activity on the meteorite forum, so I thought I'd start a new thread to hopefully jump-start things. It's an invitation for forum members to post pics and/or stories of theirs or others meteorite finds. When I'm not hunting gold, I'm chasing meteorites. There's nothing quite like finding a rock that is literally out of this world. For meteorites that I have had classified, I've included links to their entries in the Meteoritical Society's catalog of officially recognized meteorites. They are cold finds; for those not familiar with the terminology, a cold find is newly discovered meteorite that is not part of any known fall or strewn field. So enjoy, and lets see some meteorites! https://www.lpi.usra.edu/meteor/metbull.php?sea=Diablo+Pass&sfor=names&ants=&falls=&valids=&stype=contains&lrec=50&map=ge&browse=&country=All&srt=name&categ=All&mblist=All&rect=&phot=&snew=0&pnt=Normal table&code=35516 https://www.lpi.usra.edu/meteor/metbull.php?sea=Quartzsite&sfor=names&ants=&falls=&valids=&stype=contains&lrec=50&map=ge&browse=&country=All&srt=name&categ=All&mblist=All&rect=&phot=&snew=0&pnt=Normal table&code=35634 https://www.lpi.usra.edu/meteor/metbull.php?sea=Imlay&sfor=names&ants=&falls=&valids=&stype=contains&lrec=50&map=ge&browse=&country=All&srt=name&categ=All&mblist=All&rect=&phot=&snew=0&pnt=Normal table&code=52855 I'll have more to share later...

Nice!

Thy coffers overfloweth! GOY

Brian, A quote from JP in another topic regarding the GPZ seems to be applicable here: "Difficult and Normal: Difficult removes ground signal but also the null points of the modes (High Yield, General and Xtra Deep) are different to each other across the Ground Type modes (Difficult compared to Normal). For instance a 1/2 ounce solid nugget will give a better response in General Difficult than in General Normal, this is not due to ground signal but more to do with the modes sensitivity points. Some nuggets will fall into a modes least sensitive position that's why it pays to go over ground with a variety of modes."

Awesome Steve - sounds like a new project for you to work on! Just wondering if you can stuff it all into a light-weight housing...you'll have a winner. ?
