Waiting For Someone Doing A Gm1000 Vs Eq800 For Meteorites

Recommended Posts

Lunk or someone I'm sure will be doing a comparison between the Gold Master 1000 and the Equinox 800 for hunting Meteorites.

Looking forward to that comparison to determine whether I want to add the GM1000 primarily for Meteorite hunting while keeping the 600 and 800 for more general purposes.

I will do that comparison, but I'm afraid it will have to wait until next winter when I'll be back in Arizona.

I did ask Minelab several weeks ago, and the tech support does not have an opinion regarding this.

I am not sure what is wrong with meterorites as targets, and why metal detector manufactures are ignoring these items. It is up to users to purchase detectors and testing them. There is so much mumbo-jumbo and little actual information.

I spent a day and a half last week in Franconia searching the Yucca Dense Collection Area. I used the GM 1000, the Equinox 800 and the GPZ. The heat was intense in the 108 range, and I did cut my trip short.

I have only modest skills and can not give an in depth comparison the way Lunk will next winter but here are my preliminary observations.

All three machines can easily find meteorites. The two small ones I found (2gm and 4gm) were loud and clear. Both were down less than one inch and maybe were on the surface. I boot scraped them before looking.

The GPZ covers the most ground because of its larger coil and handles the hot rocks best, but the weight is a real issue .... especially in the heat. The GPZ is also difficult to get under and around trees, dips and larger rocks. 

I ended up using the Equinox most of the time. I preferred it to the GM 1000. I felt the Equinox handled the hot rocks better and did not false. On the Equinox you can program the one-click user-defined button to switch frequencies to help eliminate hot rocks. 

I also found the Equinox discrimination valuable. Most lead and brass shell cases were correctly identified by the Equinox. The size of the non-ferrous “junk” influenced the target ID numbers but the meteorites strongly registered iron (i.e. negative target ID’s). I used Field 1 and Field 2. I am not yet comfortable enough to ignore the non-ferrous targets, but I might get there. 

A day and a half is not much of a test. More hours are needed. I look forward to hearing how others compare the different detectors.

Fred, I gave the meteorites to my brother but I will get a picture soon.

This is only my opinion....

  My Equinox 800 is not very good with meteorites if you have any kind of discrimination on. With the detector wide open, Franconia is just full of hot rocks and sets the detector off big time, even though it does hit on the detector in wide open mode. But you will be hitting a thousand hot rocks before finding a Franconia.

  I have tested it on both Gold Basin, and Franconia meteorites. Not sure about GM 1000, as I dont own one. The best detector for meteorite detecting is still the 7000, or pulse detector....

Dave, no debate that the GPZ 7000 is the best machine for meteorites. I totally agree as I noted above. The only drawbacks to the GPZ is its weight and lack of a small coil option.

 However, the EQ handles the hot rocks better than the GM. 

The point of my post is that SittingElf should not buy a GM for Meteorite hunting if he already owns an EQ.

As you know (and this is mostly for SittingElf) there are several techniques to successfully work around hot rocks including (1) slightly lifting the coil to reveal the weak signal of hot rocks, (2) changing frequencies to recognize the signature of hot rocks, (3) learning the look of hot rocks in the area you are detecting and (4) a quick kick of the suspected hot rock. On “desert pavement” these techniques seem to work well. They become second nature after a while.

Lunk has had great success with the GM finding meteorites. He may have additional input on the techniques he uses.

      First two pics are from previous hunts at a fresh water beach with the ID Edge.
      Found an area where the sand moved out a bit and made some older finds.  The 2 large rings had been in the water quite a while the small one is a newer drop probably from last year all marked 925.

      and today's very first finds with the Nox.  Small Sterling Silver bracelet and the usual stuff.  The melted car looks a bit like a Delorean that perhaps did too many time travels and the large metal ball.. I have no idea what that's from. Perhaps a weight from a fishing net?

      Well for me at least 😀 So another 2 hour hunt at the pounded out early 1700's Hole, abandoned prob around 1850 or 1860. I Kept circling in the general vicinity of the home site and found a few more buttons and lead bullets. I had a faint but audible signal which read 13/14 and from a good depth out came the little Georgian strap buckle. The buttons were reading at 9/10 in Field 2. The little buckle might not be a silver coin but I'm totally happy that I found it. I've never found one so small or seen one to be honest! I think the conical button might be militia issue as I've had them before with militia insignia on the front. I like that button because the shank is Wayyy off centre! I guess that one was made on a Friday 😁 I thought I might be out this weekend but its rain/thunderstorms both friggin days 😢 Good Luck to all who get out! I'm really starting to think this Nox 800 is going to be one heck of a ride!
      Oh, penny in there for scale.

      I got my new equinox 600 in and noticed the armrest strap is too short to make it back to the velcro.   Basically it hits the velcro but only maybe a 1/2 inch.  Anyone else with this issue and what did you do?

      Had a great club hunt last Saturday - found some type of ID tag.  Been researching all week but nothing yet... This was close to a foot deep ..

      Even though the Equinox handles the old school yards where they have discarded the coal waste for decades, it still struggles when the ground is saturated.  I went hunting Sunday and the machine was very hard to hunt with, continuous ground chatter.  Tried each preset program with both GB 0, manual GB and tracking and all displayed issues with this ground. Finally, I opened up the screen and the results were astonishing, continuous iron audio reports from the waste.  Decreased sensitivity to 15 and increased the recovery to 8 and finally started finding non-ferrous items mixed in the cinder waste.  Amazing just how fast this machine can recover amongst all the cinder.  The ground really needs to be bone dry to hunt with a VLF machine of any kind but the Equinox did okay.  My PI machine is still the raining champ when it comes to this type of ground conditions.
      Still waiting on 1st Texas and their new PI and I’m hoping it has some sort of discrimination feature.

      I had about 90 minutes around lunchtime on Sunday, while my wife and son were out shopping, to hit a couple of the vacant military family housing units within walking distance of our house.  THese houses are scheduled for demolition this year, and were built between 1958-1964. Two small front yards on Park 1, NC, GB Auto, 20 sens, APTX LL phones, Ferrous 1, 50 tones, 3 recovery.  
      I actually ignored what were likely pennies after the first half hour. Looking for better.
      Ended up after 90 minutes with one Silver 1951 Quarter, 2 wheaties, four clad quarters, six clad dimes, one nickel, and six copper pennies.  The unusual was a 1940's-1950's US Air Force button, and a Fleur de Lise (sp?) Large button from the front yards.  Happy to have hit silver again within 3 minutes walk from our house, and a military bottle opener as a final bonus!  Lovin this 600, and can't wait for the 800 I still have on order!  10 days to go before we move from this base in Florida to Oklahoma. Hopefully, virgin ground on base there as well!
