interesting results, the ace 250 surprised me. I guess i need to find some gold soon and try that test myself.....

 

[Charlie P. (NY)]

In the last video he's not giving much of a swing arc for the test. Wonder why he opted to test that one without a shaft?

 

[LuckyLarry]

On the last one he's trying to show just how fast the Omega responds/recovers past a piece of iron. It is the only one of them that can even get close to keeping up with the old Compass - for recovery speed. That's because the Compass has "vari-filter', and the other ones don't. Compass still has patent rights.

 

[mrwilburino]

Yes, the Compass certainly made it look easy. So what's the status of that technology now? Tied up in red tape? Or maybe someone has a plan for it?

 

[LuckyLarry]

Steve is making a few custom detectors now, but mostly he repairs or modifies them. He is still operating in Forest Grove, Oregon. You can get his ph number off the Compass forum on another site. The guy at East Texas still repairs and modifies them too. His name is Keith Wills. Keith had a lot to do with the increase in depth of detectors made since those days, and he worked for Compass too.

It's rather strange sometimes to realize that much of the old technology beats some of the new stuff. To this day I have never seen a deeper all-metal mode than on the old Fisher 400 series or the original Garrett Deepseekers from the 70's. Even in the toughest of ground they still blow the doors off of some of the 1000-$2000 "state-of-the-art" detectors made today.

That type of technology is still being used by Garrett and Nautilus, but people want mostly toys, bells, and whistles now, not raw power.

I always knew that my Sovereign would not pick up a coin by a nail............... But the Minelab cult will say that the video is not right........ You know the detector is not set up right ... Or it is trick ect,ect........

The omega sounds like classic cz all metal autotune, no sharp beep beep. Very interesting videos. Very interesting indeed.

Well the cz & omega are built by the same people........ could be a connection there..

I just dont get the omega video. The machine is set in all-metal autotune. It will sound like that over just the nails

Don't know much about setting up an E-Trac but that coil is big, no wonder it bombed. The one thing I noticed was the machines with smaller coils did best.

Like i said the Minelab cult will find all kind of reasons the minelab failed.....They can't face the truth.....Looked like the AT Pro and the G2 had on big coils.........

 

[dirtscratcher]

Another thing my explorer sucks at is finding coins in the air. What do you use to collect them a butterflynet.

I'm not part of the Minelab cult, as a matter of fact I don't own any of the detectors tested. The AT Pro and G2 had longer, narrower coils that do a better job at target separation. Those two coils are kinda of a trade off, their trying to achieve depth that a larger coil provides yet maintain target separation of a smaller coil, they also work better in mineralized soil. I've noticed that seems to be the current trend among the newer models hitting the market these past few years. The coil on the Minelab is just big, and is made for depth in mineralized ground, not target separation. It would be interesting to see how the AT Pro, G2 and the Minelab would do with smaller coils with the same test.

I did not know that was a air test... I thought it was a nail board test.... and a speed recovery test..... Sort of like the one Norfolk Wolf does....................... AND ANY HOW the way we all on this forum hunt coins is in the air ....... And recover them is with butterfly nets............... DIRTCATCHER i know you have not caught up with the times yet.... You are still looking for coins in the ground and useing a spade to dig them up with.... Darn man are you behind the times.............

 

[dirtscratcher]

What I should have said is. I find coins with rusty nails in the same hole. I find coins in the ground deeper than air test. I find nickles lots of them, and the occasional gold ring. All things I keep reading the Explorer or Etracs won't do.

 

[pennyfarmer]

I also find plenty of coins next to iron with my minelabs. In fact my first silver dollar was found on a dirt pile nearly underneath a large piece of sheet metal.

I don't know anyone who swings a minelab as fast as is in the video. I am not criticizing the person who made the video only saying that sweep speed is critical when hunting with any minelab.

 

[U.K. Brian]

If it was like Norfolk Wolf's nail board tests then don't even bother watching.

Coil sizes and types should be matched as far as possible. Sweep speed should be what the filtering requires. So could be very slow or rather fast if it was a four filter like the Spectrums/XLT's. Then the recovery speed should be adjusted as well. No reason why on screen you should not see the discrimination being set to just cut out a standardised sized nail, not one detector set at twice the level it would be used at in real detecting.

Re the Compass "Vari-filter" system when I asked years ago I was told it didn't vary. It was just three filter rather than the standard 2 or 4 of the time.

 

[LuckyLarry]

Brian that's a yes, and a no. The detector chooses whether to use 1, 2, or 3 filters, depending on what the sampling determines.

A question was asked about AT Pro's and small coil so I'll toss this in the mix and you make your own determinations folks, rather than pointing out the obvious for you. I know this isn't exactly the subject at hand but it is useful info:

Here again is the AT Pro: www.youtube.com/watch?v=-WS1TBWulxg

There are two other videos online that show a slight edge for the nail board test for the G2/BG Pro and their sniper coils, with the AT Pro looking, well, maybe not (quite) as pretty? I didn't save those videos because I'm not really keen on the performance of the AT Pro overall: As you all well know though, coil size plays a noticeably more minor role with the newer coils now being made. But the Compass even when using an 8" blows some of the newer stuff right out the door, even when they use a smaller coil, or so it seems when doing the tests personally.

A final note: I have a tiny 3 1/2" coil for my Compass Relic & Coin (AKA GoldScanner Pro), and it matches the Omega and G2 sniper coils for depth, and often it separates better than either. It really astonishes me sometimes as to how deep it goes for such a little coil, especially at 9-10" on a clad dime. Sorry, no vid for it. Maybe later on.

 

[U.K. Brian]

Just dug through years of notes to find the following info. from John Earle who I think designed all the Scanner series for Compass.

"The Vari-filter series has added propriety electronic processing over other "2" filter designs to eliminate the ringing that results from a higher Q filter so that you end up with better ground handling than most two filter types yet it reduces the "ringtime" associated with 4 filter machines". (Ringtime being signal trailing that can make two targets sound as one).

So your correct. Nice to see some considered tests rather than those aimed at making some detectors appear worse than they in fact are if given an equal playing field.
