Video - Understanding Iron Masking And Target ID


Recommended Posts

This is a video that Garrett has done in response to some of the user videos made about the new Apex. It’s possible this was posted before and I missed it... been busy lately!

“Iron targets can “mask” or change the Target ID of adjacent good treasure targets. Two examples of target masking are presented, along with a demonstration of successfully scanning coins mixed into a row of nails. Although the presence of iron can change a target’s ID, this video shows how easy the Garrett Apex can pick out the treasures in such trashy detecting environments.”

I've conversed with Monte a few times about these videos that Garrett released and why Garrett seems to do so much better than what I got or even he got. I think I already posted (I can't remember) about my nail board being smaller than the official Monte Nail Board so Monte sent me one. Sure enough the Apex does do better on his official sized board I can get 6 out of 8 rather than 4 out of 8. But on the flip side the Simplex and the F19 do even better. The other thing that makes the Apex perform better in iron is coil height above the ground. We found that if you hold the coil approximately 3.5-4 inches about the nail board or the line of nails and coins the Apex does much better. Now in the real world I don't go around swinging my coil that far off the ground, 2 inches at most. But at least the info is there if you happened to need better performance. Obviously that's only going to work for surface targets.

All well and good in a test garden. Real life, where the targets are a different depths and orientations are another matter. Add various degrees of corrosion and non-ferrous trash, and that I.D. averaging is going to be a problem.....not unlike some other machines. The quick processor will help however, as would a small coil.

  Test gardens are what they are, like air tests! I'm sure Garrett has some substantial test gardens!

    Steve does do decent videos, compared to some of the goofy one's out there! I do hope that they process all the feedback for the Apex rapidly, and get the AT design progressing! And hopefully updateable!👍👍

Great Video Steve,  thanks for sharing!  I never really thought about iron mixed with good targets "Averaging" or lowering the VDI.

Yep, this is a fairly common problem.  In some detectors such as the XP Deus, adding some discrimination, while still allowing the iron to be heard via iron volume helps to mitigate this phenomenon versus running with zero disc.

      So having used and test the Garrett Ace Apex for a bit now. I've come up with some things I do and don't like about the machine. If anyone is on the fence about buying one this might help you make up your mind.
      I think Garrett is heading in the right direction with all the modern features they have included on the Apex. Here's what I really like about the Garrett Ace Apex.
      1.    Wireless headphones
      2.    Backlight display
      3.    Rechargeable battery
      4.    Easy to navigate menu
      5.    Easy to read display
      6.    Great sleek look
      7.    Light weight
      8.    Ground balance capabilities
      9.    Weatherproof design
      10. Adjustable frequencies
      What I don’t like and why, yea I know you can’t have everything you want with a $425 machine.
      1.    Lack of accessory coils-IMO the 6” x 11” Viper coil is too big for trashy sites and not big enough for clean sites.
      2.    Iron audio-IMO the iron audio on the Apex is pretty much worthless. It’s too loud even on 1 and the machine can’t reset fast enough and drowns out good signals close to iron when iron audio is used.
      3.    Notch discrimination-notching out 5 segments at a time is too many. With the Apex already struggling at depth and in iron, you need to be able to notch out one number at a time so you don’t lose targets in iron or make them even more jumpy when the target is deep.
      4.    Lack of adjustable tones-5 tones on this machine doesn’t work well, especially in iron trash. The iron tone and the very low conductor tones are too close in sound. Yea you can hear the difference but since this machine pulls down target ID so bad in iron, a 2 tone option or even a 3 tone would be much better so there is a distinct separation of the audio.
      5.    Lack of usable search modes-Really all you get with the Apex is set discrimination patterns, not search modes. When you change modes you simply notch out different segments you may not want to dig. Depth and separation remain the same, many other machines on the market both more and less expensive change the recovery and depth in relation to the mode you choose.
      For those of you that have the Apex or even if you don't, I would be interested in what your thoughts are on the Apex.
