Popular Post Steve Herschbach Posted December 9, 2024 Popular Post Share Posted December 9, 2024 As a person who detects in highly mineralized ground I have found air testing of almost any sort to be questionable at best in determining real world performance. The results seen absent the ground can be 100% opposite of the results seen in the field. What separates the great detectors from the rest is the ground handling capability. These tests absent ground are removing what is perhaps the most important aspect of metal detecting, which is detecting targets buried in the ground. I'm not saying you can't learn anything from air tests, mainly setting baselines for max performance and learning target id numbers, tones, etc. But again, I have seen results from air tests reverse entirely in actual real world use and so in my opinion these types of tests can be very misleading. It's like EPA mileage estimates versus real world fuel economy. The two things can be entirely different. If you are so lucky as to detect in very low to no mineral ground you can place more trust in this type of testing. The higher and more extreme the ground mineralization the less accurate you can expect these tests to be. 11 Link to comment https://www.detectorprospector.com/topic/27106-3d-unmasking-test-cube/page/2/#findComment-285952 Share on other sites More sharing options...

EL NINO77 Posted December 9, 2024 Share Posted December 9, 2024 Nexus 3D test ...can be for example ... an example for standardizing 3D testing... which is not a bad idea... because it allows you to change the position of iron as well as coins precisely... I always nod positively to some step with a measure towards standardizing such testing... such testing will give you a basic idea of what the tested detector can do.. As Steve says ... finally the testing needs to be confirmed in the field... because difficult terrain can weaken the signal of the coin and strengthen the signal of iron... or in some cases even give deeper buried iron as a non-ferrous target...... I also have my own test field.. a really old field that is laid out with stones on which there is a lot of iron and among it a few masked good targets..../.. which are not plowed,, and which only I detect...,, where it is really difficult to find a good non-ferrous signal.. and where such a signal can mean a really good target. For me, one of the ideal terrains for testing.. because I have full control over this terrain,,and also because I've gone through it with several top detectors for a total of about 200 hours.....Atrex several coils, XP ORX 9"hf coil, Equinox800 11" and 6" coil, and finally I detect the terrain from VERSA.. I was in the field 2 days ago... to check the capabilities of the detector I'm using /and new 24DD coil/... and I recorded videos from the testing... -------------------------------------------------------------------------------- Iron in the field around dig up coins..old up to 2000 years old forged large and small iron..is very unpleasant in this field...it often gives a good non-ferrous signal...so another art is to identify and choose the really right signals.. 2 Link to comment https://www.detectorprospector.com/topic/27106-3d-unmasking-test-cube/page/2/#findComment-285964 Share on other sites More sharing options...

After watching your videos. I’m asking Santa for the new 24DD coil for Xmas, as I really like the sharpness of the sound from it! Thanks for sharing those videos with us. 2 Link to comment https://www.detectorprospector.com/topic/27106-3d-unmasking-test-cube/page/2/#findComment-285971 Share on other sites More sharing options...
JCR Posted December 10, 2024 Share Posted December 10, 2024 Many of my Red Dirt relic sites are similar. The ground is unplowed and the Iron is old & has a solid connection with the ground. The small iron is very falsey and it is difficult to discern good signals. Even high Iron Filter settings do not really help tame the falses. You just go slow & listen carefully for that little extra something in the sound. Everything left is small & not a high conductor. Once the iron is dug up it does not false. Very challenging. 2 Link to comment https://www.detectorprospector.com/topic/27106-3d-unmasking-test-cube/page/2/#findComment-286021 Share on other sites More sharing options...
Johnnysalami1957 Posted December 10, 2024 Share Posted December 10, 2024 I just want to find stuff not become an astronaut But have at it fellows.

Never really heard of the 3D stuff as it seems to be a relatively new problem. I thought all targets were in 3D. Unless we only look at surface targets.

EL NINO77 Posted December 11, 2024 Share Posted December 11, 2024 I recommend everyone ..to find time and do a few 3D tests... because it's not just about the test result itself...it also shows you the complexity of such separation...but mainly this 3D test shows you how to work with the coil for such detection. In this test .. where there are 2 2.5" nails on the surface and a small 15mm coin at a depth of 7cm ... you will see what the possibilities of the given detector and coil are.. 3 Link to comment https://www.detectorprospector.com/topic/27106-3d-unmasking-test-cube/page/2/#findComment-286075 Share on other sites More sharing options...
