DETECTOR TESTS A Question I am asked on a daily basis is ''How deep does it go''? - '' What's it like near iron?'' I can only guess the answer to this question. I know roughly if one detector is better than another but that's about it. Most detectors fit in to the ''mid range area'' where they are all very similar.
This is a very rough guide , I do not spend hours turning knobs and pressing buttons, nor do I take in out for day in the field. All detectors are set up to be stable and reject nails and small iron, which is what suits most people. I get e-mails on a daily basis saying '' you will get another 2 '' if your run it in all metal '' or similar Quite a few detectors would give better results if I ran them ''over sensitive'' or in ' All metal'' making them very unstable but I would not normally do this in the field.
The conditions reproduced are average - all the big iron has been taken out of the ground and small nails left in - The ground is disturbed but compact; similar to detecting on stubble. Most detectors will go a bit deeper if the ground has been undisturbed for 100's or 1000's of years. But of course these conditions cannot be reproduced. I had a few shocks while doing the tests but mostly it was as I expected. As most of you know, -you rarely get two detectors that are the same make and model to perform the same. You get good or bad whatever you choose. Most of you will never know because you have nothing to compare it to. Some of the detectors below may have been good examples or bad. Some makes of detector work better on some fields than on others, whilst some makes of detector work anywhere without picking and choosing. Some detectors may not be very deep but are very fast responding so they would be better in iron infested sites. But I have found if you have a detector that is not the fastest at responding you just simply slow down. Depth is not the 'be all and end all' - but it helps, the more powerful the detector the more it normally finds. I will add to the list on a weekly/Daily basis.
