The places i hunt are very iron infested. I currently own 9 detectors 4 of them are top of the line from their respected companies. All nine will pass the nail board test. I am about to list and sell all 4 top of the line machines because they cannot pick up a silver quarter 2.5 inches deeper than two rusty nails that are placed at each side of the quarter facing away from each other. The nails being 1.5 inches under the top soil themselves. I have 3 machines that will, and one that barely does pass, all of them interestingly are mid price machines.
Almost any detector made will pick up a non ferrous target as long as it is above the nails , no matter what fashion the nails are laying under the target.
Quite a few will pass the nail board test or any other test as long as the nails are in the same plane as the target.
Where machines start to fail horribly is when the good target is deeper than the nails themselves, which we all know is a very real concept and a real life situation.
I have found there is a difference between air tests and in ground tests trying to resolve which machines will pick up the good target below the nails. Unfortunately i do not have an undisturbed soil condition test bed situation to test as it would take years to make this a reality. I stated this because i know i will hear how minelab machines do not do well in disturbed soils.
With 3 mid priced machines that are very good at this scenario i do not want to spend any more money at this time buying another top of the line machine only to be disappointed in the end.
So i am asking if any of you testers that received a test machine if you could maybe video a similar scenario and post your findings? Would help me immensely do decide if the impact might be a consideration for me.
Thanks in advance if you decide to do this.
