Double-Blind Testing

Has anyone done this test?

Scientists perform double-blind testing on a regular basis.
LRL manufacturers never do this, as it would reveal an uncomfortable truth.

I do something similar to the db test. Actually I consider it a more accurate test. I close my eyes, cover my ears, spin around a few times, toss the test target, spin around a few more times, then do a search. Of course if I visually spot the target, the test is voided. Instead of ten possible locations, my 20 x 40 feet test area has many more possible hiding spots even if I consider anything within 18 inches as a good hit. That is approximately one square yard.

My critique of Carl's db test is it requires so many repetitions the person is very likely to get confused/fatigued. That is the skeptic strategy. Also the ten distinct "hiding places" makes it more of a guessing game, what is known as a "forced choice". Although an experienced user can probably work around this, it is not the natural way of locating a target.

Most importantly the real test should be able to prove the device can actually physically discriminate. The target type (gold, silver, etc.) settings on the device should not be known by the user. In other words, the device should be set and then covered so the user does not know what type of target they are searching for.

With your lrl-confidence, you are ideal target-medium for this:

It seems to me simple test and I will can do it but the process sounds complicated.

I will find a process to match on site in the test area.

I will make video and I upload it to youtube.

Don't lose your time.
Here, nobody sceptic will believe you..... except if you will make the test near to their armchair....

Geo said it correctly. There is a gaggle of vultures circling overhead just waiting to swoop down and pick your bones clean. The skeptics will never accept a video as proof, nor should they. Like I said the only test that really should matter is the one where the user does not know what element the device is set to search. Even a baited coat hanger (with a qualified user) should be able to pass that test.
