Testing the Fisher F-2 in DIRT VIDEO

Hey Badger. I was just wondering if the test is set up properly. (just brain storming not criticizing) The way you have it set up the coil is going from air to ground to air. Could this confuse the detector? I herd some place the coil needs to be in close contact with the ground once it is set up. Some one jump in and explain it better or tell me it doesn't matter.

The problem here is if you touch the ground with the F-2 coil you get a false signal. See in the video where I show that.

With many detectors bumping the ground is fine due to coil construction. Some detectors require a small distance between the coil and the ground or grass. This is one of them.

Badger

Badger I am lousy at explaining myself. Your coil when not over the bucket is 3 ft from the ground, then moving over the target it becomes 1 inch. Then when passing the target it becomes 3 feet from the ground again. Would that have any effect on the machine? Probably a stupid question.
Burdie

It's not a stupid question. I usually ask those.

No, the drop to the ground wouldn't affect anything because this is a factory preset machine in ground balance and it's a manual set machine in sensitivity.

The drop may have some affect on detectors with automatic ground tracking and auto sensitivity.
 

Badger,
Would it be possible for you to place the quarter 6 inches deep in a larger diameter bucket?
[Maybe like that 5 gallon bucket shown in the video.] [Maybe take a knife and cut the bucket down to 6 inches high]
And then repeat the test? I can't help but think that the small bucket is affecting the results.
I would like to see the F2 do better so I could buy one. TIA---Merf

I was going to do that Merf but I already know what the results will be so that's why I didn't do it. At this point I'd rather dream that a larger container would mean more depth. If I do the test I'll distroy the dream.

I've done a lot of this in the past and the results don't surprise me at all. I've tried to be very gracious in what I said on the videos. But the bottom line is this Merf, our VLF detectors don't really go as deep as we'd all like to think they do.

There are some old timers on here who have known this for years but they generally don't wish to make trouble and ruin the fun for others. You and me have discussed this before and we both know exaggeration rules in this hobby.

The VLF machines we have today are better than the old BFO and most TR machines of the past but they're better by a much smaller margin than any of us want to hear (including me).

PI or something else (not VLF) will one day totally revolutionize this hobby. Today we are missing more than we could even imagine. In the future a new group will hit our old worked out sites and wonder if they got there first.

I've chatted with some who now use the Garrett Infinium and these people go to beaches and Civil War sites everybody has given up on and they dig plenty of goodies (plus buckets of trash). One of the most important members of TN told me his Infinium finds dimes at 14 inches deep at the beach. I've got a new Infinium on order now and it should be in next week.

Hey Badger, Thanks for the video, did you try to turn the sensitivity down on the F2 to stop it from falsing when the coil touches the ground? I believe the sens is important on a machine that has no manual GB.
I have read posts from guys who hunt in saltwater with the Fisher1280x and turn the sens down to 5 to knock out the falsing and claim they do not lose depth. I am lucky, by me I can run almost up to 8 on the sens in the salt with my 1280x.
I have also read some ace 250 posts and many of them are running at 50% sens.
Thanks

The main purpose of this test was to see how deep the machine can go in fresh dug soil. To determine this we need maximum sensitivity on these low end detectors. The sensitivity knob is the depth knob on these.

Sorry I didn't further explain why I made the suggestion on turning down the sens, I just think there may be a problem with the machine. Is it really supposed to false like that if you bump the ground?. I swing pretty well but do bump the ground, that falsing all the time would result in being able to see the machine fly thru the air over a long distance. ;D
