Some Thoughts On Coil Swing Speed Which Will Improve Your Hunting Skills.....:confused:

[John-Edmonton]

Just as running a magnet over a coil of wire can produce a voltage, increasing the speed of movement will also increase the voltage, or again, an alternator will give out more voltage with increased revolution speed. You can use these same principles to dramatically increase your hunting skills.

Increasing your sweep speed of the coil over a target will in fact give a stronger reading, and is one way of getting a stronger signal from a deeper target. I use this to my advantage when using the sniper coil. Because it is already a very sensitive coil, especially to smaller targets, I tend to really swing it fast, as much as 2 swings a second. This allows me more coverage in a given time and at the same time gain better sensitivity to deeper targets. Now there are limits to as how fast the electronics can digest this information. Older detectors from the 80's & 90's didn't fair as well on scanning the coil over several targets set up close together, to get some reasonable ID. Today, the coils and electronics allow the user a much faster swing speed.

So....learn your detector well. Establish your maximum swing speed using different size coils and their swing speed capabilities. This can be done by placing targets spaced about 4-5" and swinging your coil back and forth, increasing the speed to where the electronics can't ID the targets properly. The downside of a very fast swing is that the user can get sloppy and miss some areas and possibly damage the coil by physically hitting a rock or tree.

Just something to think about......

Gee, John. I just saw your picture there. Have you had some work done? thanks for the tip. Never thought about it that way and it was not what I expected to find when I saw your subject line. It's good to know because on occasion I've given myself a tounge lashing for swinging too fast....now I suppose I owe myself an apology.

I think the key is to learn whatever detector you use, and find the best swing speed for the size/type of coil your are using and the type of target you are searching for. I don't whip that coil as fast for deep targets, as I get sloppy, but when I do get a signal, then I sort of play with it with an increased speed. Searching schools and parks for coins and rings allows me to swing quite fast.

I agree, MrGee-John's looking so much better! I found this out by reading Bill's comments when he was here and partly by myself. One day I swung the sniper like a golf club-as fast as I could- and the target got louder! By experimenting, I found I could speed the coil at 3 bars sensitivity and have almost the same depth at a regular speed 4 bars. Finally, when I found a target at 4 bars, I could then slow the coil down and if the sound stayed, it was usually a coin but if it disappeared it was usually a large iron target that was deep. By speeding up or slowing the sweep speed, you can obtain a lot of info. Nice post, John.

thanks for the information.will give it a try

Swinging fast ALL the time is NOT benificial...the detector has a very fast recovery speed, but still needs time to think...I use that fast wiggle over iffy signals and those whisper signals...It sometimes pulls em out a little better...

This is a very dangerous post because you say "will give a stronger reading". If you said that with some detectors due to either their filtering, or on some ground, or with certain coil designs and sizes this applies, fine. But general statements should never be made.

I think the theme here is experimenting.

Yes, I was referring to the AT Gold. There is a quick reset speed so that even at moderate speed a deep target might get passed over. Now some people obviously have a different idea of what "fast" sweep speed is. I hear some people talk about a four second sweep with those multi-frequency detectors. For them, a two second sweep is considered fast. My testing showed that if you swing the coil six or seven inches to each side of the target you have to work to get enough speed for the deep ones. Of course you don't want to go crazy and damage your machine and it's a lot easier to get speed if you make a wider sweep. Like I said, watch those videos at the Garrett website, like the ones in the trashy park. Those guys swing fast. When you swing fast you skip over some of the surface stuff. That may not be what you want. But if you are not finding deep targets it's worth your while to try a faster sweep speed.

People skim read and the first statement they hit is that sweeping faster "will" give a stronger signal. I rarely come on the Finds forums but had three e-mails and two phone calls about this in one day.
