Here's Another Trick For Both "AT" Detectors To Get Even Better Depth :detecting: :detecting:

[John-Edmonton]

First of all, when hunting, find any fairly deep target. Or bury a small piece of tinfoil say 1/2" x 1/2" a couple of inches in the ground. Make sure you are not discriminating it out. Now swing your coil over the target, your usual speed and start raising the coil until the sound stops. Now........speed up the swing speed, and notice how much louder and higher the target reads. Now repeat this scenario, at even faster speeds. You will find that eventually the faster speeds will start to make the target sound shallow again with less audio. Keep experimenting until you find the speed which gives you the most depth. Try and remember this speed or rhythm. It will give you extra depth in areas where you may want it. You don't need to use this fast swing speed at all times, as it will wear you out, and if there are no known targets DEEP in the ground, it is not necessary.

From many hours experience, this technique works very well using a smaller coil like the 4 1/2 inch sniper coil or the 5" x 8" new DD coil for the AT Series, which I hope will eventually be made available for other existing Garrett lines. Swinging a smaller coil gives you better accuracy in tight areas, especially in the woods so you don't whack it against trees or rocks, while at the same time not tiring you out due to it's less weight. And.....you end up covering a lot more ground in a given time, while getting better depth and sensitivity.

Works for me!

Good luck and I hope your good finds increase even more.

J-E, which coil weighs less; the 5x8 or the 4 1/2?

 

[John-Edmonton]

I am pretty sure the 4 1/2" sniper coils weighs less.

Excellent tip, John. Thank you!

It is strange that this subject has come up at all. I have discovered this too, and one can swing the ATP so fast that it will miss shallow targets completely. There is a section of the manual that illustrates 1m/sec as the swing rate, "Scan side to side approx. 3ft per second." Another interesting thing I found with an "Air Test" is that dimes, pennies, nickels, and quarters are detected at greater distance if the coin is moved from the back to the front of the DD coil. Side to side shows less depth. Has anyone else seen this?

No way John... at least in my ground... faster swing and beleive me I swing fast to a point. get a Hi tone on minerals-rusty pockets,,, also swinging fast get a hightone on a zink type target...
and I do explore almost all beeps.
but I cannot beleive what you posted.

 

[MrPopTop]

Also I believe u recover targets to 3 inches or so...
You are blessed with a nice location as well..
Also the AT Gold will do just as well as the AT Pro for you doing what you do...
For the park hunters....the hunted out parks... AT Pro is the machine

 

[MrPopTop]

When is the last time you dug down 8 inches?

 

[MrPopTop]

I fully think a savy user could do as well as you in the parks or snow banks with a bounty hunter tracker 4
This is no personal attack...........
Just saying

I am not sure if I have missed the point of these posts or not.
It is perfectly normal for any VLF metal detector to have an optimum sweep speed that faster or slower than will cause all targets to produse a weaker signal. and to not respond to weak signal targets at all.
That is why some of Garretts detectors have Sweep speed correcting ccts that enable the detector to be swept at almost any speed and still produse a good response to all targets.

Did I miss the point?

You are correct, but some people are not aware of the sweep speed issue, and want to use anything they can to their advantage for increased depth and sensitivity. Along with a new series of metal detectors being released, come a lot of new users. I want to give the new users some tricks so they too have an opportunity to get great finds like the experienced guys.

So if you get those results, why are you complaining? You have just figured out a way to ID zinc pennies. If you charted the ratio of swing speed on a graph, the results would probably be similar to a standard bell curve. Too slow speed is poor, speeding up the swing speed gets improvements until the swing speed goes too fast, where the improvements start to decrease. As I suggested, find the spot for maximum performance. Use it to your advantage.
