Pinpointing with Elliptical Concentrics

Can someone please post a video or explain the "PROPER" way to pinpoint with Elliptical coils like the 9x12 and 6.5x9 coils for the ATs???
I am having trouble locking in on targets...I think I have it, but dig a hole to find my targets in the side walls, not the center...
I hate making a mess of my holes...

Thanks,
 
These coils are just fantastic. There are 2 main methods of pinpointing with them. the first method is for coins to a max depth of 4 to 6 inches. Press the pinpoint button, go over the target, then draw it back towards yourself, wiggling a little as you go. The audio will drop of as the target passes under the 12 o'clock position of the receive (inner) coil. It's incredibly accurate and has 2 extra benefits. first, you can feel around a target very well with the toe of the inner coil, to work out it's shape and whether there is one or more targets. The second benefit is listening to the audio fade. The longer it takes a target to have the signal fade away, the bigger the target. Doesn't work if you are only 2 inches away from it.
The second pinpoint method is to use the cut out in the centre of the coil. To do this, press and hold the pinpoint button, go over the target,then once roughly located, come off to the side and release then immediately repress and hold down the pinpoint button. (This is called detuning. The only active part of the coil at this point is the front half of the inner coil.) You now also only have a signal that is 4 inches wide. This will make centering on the target very easy. Once centred, push the coil forward till you lose the signal. At this point slide the coil back till you start to hear the signal again and only move it about a quarter of an inch. At this point, your target Will be smack bang in the middle of the cut out! And will be accurate at any depth. if the coil won't point well at this point after a few attempts, it usually means that you have a large target under the coil and it won't be a coin or ring.
Have fun with it, you'll learn to love it.

Thanks...A little different than the DD coil, but some similarity...I am gonna give it a shot next time out...

HH,
 
[size=large]should be the same from the example for the Ace 250 found on you tube. sounds like what Mick is describing. on you tube you have a video to look at. i find pin pointing with a concentric is much easier than a DD. the de-tuning really zeros you right in.

U gave it a shot, and was much tighter on my targets with these suggestions...

Thanks a bunch,
 
I used to have problems pinppointing when I got my Ace 250 but over the years I got the hang of it.
For me the target is almost always directly under the coil where the rod connects with the coil give or take.
Personally I prefer the concentric coil over elipticals.

I am getting better, but I definitely am wanting to keep the DD on the machine more and more...
