Ace250 standard coil.....

[robert roy]

The standard coil for the ace250 is eliptical. I have a hard time pinpointing with this coil. The little 4.5 sniper is always dead on. I have to wonder if there is another Garrett coil such as an 8.5 that would work. It seems to me a concentric is eaiser to pinpoint with. Any suggestions?

Another TN member told me to do this and it really helped me out:

The book and DVD tell you to pinpoint by swinging the coil left to right to narrow down the area and then move the coil front to back across the target area to further narrow it down.

On my machine and others, the highest sound in pinpoint mode happen when the inner ring of the coil is closest to the target. Since the inner ring of the coil is elliptical it is larger front to back than it is side to side.

Instead of doing like they show in the book or DVD, first swing the coil back and forth to narrow the target are, then take a step to the side of the target and do the same thing 90 degrees from the first one. This allows the target to be pintpointed with the narrowest part of the coil in both directions. Doing this helped me out immensley.

The only bad thing is I can't remember who posted this tip so I don't know who to thank. Anyway, for whoever it was, Thanks. I'm pinpointing much more accurately now.

Hey Nat, there are other posts I've written about PP'ing with the 250 in the Garrett section........for here, tell your uncle to keep his eyes off the display. The worse thing you can do is train yourself to look at those bars. The first step in PP'ing with the 250 is understanding where the target is sounding off when it passes under the coil. You can't PP'ing something if you have not narrowed down its location with a machine that will PP in all metal mode. Unless you can get the best idea of where the object you want to PP is, you may as well end up PP'ing targets nearby. When you PP, the machine will PP anything, as it is in all metal mode. Back to the coil......when you swing over a target, on a left to right sweep, it will sound off when it passes the left outer coil and vice versa. Based on this fact, you should be able to narrow the location down by tightening the left and right swings and observing the outer coils when the machine sounds off. Once you do have that initial PP'ing skill in order, then you can start using the actual PP'er. Pick a spot in the middle, right around that little U will do and make that the center. Instead of going for precision, sweep carelessly to get an idea. Disregard the garrett site's advice about moving the coil forward and backward. Instead turn your body 90' and repeat the same. You want the smaller sideways length of the coil to do the PP'ing. Precision will come with practice. Precision can also come by re'pressing the PP button. I never used this at first, but have and it does work well. After the initial PP, let the button go and press it again. This "Detuning?" makes the objects signature smaller. Also, try not to PP with alot of sensitivity, especially with shallow objects. If you know or think that it's around an inch or two, go lower on the sens. This will make the objects field and signature while PP'ing even smaller.

Thanks Ricardo!! That is exactly the post I was refering to. I don't think I responded to the original post, but after I read what you wrote I tried it out and it helped me out a bunch! I forgot to add the part about disregarding the bars on the display while in PP mode. That is also excellent advice. Thanks again for the info!!
