A couple questions.....

[Old Katz]

1. There is a 9x12 coil for the Ace 250: Has anyone used it? I hear it ads a bit of weight
to the machine and tends to tire one out.

2. Some other posts mention "twitching" moveing the coil over a target area faster than usual
and getting deeper targets. I wonder if this might help me to get deeper targets in the fields, with
the 9x12.

3. What is the deepest target with the 9x12 coil in relic mode, or should I think about keeping it
in all metal instead?

I don't have the 9X12 but with my stock coil I have found targets down as far as 10 inches. If I am looking for relics I hunt in the all metal mode! Just my 2 cents!!

All the various modes do is turn notches on and off. It doesn't do anything to affect depth. You'll get deeper with the big coil. I am just discovering how much I like mine using my 2500. It has really helped me find more silver. Twitching is a technique UW describes and quite probably invented. Here's how I use it. When I get a one way signal, I pinpoint it and then move the coil quickly back and forth in a very tight pattern over the spot. The signal will usually ring up both ways and more steadily on one or two notches when doing this. If the signal rings up in the coin area of my display or bounces between a low notch and a coin notch I dig it. It is frequently a deep coin. It is also frequently an iron nail or some other junk. Gotta take the good with the bad. I have not had much luck where a deep iron signal has been a coin but others have said they have dug deep silver coins that indicated iron.

I find that the better I get at detecting the more deep stuff I dig. It takes practice, but a bigger coil doesn't hurt your chances either.

My three cents.

no 1 yes it"s a little heavy-er .
no 2 twitching is for deciding if an iffie signal is worth digging or not, if you twitched a whole Field or park ya may get a sore arm .
no 3 i run all metal i don't gain depth but i do gain valuable target info which i"d miss in disc.

Thank you.
I'll gtive the "Twitch" a try.-)

Deep target good sign pinpoint and then stomp ground on pin point spot this send a small tremor down and usually breaks target away then take another reading usually tell you what it is.Also if you walk around target and it is mixed with other targets you can usually start to separate it once you find the bell tone work on it and if it is good it will usually start to come out over other targets.Hope this helped some.

The 9x12 is quite naturally heavier as it's a larger coil but it will get you another 2-3 inches in depth and covers more ground when hunting large areas.

Since you are using a "motion detector" the faster you move the coil the deeper it goes and the better it discriminates. Twitching is a method to turn bad signals into good ones. Just center the coil over the target and whip it rapidly from side to side about 2-3 inches each way.

What mode to hunt in is entirely your decision and depends on what you are hunting.

Good post Chris. Well worth your three cents....
Certainly a good technique to use in the field.
I'll take any advantage I can get, They all add
up in the end. Good hunting to you ! Gene

Forgot to say, many corroded coins, especially if not laying flat, will give a broken or iffy signal and twitching will eliminate that and produce a diggable signal. Even tarnish or patina on a coin can often effect the eddy currents generation on the surface of the target..

Yeah I've recovered quarters at ten inches in damp bark chips.
