Is it normal for the Omega to give an overload signal on a pull tab at 1 inch?

[Mick in Dubbo]

Just trying to figure out whether it's operating normally and whether it's just an over sensitive detector. It can give a partial overload signal at almost 2 inches on a pull tab and even more easily gives an overload signal on almost all our modern Aussie coins at 2 inches, except for the lowest possible sensitivity setting, and even then on big coins. I sent back my first Omega just after I got it due to other defects and pull tabs and coins reacted the same as the current Omega I have, so I'm not sure of what is normal behavior for the Omega.
Your input will be muchly appreciated.

im also thinking of sending my omega back..mine overloads easily too. it may just be that is has so much power??? mine is extremely sens to emi. i have to turn sens down to 50 or so in order to hunt. it may be one heck of a deep machine..im gonna do some more testing today to see if i can learn more about it.

I only get overloads on larger objects. It would be interesting to air test your unit and see if it's extra sensitive (deep).

Also, I don't have problems with my Omega and EMI like I did with my T2. I can run my Omega in the house at 50-60 sensitivity. In the field I open it up to 99 with no discrimination. It is only chatty when not moving or when the ground is wet.

Thanks guys.
I decided to phone the Aussie dealer hear. It's unclear as to whether it's normal or not, but I'm sending it in so that it can be checked out. Hopefully, it's as simple as adjusting an internal adjustment pot.

Mick, just saw your post. It doesn't sound right. Sometimes I get an overload on a small target on the surface, but not usually at 1" and definitely not coins at 2" depth. Hope they can sort it out for you.

You didn't mention the settings or the search coil used. Also, you said it gives a 'partial overload' at almost 2". By 'partial' do you mean it only overloads on occasion? Are you sure the measurement is 2 inches and not a different classification? Also, how big are your Aussie coins, physically, and their alloy?

I sent back my first Omega just after I got it due to other defects and pull tabs and coins reacted the same as the current Omega I have, so I'm not sure of what is normal behavior for the Omega.

If pull tans and coins acted the same on your first Omega as on this current one, it would seem that it could be 'normal.' Remember, the search coil is supposed to be worked about

Yeah. I was getting that impression when I read your post. I looked up some u-tube vids to see if that could shed any light on it. it seems that that confirmed what I suspected.
Monte. I varied the sensitivity and lowering it didn't seem to make much difference, even down to the 30's and 20's. I was using the standard coil.
We do have a couple of modern coins that are around the same size as your large cents (20c and 50c). At first I thought the same as you, in that if both Omegas behaved the same way, then that would be normal, which is why I have only used it once in the last 3 months.
Unfortunately, we only have one Teknetics here in Oz. It's 800kms (500 miles) to the south and if I thought that the oversensitivity of the Omega may be a fault, then I could have made a minor detour when I passed though that part of the world (Victorian gold fields) 9 days ago. the second draw back is that they are all gold hunters, so their coin hunting knowledge is very limited. I sent the detector off only a few hours back, so hope to get some resolution to what is going on. Hopefully, I've just been a bit unlucky.
