Omega and NEL Hunter coil.:teknetics:

[jim tn]

Just recently re-acquired another Omega. Had let my first one go. This one seems to be vastly improved with emi issues that I frequently had with my first one.

Anyway, I had ordered it with the 10" concentric and 10" DD coils and wanted a larger one so opted to give the NEL Hunter coil a try in hopes of some extra depth. Of which, it seems to have. I took the coil out this morning on its maiden voyage and to a spot that I like to test new detectors and coils on. A hard hit old military housing site that the homes were all demolished back in the mid 80's and then donated to the city and they turned it into a park. Needless to say, it is one trash laden spot and one I have hunted countless times since retiring in 2006.

I spent about 3 1/2 hours on the spot this morning. About half the time hunting along foundations and the other halve hunting both sides of a ditch and was more then pleased with my results. 1 of the 2 wheat cents, a 191?, came out of the ditch and was all of 7" deep. The 45 darkened Mercury also came from the bottom of the ditch and was a nice 6." The other wheat, a 55d, came from near a foundation and the 52d Rosie a couple of feet out from a foundation. The medal was about 5" and on edge. Front says U S S and Valley Forge. Reverse, Volley Ball INT DIV Champions March 1951 (and a word on the bottom I have to work more on to get). 1 10 cent play money piece, a toasted truck and a small lock round out the most notable of my finds.

It is good to be back on the Tek fourm. HH jim tn

That ole site just keeps on giving. Nice going in that trash dump.

Jim have you tried the NEL Sharpshooter coil on your new Omega?

Tab, I don't have a Sharpshooter for the Omega. Just for the A T Pro. You may remember I really liked the performance of the Tek 5 x 10 DD on my other Omega and in that size range, that's the one got I and am using. HH jim tn

Jim I have used both coils on the Omega and the Sharpshooter coil handles the EMI better. If you want to try my Sharpshooter on your new Omega, you're welcome to it.

I have the hunter and sharpshooter. Both a little deep in center in exchange not as tight vdi on toe and heel. Definitely top notch build and emi resistance. I pulled two quarters at a true 8" in 3 tone, 70 disc w/nickel notched in. Super trashy park with bad emi. Was quiet and at 56 sens (80% max gain).

.. your included information about the detector settings and explaining the coil's areas of response.

I have the hunter and sharpshooter. Both a little deep in center in exchange not as tight vdi on toe and heel. Definitely top notch build and emi resistance. I pulled two quarters at a true 8" in 3 tone, 70 disc w/nickel notched in. Super trashy park with bad emi.

I found the build quality and field performance of a Sharpshooter to be better than some factory and other aftermarket coil builds I have seen. I haven't used the Hunter size yet.

Was quiet and at 56 sens (80% max gain).

Except this one throws me a little because the '80% max gain' you mention with a setting of '56' would be based on a 100% gain of '70.' A '70' setting is suggested in the Owner's Manual as being close to the slight audio hum Threshold level setting in the Auto-Tune All Metal mode. As explained in the manual, a Sensitivity setting up to '70' is a linear adjustment, but from '71' on up some internal noise can be heard, and this is primarily referenced to the Discriminate mode function..

This is somewhat like adjusting a White's M6 or MXT Pro above the factory preset level, or a Tesoro above the 'preset' and into the 'Max Boost' Sensitivity range. Maximum or Full or Total anything is 100%. You can not adjust above maximum on anything because 'maximum' IS 100%

An Omega, operated at a Sensitivity setting of '99' is at 100% Sensitivity level. I generally search at 'full' Sensitivity with the Omega at '99' but, if surrounding conditions challenge me with too much EMI and chatter or static, I reduce the Sensitivity just to the point of stability. So an 80% of full-Gain/Sensitivity would be '79' [size=small](79.2)[/size], or 80% of '99'. It might be noisy in some environments, but that would be 80% of a maximum Sensitivity setting. A '56' setting would be 80% of the linier scale range and, usually, that would provide quieter operation in a noisier EMI environment.

If '70' was the absolute high Sensitivity, then a '99 setting would be 29 numbers or 41.28% higher than '70', and you can't have 141.28% = "maximum" because "maximum" would be 100% Now I know there is some transition after the 'linier' range, but it is still in the order of Gain/Sensitivity adjustment, and regardless of it being all linear or a blend of scales, '99' is still the 100% "maximum" Gain setting. I guess your reference of 80% at '56' Sens. would be correctly described as 80% of the Linear scale, not 80% of Max Gain.

I still feel the Omega is the best all-purpose detector in the whole Teknetics line and it is my favorite Teknetics model. And, again, 'Thank You' for the details in your post.

[size=small]PS: On the Omega, while I like the stock elliptical 5

I gotcha. Yeah I think of 70 max gain and then 71-99 threshold increase. This was with hunter. Although even the SS and stock coil could not go over 60 sens quietly due to EMI. Love the nel's but there is some target id behavior differences. Some good some not so good.
