I have used my Omega for less than a month and have made some good finds with it. Most of these good finds have came from very trashy parks and fairgrounds and every time I got a wheat penny or silver coin I was surprised. I wanted to figure out the depth limits of this detector and it is hard to do while hunting trashy spots. I originally thought I could hear a deep signal better in one tone, but today's outing made a liar out of me. I went to a school that was closed in 1976 and has been in private ownership since that year. I got permission to hunt this old school four years ago and usually frequent it about twice a month. The back of the school is about two acres of mowed grass and believe it or not, it contains very little pulltabs and modern trash. I have found about 50 silver coins and many wheat pennies, most being with Explorers. These coins all are over 8 inches deep. It is an easy place to hunt with the short grass and lack of trash so I have hunted with little discrimination with any detector I have used here. It is a great spot to find out if a detector has enough guts to get to the coins. I last hunted here with my Etrac a couple of weeks ago and found 8 wheats, an old merc, and two buffalo nickles. Today I took the Omega and figured I could not consistantly get to the depth of these coins. I hunted for over an hour and a half and had only found one 1972 penny from 5 inches deep. I experimented with the tones, disc, and sens, but I could not get a signal that was deep. I was about ready to give up so I went to the area where I have found most of the older coins. I was in one tone and was hoping for a signal that I knew was a coin and was deep. Finally, I got that signal and I started playing with the settings. I got a quick, round blip in one tone that had a number of 82. I put it in three tone and got a faint, but disticnt high tone with a low 80's number. The depth gauge showed 6 inches. When I dug the plug, I was being very careful to not exagerate the depth. I finally found a green wheatie that was an honest 8 inches deep! Not a strong signal but a weak repeatable high tone. My confidence in the Omega was rejuvenated. I now started listening for identical signals and withing 5 minutes I got another similar signal. Another 8 inch deep wheatie. Shortly after I found a double sterling silver heart pendant from over 8 inches. One thing I have noticed is the depth gauge on the Omega almost always read shallower on deep coins. In other words, a eight inch penny will read 6 inches on the gauge. I believe that in my soil, I can get 8 to 9 inches of depth on a penny-dime and that is good to know. Add this type of depth with a fast response time and it makes for a nice detector. One other note, while in three tone mode, the deep coins were not at all loud so it is my opinion that a good set of headphones is a must. I use Killer B Hornets and they work well with the Omega. My final settings: disc 15, sensitivity 75, three tone, with a ground reading of 65. I could not get the detector to run stable over 75. I dig very little rusty iron with this detector, alot less than I do with my Explorers and Cz's of the past. It does like rusty bottlecaps. The deeper ones will high tone with numbers all over the place. Shallow caps will read a consistant 84 to 86 and high tone from all angles. I guess there is no perfect detector and even my Etrac is fooled by deep screwcaps or maybe I should say I am fooled. R.L.

Depth On The Omega
- Thread starter RLOH
- Start date
I always use 3 tone and if you want depth you have to turn the sense up past the last blue rectangle, when you are in a area were the Omega want run stable take the disc knob on the right side turn it up as far as it will go and you can cherry pick silver,now with a omega it will get a silver dime 9" and a silver quarter at 10" with the 11`DD coil now a lot of the time it will only be a 1 way hit because its at its extreme limits on depth,this is why you use 3 tone in 3 tone when your are swinging the coil and you get a hit you stop and check it out if its 1 way and deep then its usually silver. if you Don't turn the Omega up Blue rectangle (gain) you want hear any deep dimes.HH

To get the most depth, I run in AT. You won't have a tone ID, but there have been many times when I've gotten a signal in AT but nothing when I switched over. For what it's worth, I found two crushed soda cans at a measured 16 inches yesterday.

Good post and congrats on the 'deeper' finds!
As Cache man pointed, out at times EMI can be lessened with higher disc setings. While I have not run the disc all the way up, increasing it into the 16 to 40 range can lessen EMI for me at sites where it is a problem. Once you hit the 80 area on sensitivity the loudness of deep targets increases somewhat, you still get the modulated audio, it just runs at a 'deeper' depth.
With the DD coil I get accurate readings in the 8"-9" range in my ground and that is running a bit hot on the sens.
On the shallow to mid depth bottlecaps, trying sweeping the front or rear edge of the coil over the suspect and you will immediately see iron numbers come in, usually 39 shows up on them in my ground. It is an almost foolproof method of id'ing the pesky things. I'm confident enough in this that after digging many bottlecaps I ignore the louder 80's hits that drop to iron sweeping them this way.

Hi Jackpine thanks for the lesson on how to id a bottlecap, i think that will help a lot of us and i will try to remember your suggestions on that the next time i go out with my Omega.I find bottle caps also lol but one thing i have found is the Omega seems to love dimes i also hunt a large park close to me and my ratio of dimes to other coins is very high.Good luck and hope everyone has an enjoyable weekend...Markmac
Jackpine Savage one thing i forgot to ask you about your tip about id bottlecaps,will that tip work with the standard concentric coil as well as the 11inch dd coil.Your post didnt mention which coil you were using so i was just curious if this tip works with any coil on the Omega..Thanks ..Markmac
I don't mean to step on Tom's toes by replying, but the answer is generally going to be 'YES,' it works with a standard concentric coil. I started using this technique back in the late 70's with our early motion-based discriminators. There are two techniques that I found worked well to "classify" typical iron-based (magnetic-based) targets as "Iron" as they were with the older, conventional TR-Disc. models. Motion discriminators, all of them, face some challenges dealing with the bottle caps.Markmac said:
I have posted on several forums through the years the two techniques, which I coined labels for as "Quick-Out" and "EPR" (Edge-Pass Rejection) since I started teaching them in the early '80s. Concentric coils often do a better job, actually, because Double-D coils do not discriminate quite as well as a concentric coil. In both cases, concentric or wide-scan (DD), you have to learn were, in relationship to the front or rear 'edge' of the coil, your particular detector and coil work best.
One word of caution and that is these types of techniques work reasonably well on relatively shallow targets. I can usually trust the results when trying to classify a potential bottle cap from surface to 3" and maybe 4". Beyond that, however, it becomes more 'iffy' and then best call is to recover the target.
Just my thoughts.

Hi Monte,Thanks for the reply and as always i personally enjoy reading all your points of view and the sharing of your knowledge.Its nice to know that the standard concentric coil works with that technique as for now after using the std coil the first week then switching to the 11inch dd and using the 5inch a few times which is a nice coil i seem to prefer the std coil myself for hunting the large park i live by, that may be due to my lack of knowledge or experience with a dd coil or could be the cencentric just clicks better with me for some reason.I was so looking forward to using the larger dd coil after all that has been posted about that and im sure maybe for relic hunting it would kick butt lol but i mostly just coin hunt here in Illinois and i did not feel it did any better then the std coil yes it will go deeper but as far as finding more coins with it i have not flound that to be the case YET but i will work with it more to learn as much as i can about the larger dd coil but i must say that std coil is very impressive in my personal opinion.I have found that the Omega loves dimes at least in my ground here it seems to hit hard on clad dimes.the ground usually balances at mid to upper 50s disc just to get iron out and sens settings around 80.Im going to use the standard coil thgis weekend then put the 11inch dd back on and try that for a few more days as well.best of luck to everyone...Markmac
