I got what I asked for with the Omega

When researching a new midpriced detector I stated I wanted a detector that would accurrately TID a coin at 6". Yesterday I got my deepest coin yet. It was a quarter at 6" with a locked on 88 reading. I found 9 quarters yesterday and none were "state" quarters at a football field. From shallow to 6". I was also in the most mineralized ground I have tried with a 53 GB. I am sure in better ground it will go deeper. I was using disc about 10 and 85 sensitivity and 4 tone.
I am happy.

I also discovered something not so good. My hearing loss does affect my detecting ability. It was quiet where I was at and I barely heard the high tone. I don't stare at the screen as I detect. If it had been noisy I would have not heard it. I have probably missed targets in town because of this.

It looks like I will need to get some Black Widows when It cools off. I have heard these headphones are the best for getting the quiet signals thru. No way could I use full headphones in this heat. I am currently using Koss lightweight headphones. It was close to 100 degress by noon here. I made it till 11:30.

I need to hit Goodwill and find a old walkman cassette player and make a amplifier for my light headphones. I saw a article telling how to do it and it looked simple enough. It is basically removing the tapehead and running a wire with a plug from the detector to the tapehead wires. Also cut the wire to the tape motor. Plug your headphone into the jack on the player and you have a amplifier with volume control.

I have a few weeks to do it because tomorrow I am getting a hernia repair done. Looks like I ripped a stitch from Octobers cancer surgery.

You're right about headphone selection for the Omega and Gamma. The great modulated high end audio will be wasted with phones that have a low output. Jolly Rogers originals aren't a good match and I speak from experience. In your post you mentioned having trouble hearing the real weak high tones. I'm not sure if you referring to actual good target response or iron falsing. One thing I've noticed is when you're running a little hot on sensitivity and especially this time of year when it's hot and relative dry, sometimes the falses will trigger a high numeric ID and seem to not have any audio. I'm not sure if there really isn't any audio or it's just too low to hear. Less sensitivity will usually eliminate this. It seems with these Titaniums series detectors, the ID depth and maximum depth are closer to the same compared to the T-2 for example.

Hi BuckeyeBrad,

The high tone I almost missed was a good target response. I have been doing bodywork for around 33 years and my hearing has suffered from it. Surprisingly the ground is still moist here due to the thunderstorms we get every couple of days. The Omega was very stable at 85 sensitivity at the football field. In town about 65 or 70 is all I can get. There was no jumping or noise when I laid the detector down. I was working a group of trees close to the concession stand in the shade of course. When I had worked close to the gym earlier I had the sensitivity somewhere around 70 due to EMI. I like the Omega more as I get used to it.

I have been running low disc as I seem to find more by hearing iron mixed in. I did stop trying to be NASA-Tom by using disc 16 lol. At this stage I need to learn my detector better before I try to be a professional. In the coming months me and the Omega are going to become close friends. I also found I like 4 tone the best so far as nickel has its own tone. I found 2 nickels yesterday and of course tabs.

Question? Which will have a tendency to cause more falsing, too negative or too positive ground balance? I have found that after I fast grab in AT when I swing in disc I usually get 2 to 3 bars on the top of the GB graph. Yesterday I manually dropped the GB till it was pretty evened out when swinging. The detector seemed not false as much. I had to drop to lower numbers. Maybe my dirt is hotter than fast grab says it is. Also it might be because it is hard to find a place in AT to balance at and sometimes all I can find is a small spot.

Thanks for the tips, they are appreciated.

As you've already discovered, you can quiet down the detector some by offsetting the GB to the negative side but if you do it more than slightly, you'll also be losing depth and response to smaller targets. You might want to experiment with this and you'll quickly see the cause and effect. As for the ground error meter showing bars in the positive range...any target will do this and if you're getting fairly rapid and regular targets as you swing, the error will be showing positive bars virtually constantly even if the GB is spot on. It takes a little while of swinging over target free ground for the error meter to show up accurately. In other words, if you haven't heard any targets for say 5 to 7 seconds, then the meter should be accurate. Again, experiment and observe the cause and effect.
