NICKELS VS QUARTERS AND DIMES ON OMEGA

[CBAILEY IN GA]

I haven't gotten enough actual field use on the omega to really tell yet, but at home doing air tests nickels read loud and strong up to 10 inches and pinpoint pretty accurate with accurate depth. On quarters and dimes the omega tone gets a lot softer after 5 or 6 inches and the numbers get more jumpy also. Any one notice if it is like this in the field? Craig

Craig,My Omega does the same thing that you are talking about too.
It makes me wonder if I will miss a good deep dime or quarter because
of the tone being so faint on it. Gary

Craig, by that I mean some might look at it as the Quarters and Dimes are "softer' or "weaker" than the response to a Nickel.

On the other hand, you could consider the response to Pennies, Dimes, and Quarters as "typical" or "average" while the Nickel coin responses are simply a 'BONUS."

Questions:

1.. Are you sure you "air tested" the Omega with the coins held "flat-to-the-coil" when you passed them across the coil's center?

2.. Did you do the "air test" with the Omega simply turned, or did you do a Ground Grab to set it for typical Ground Mineral conditions?


Comments:

A.. For the record, it is quite common for some makes and models, due to their operating frequency, method of target processing, and the alloy make-up of a US 5

Wasn't sure about changing any settings as I was doing testing indoors, which probably isn't good either. Testing was done with 11 in dd coil not sure of the settings (ground phase) had disc on with just iron disc out. used a card board box with wooden ruler pushed in at different depths. ran coil across top of box so sweep was perfectly flat. Not downing the 8000 just an observation and really is a bonus for me as I want to find more gold than anything else at freshwater beaches and some saltwater 2 times a year. I may try again outside and ground balanced with the box and also try it 8 or 9 inches in my test area also and see how it compares. Craig

It's good to "test" with various settings of sensitivity and Discrimination, and different operating 'modes.' Also, I think most people come to the Omega from other brands/models and tend to prefer the 3 or 4 Tone audio ID. I know I like to use d4 a lot of the time, but it depends upon the particular site I am working, the trash level, and what I am after. I really prefer d2 in the Discriminate mode, as well as the Auto-Tune All Metal mode.

The "turn-on" Ground Phase of the Omega is '82' which is rather high. If your area typically calls for a GB setting that falls in a certain range, like '66' to '70', you might want to drop the GB manually to match the GPR (Ground Phase Read-Out) of your area.

Now, this might sound peculiar to some, but even if you use a cardboard box and stick a coin in the side at a measured depth (I presume this is what you did), you can get impaired performance depending upon the coil used and the direction you sweep the coil. I can guarantee you this will get a lot who chuckle and question such a statement since it's a cardboard box, but I have demonstrated this through the years.

Yes, I know that we should be able to detect through water and glass and paper and cardboard without too much effort, but ......

The reality of it all is that all matter will have an affect on an electromagnetic field to some degree. For example, you can determine the maximum depth (distance from the coil) that you can get a signal on a particular coin. Let's say that 9

Thanks Monte for your in depth responses. Having people like you on the forums is a real big help, especially for new mder's like myself. I've only been detecting since November and it's like on the job training, learning as you go. But with the Omega this year I am hoping to have a real nice year. Thanks Craig

but OJT IS the best way to really learn what works best for you at your hunting locations. You should eventually and more importantly learn "the whys" in addition to just "the whats". Relax, pay your dues, have fun and be patient as the learning comes, and you will be rewarded handsomely with finds and the joy from your expertise while pursuing this hobby.

Great advise.
