Here's another question for anyone interested in fielding it - [size=medium]is the Gamma really noticeably superior to the Delta and how?[/size] I am sure this may have been covered here in teh past but if anyone wants to throw out their opinion I'd be glad to hear it.
I have a Delta. I like the Delta. It is an easy-to-use, turn-on-and-go model that I might grab for some casual coin hunting, but is mainly a model I like to have for friends or family to use as a loaner.
One thing that I like to have, when trash isn't abundant or when working places like thick wood-chip playgrounds, is the saturated audio the Delta works with.
Another thing that people who use it like is the simple Discrimination settings which either accept or reject categories of targets. Also, the Sensitivity adjustment is also easy to make because it is broken down to 9 categories from '4' to '12'.
Now, with that said, here are some reasons I prefer the Gamma or Omega, and maybe you would say these are more 'advanced' adjustment picks for a more avid detectorist. They are:
* Variable Discrimination from '1' to '80' so you can fine-tune the set rejection point on both models.
* More adjustable Sensitivity, going from '1' to '99' on the Omega, or 'stepped' settings in increments of five from '5' to '10' to '15' and so on with the gamma up to '90' Then it can be increased one at a time to '91', '92', '93 and so on to '99'.
* User selectable Tone ID. Both the Gamma and Omega can use a '3' or '4' Tone ID audio ([size=small]the Delta is '3'[/size]) which some like for average coin hunting ([size=small]my pick is '4' Tone ID[/size]), but they also let you chose between a '1' Tone for ALL targets, ferrous or non-ferrous, or the '2' Tone ID method which produces a lower bass-like tone on most Iron and a higher pitched tone on non-ferrous targets ([size=small]I prefer the '2' Tone ID option most of the time[/size]).
* A little more display info, such as a Ground Phase or Ground Balance read-out, and the Omega has more display than the others.
* Both the Gamma and Omega feature the Ground Grab automated Ground Balance function as well as manual Ground Balance. The Delta is a factory preset setting.
* The Delta is a saturated audio design, and the Gamma and Omega have a more processed modulated audio in '3' and '4 Tone ID, and excellent modulated audio in the '1' and '2' Tone ID selections. Thus, they can hunt deeper than the Delta because you can hear some weaker, fainter target responses.
There are a few reason I think the Gamma, or Omega, have some noticeable superior performance to the Delta.
