The Teknetics Omega 8500 was introduced in 2015 and is still in production. The Omega 8500 is a 7.69 kHz VLF metal detector aimed primarily at coin, jewelry, and relic detecting.

"The Omega has a unique control interface that incorporates both analog and touchpad controls; adjustments are easy to make with one hand. The Omega has three graphics that display information about soil conditions: Fe3O4 bar graph, Ground Phase number and Ground Error indicator. These indicators keep you aware of the ever-changing soil conditions, allowing you to keep your detector perfectly balanced to achieve the greatest possible target depth. If you hunt in difficult soil conditions, the Omega is for you." Source: Teknetics website

I have never used an Omega 8500. I have read that it has improved EMI shielding.  I have owned the earlier version, the Omega 8000. The O8 is an excellent detector. I owned a version 4 with the 1/8" and 1/4" headphone jacks. This detector had two modes: all metal and discrimination. It reminded me a lot of the F19/Teknetics G2+ but at a lower transmit frequency and better audio features. Its major drawback was it suffered heavily from EMI interference at least in my area. It was impossible to turn the gain up above 50 even with frequency shifts and using the all metal mode was not pleasant due to all of the racket. In a more rural setting or with better shielding, this detector would be a joy to use. My experience with it was more of "I hope I will be able to detect with this machine today..........." only to find out that it was not possible far too many times.
