The Teknetics Delta 4000 was introduced in 2008 and was discontinued in 2019. The Delta 4000 is a 7.69 kHz VLF metal detector aimed primarily at coin, jewelry, and relic detecting.

"The Delta has multiple Notch capability, one-touch Pinpoint Mode and numerical Target-ID for more precise target identification. It has Discrimination and All Metal Modes and an active on-screen bar graph depth indicator. Easy to use with more features than any other detector in its class." Source: Teknetics 2014 catalog

The Delta has many very good features. Unfortunately it could not cope with either the bad EMI or high mineralization in my area. I'm sure that in milder soil mineralization it would be great.
