Teknetics Delta 4000

The Delta 4000 gave beginners something most entry machines did not: a real target ID readout and adjustable discrimination on a detector that still cost entry money. It ran a straightforward layout with a large numeric display, and the multi-coil versions with the 8 inch round and 10 inch DD let a new detectorist learn what changing a coil actually does. Teknetics backed it with a five year warranty, which was unusual at the price.
