Teknetics Delta 4000

The Teknetics Delta 4000 is a feature packed metal detector designed for the serious hobbyist. It features a large LCD screen and an advanced interface. In Discrimination mode, one can use the large numerical Target ID readout as an accurate reference point. A depth meter is also highly visible on the display, constantly showing approximate distances of targets on a 5-segment scale.

The dedicated Pinpoint button on the touchpad allows the user to quickly narrow down the exact location of the target object. This static pinpointing mode gives you more accurate feedback without having to sweep the coil constantly. It can detect a coin sized object down to 11 inches from the coil when the detector is set to maximum sensitivity. There are also two All Metal modes labeled A1 and A2, both of which are designed to provide maximum sensitivity. Sensitivity and discrimination levels can be manually adjusted through the onscreen menu.

The Delta 4000 comes with an 8-inch search coil which is fully submersible underwater. Its rated operating frequency is 7.8 kHz, while there are also 1st and 2nd order frequency selections on the control menu when electromagnetic interference in the environment causes problems with the detector’s performance.

Using the recommended 9-volt Alkaline battery, one can expect anywhere from 20 to 25 hours of use. Headphone jacks are also provided for a more focused listening environment.
