The Delta 4000 comes equipped with an 8" concentric waterproof search coil, providing a practical balance of ground coverage, target separation, and maneuverability. Its large LCD display provides clear target information, depth readings, and battery status, while the numerical Target-ID system helps you evaluate targets before digging.
At approximately 2.3 lbs, the Delta 4000 is lightweight and comfortable to swing during extended detecting sessions.

8" Waterproof Search Coil
The Delta 4000's 8" concentric waterproof search coil provides a versatile combination of target coverage and maneuverability.
Its compact size makes it practical for detecting around parks, yards, fields, and other areas where targets may be close together. The waterproof coil can also be used in wet environments and shallow water.
Note: The search coil is waterproof, but the detector control housing should not be submerged.
Numerical Target-ID
The Delta 4000 features a 1–99 numerical Target-ID system that provides additional information about a detected target.
Combined with the detector's 3-tone audio identification, the Target-ID system helps you make a more informed decision about whether a target is worth recovering.
Discrimination & Search Modes
The Delta 4000 provides two primary search modes to accommodate different detecting situations.
Discrimination Mode allows you to filter out selected target ranges and reduce unwanted responses from common metal trash.
All-Metal Motion Mode provides a broader response to metal targets, making it useful when you want to search without rejecting specific target ranges.
Pinpoint Function
The built-in push-button pinpoint mode helps narrow down the target's location after it has been detected.
Pinpointing can reduce unnecessary digging by helping you determine where the target is located within the coil's detection area.
Large LCD Display
The Delta 4000 features a large, easy-to-read LCD screen that provides important information while you're detecting.
The display can show:
-
Numerical Target-ID
-
Estimated target depth
-
Battery status
-
Detection settings
-
Target information
Lightweight & Comfortable
At approximately 2.3 lbs, the Teknetics Delta 4000 is designed for comfortable handling during longer hunts.
Its lightweight construction makes it easy to swing across parks, fields, yards, beaches, and other detecting locations without excessive fatigue.
