Teknetics Omega 8500 Metal Detector with 10" Waterproof Search Coil

Teknetics Omega 8500 Metal Detector with 10" Waterproof Search Coil

The Teknetics Omega 8500 is a lightweight, feature-rich metal detector designed for coin shooting, jewelry hunting, relic hunting, and general treasure detecting. Its combination of intuitive knob controls, convenient touchpad adjustments, computerized ground balancing, and detailed target information makes it approachable for newer detectorists while offering the control experienced hunters want.

Operating at 7.69 kHz, the Omega 8500 provides dependable sensitivity to a wide range of common targets. The large backlit LCD displays numerical target identification, target categories, estimated depth, ground conditions, and other useful information to help you make more informed digging decisions.

The included 10" waterproof concentric search coil delivers an excellent balance of detection depth, target identification, pinpointing accuracy, and ground coverage.

Advanced Ground Information

The Omega 8500 provides several tools for managing changing soil conditions. Ground Grab quickly establishes a computerized ground-balance setting, while manual adjustment allows experienced users to fine-tune performance.

The display also includes a ground-phase number, ground-error indicator, and Fe3O4 mineralization bar graph. Together, these features help you understand the soil and maintain stable performance in challenging ground.

Detailed Target Identification

The LCD provides a numerical target ID and visual target-category information to help identify probable targets before digging. The Omega 8500 also calculates secondary target information, giving the operator another way to evaluate inconsistent, irregular, or closely spaced signals.

Adjustable discrimination, notch control, tone selections, and category-based volume settings let you customize how the detector responds to unwanted targets.

Independent Gain and Threshold Controls

Separate gain and threshold controls give you more authority over detector performance. Gain adjusts amplification and sensitivity, while threshold establishes the minimum signal level needed to produce a response. This combination helps users tune the Omega 8500 for depth, stability, or sensitivity to faint targets.

10" Waterproof Concentric Search Coil

The included 10-inch round, open-frame concentric coil provides a focused detection pattern with accurate pinpointing and reliable target identification. Its versatile size offers efficient ground coverage without making the detector difficult to maneuver.

The search coil is waterproof and may be used in wet grass, mud, and shallow water. The detector’s control housing is not waterproof and must remain dry.
