Product Description

The Fisher 1280-X is designed for serious detectorists exploring underwater, beach, or shoreline environments. Ideal for scuba divers, surf waders, and relic hunters, this rugged detector stands out with its ability to operate fully submerged to depths of up to 250 feet. Its true plug-and-play simplicity means no ground balancing is required—just turn it on and go.


Operating at a low 2.4 kHz frequency, the 1280-X provides excellent sensitivity to coins, jewelry, and relics, even in salty or mineralized conditions. The built-in discrimination control lets users filter out trash while maintaining strong responses on valuable targets. A waterproof, concentric searchcoil is paired with slow-motion target detection, allowing for precise pinpointing. LED target indication and custom-designed piezoelectric headphones ensure clear feedback in any environment.


Crafted with an ABS fiberglass-reinforced shaft and durable epoxy-filled coil, the 1280-X is engineered for long-term use in wet, rugged environments. It’s lightweight enough for extended hunts, and the hipmount configuration option reduces fatigue during long sessions. With up to 80 hours of battery life on standard AAs and simple, intuitive controls, it’s ready whenever adventure calls—on land or 200 feet below the surface.

    Frequently Asked Questions

    What type of metal detection technology does the Fisher 1280-X use?

    The 1280-X uses VLF (Very Low Frequency) technology operating at 2.4 kHz, quartz crystal-controlled. This low frequency is optimized for better sensitivity to larger, deeper targets and minimizes saltwater interference.

    Is the 1280-X truly submersible, and to what depth?

    Yes, the entire unit—including the control box and headphones—is fully submersible to a depth of 250 feet (76 meters), making it ideal for scuba diving and deep underwater detecting.

    Can I switch coils on the 1280-X for different search applications?

    No, the coils are not user-interchangeable. Each unit is factory-calibrated to a specific 8” or 10.5” concentric coil. However, Fisher offers a retrofitting service if you want to change coil sizes.

    How does the 1280-X handle saltwater interference?

    The 2.4 kHz operating frequency helps reduce conductivity noise from saltwater. Additionally, lowering the sensitivity and increasing the discrimination to foil-level will further stabilize the detector in turbulent saltwater conditions.

    Is ground balancing required on the 1280-X?

    No. The 1280-X features automatic ground balancing, which continuously adjusts to changing ground conditions without user input—especially useful when transitioning from dry sand to wet sand or underwater.

    What is the target response audio system on the 1280-X?

    It uses pulsegate unipolar audio processing with a fixed 400 Hz tone. This allows for silent operation below the audio threshold without sacrificing sensitivity, making it easier to isolate faint signals.

    How effective is the discrimination system for separating targets?

    The discrimination control offers a full range from 0 to 10. At lower settings, all metals are detected; as the dial is increased, common trash items like foil, pull tabs, and nails are filtered out. However, increasing discrimination can result in slight depth loss, especially on smaller gold targets.

    Does the 1280-X have a pinpoint mode?

    While it does not have a dedicated pinpoint button, the 1280-X allows for accurate target localization by narrowing sweep patterns and adjusting coil movement—thanks to its slow-motion detection circuitry.

    What type of headphones does the unit use, and are they replaceable?

    The 1280-X includes permanently attached piezoelectric waterproof headphones designed for submersion. They are not user-replaceable; if damaged, the entire unit must be returned to Fisher for service.

    What kind of battery life can I expect, and does it support rechargeables?

    With 8 standard AA alkaline batteries, you can expect 60–80 hours of operation.
