Discrimination Points

By adjusting the DISC (“Discrimination”) control, you will be able to ignore or (“reject”) small pieces of metallic target trash and ground minerals while detecting valuable targets. The lowest setting at which an object is rejected is reffered to as its “discrimination point.” Discrimination points are determined by such factors as size, shape, depth, type of metal and ground mineralization.

1.Scatter some sample targets such as coins, pull tabs and small pieces of foil on the ground 1 to 2 feet apart.

2.Turn the 1225-X on by turning the DISC control to zero.

3.Set the SENS control to 8.

4.Hold the search coil in the air, away from any metal objects and check the batteries as explained in the Control Function section (sensitivity control).

5.Hold the search coil in the air about 2 inches above and parallel to the ground. Move it slowly over the samples and note the sharp loud response as you pass over each one. Keep in mind that the 1225-X is a motion detector in the DISC mode and responds only when the search coil (or the target) is moving.

6.Increase the DISC control to a setting of 3 and again pass over the targets. Repeat this process at settings of 4, 5, 6 and so on to 10. You will note that as you increase the level of discrimination, the 1225-X will reject some targets and continue to respond to others. You have now determined the discrimination points for the rejected objects. For example, the small nail discrimination point may be at 3 and the pull tab discrimination at 7.

7.Some objects such as shallow bottle caps, bent pull tabs or trash less than 2 inches from the coil may be difﬁcult to reject. The 1225-X will instead respond with a broken signal which will usually disappear if the search coil is raised slightly. The strong signal of a good target will usually get weaker when the coil is raised.

1225-X specifications

The Fisher 1225-X is a highly regarded model in the realm of metal detectors, known for its durability and advanced capabilities. Designed primarily for treasure hunters and enthusiasts, this metal detector showcases a blend of user-friendly features and cutting-edge technologies that enhance the overall searching experience.

One of the main features of the Fisher 1225-X is its lightweight design, making it easy to maneuver for extended periods. Weighing less than many of its competitors, it allows users to explore various landscapes without experiencing fatigue. The adjustable shaft further adds convenience, catering to users of different heights.

This model is equipped with an impressive discrimination capability that allows users to filter out unwanted metal types, such as iron and aluminum. With its multi-tone audio feedback, the 1225-X provides users with distinct sounds for different metal types, enabling quick recognition of valuable targets. This feature is particularly useful for those who want to focus their efforts on more valuable finds.

The Fisher 1225-X operates at a frequency of 5.3 kHz, which enhances its sensitivity to larger and deeper coins while effectively detecting smaller objects. The 10-inch search coil is waterproof, allowing for use in various conditions, including shallow water searches. This versatility makes it an excellent choice for treasure hunting in both dry land and underwater environments.

Another standout feature is the ground balance adjustment. This allows users to calibrate the detector to different soil conditions, minimizing false signals while maximizing target detection. The automatic ground balance feature simplifies this process, making it accessible even for beginners.

Furthermore, the Fisher 1225-X includes a visual display that shows target depth and type, making it easier for users to assess potential finds before digging. The headphone jack enables users to connect audio devices, providing a more immersive searching experience.

Overall, the Fisher 1225-X has established itself as a reliable metal detector, combining practicality with advanced technological features. Its user-friendly interface, adjustable settings, and robust construction make it a preferred choice for both novice treasure hunters and experienced professionals alike. Whether searching beaches, parks, or historical sites, the Fisher 1225-X offers an enjoyable and productive metal detecting experience.
