This search mode is exclusive to the Sea Hunter Mark ll. It is similar in operation to the Motion Discrimination mode in that it provides more precise and enhanced target discrimination. The background audio threshold remains at the chosen level until an “accepted” target is presented to the searchcoil. At that time a sharp audio response, a characteristic of all motion detectors, occurs.

As with the Standard mode, the Elimination Control is used to change the detectors ability to detect various types of metal; poor conductors can be eliminated while only slightly reducing the detection of better conductors. Although the Discrete mode appears to achieve less detection depth in air tests its ability to eliminate undesirable items precisely, without affecting desirable items, enables it to outperform the Standard mode in certain situations. For example, with the elimination control set to exclude pulltabs, they are excluded with little or no effect on the detection response to most thin gold rings.

To pinpoint in the Discrete mode, sweep the searchcoil over the target. The searchcoil must remain in motion to produce an audio response. This mode is designed to provide superior pulse induction target discrimination and is especially useful in areas with a lot of trash

OPERATING INSTRUCTIONS

The following procedure shows just how easy it is to operate the Sea Hunter Mark ll detector.

1.Turn on the detector and note the results of the automatic battery check represented by number of audio tones. Four tones indicate the batteries are good, two or three tones indicate they are adequate. When one tone or no tone is sounded, replace the batteries.

2.Select either the Standard or Discrete Trash Elimination operating mode.

3.Adjust the threshold audio level to the desired setting. Typically this level is set to the point that the threshold sound is just audible, barely above being silent.

4.Set the Elimination Control to zero or at least a very low level until you can determine the types and amount of trash metal is present. Eliminate only the minimum amount of items to insure that all acceptable targets are located to maximize your search goals.

Searching:

Scan the searchcoil at a speed of about one to two feet per second at a distance from the ground of about one to two inches. An audio increase will indicate the presence of metal beneath the coil.

Pinpointing and Target Recovery:

When the detector locates a target you must recover it to see what has been found. Pinpoint the target by making an imaginary “X” over the target. Where the loudest sound is, the target will be beneath the searchcoil. You may wish to switch into the Standard mode to enable you to hover over the target, because in the Discrete mode searchcoil motion is required to recognize the targets presence.

The final step is recovery and digging is usually involved. Always make as small a hole as possible and always fill your holes when the target has been recovered. Use the proper tool for the type of hunting you are doing. Recheck your hole for additional targets.

Batteries:

The Sea Hunter Mark ll requires eight (8) AA batteries. When replacements are required use only high quality carbon, alkaline or rechargeable batteries. Each time the detector is turned on

SEA HUNTER MARK ll specifications

The Garrett Metal Detectors Sea Hunter Mark II is a versatile underwater metal detector designed for treasure hunters seeking gold, silver, and other valuable items beneath the waves. With its robust features and advanced technologies, it has become a popular choice for both recreational and professional users.

One of the standout features of the Sea Hunter Mark II is its waterproof capability, allowing users to submerge the detector up to 200 feet (60 meters). This makes it ideal for beachcombing, diving, and exploring various aquatic environments. Its double-D search coil, which measures 10 inches, provides excellent coverage and depth detection, enabling users to effectively search larger areas for hidden treasures.

The Sea Hunter Mark II operates using pulse induction technology, which sets it apart from traditional inductive metal detectors. This technology allows the device to pierce through mineralized soils and sand effectively, making it particularly suitable for areas with challenging ground conditions. Pulse induction also minimizes sensitivity to saltwater, providing a stable performance in saltwater environments without excessive false signals.

Another notable characteristic of the Sea Hunter Mark II is its discrimination control feature, which allows users to differentiate between target types. This functionality is particularly beneficial when hunting in trashy areas, as it can help users eliminate unwanted signals from junk metal while focusing on potential treasures.

The device is equipped with a variety of user-friendly controls, including sensitivity adjustments and a visual LED target indicator. These features enhance the overall user experience by providing immediate feedback on the detected targets. The sensitivity control allows for fine-tuning to accommodate different searching environments, ensuring optimal performance.

In terms of design, the Sea Hunter Mark II is lightweight and ergonomically designed, making it comfortable for extended use. It also includes a comfortable armrest and a quick-release system, allowing users to easily adjust the length of the shaft for a customizable fit.

Overall, the Garrett Sea Hunter Mark II metal detector combines advanced pulse induction technology with user-friendly controls and a rugged, waterproof design, making it an excellent choice for those passionate about underwater treasure hunting. Its combination of performance and practicality ensures that treasure hunters can efficiently maximize their search efforts, whether on the beach or exploring the depths of lakes and rivers.
