Search Modes

Raise searchcoil approximately one foot above the ground. Rotate this knob to turn the detector on and the detector begins operating. Each time the detector is turned on the battery condition is reported audibly. Three or more tones indicate the batteries are very good, two tones indicate the batteries are adequate. One tone or no tone indicate the batteries need to be replaced.

Audio:

This control on the lower left of the detector panel allows the operator to adjust precisely the level of sound generated by the detector. It is suggested that this sound level be adjusted to a threshold level where it is barely audible when searching.

Elimination Control:

Located on the upper left of the detector faceplate panel. Used with either of the two Trash Elimination modes to choose the level of trash rejection appropriate to your search needs. As the control knob is rotated clockwise more items are eliminated from detection.

Headphone Jack:

Located on the upper right of the detector panel. Underwater headphones are included with the detector.

Standard Trash Elimination and Discrete Trash Elimination are the search modes available on the Sea Hunter Mark ll. The selector switch for these modes is included with the Power Control on the lower right of the detector panel.

Standard Trash Elimination:

This is the search mode normally available on conventional pulse induction (PI) detectors. In this mode the background audio threshold is continuous and remains close to the level established by the operator. Some slight variation of the audio level is normal. Small or deep targets produce faint and weak signals; large or shallow targets produce loud, strong audio signals.

The Elimination Control, as rotated clockwise, decreases the detectors response to metals discovered. Poor conductors such as foil, nickel, and pulltabs are eliminated from detection much lower on the scale than good conductors like coins and most jewelry. Poor conductors can be effectively eliminated from detection, however some response may be heard if these items are near the searchcoil during your search. Jewelry is generally located in the middle of the conductive range so it is important to use no more trash elimination than necessary. Most successful detectorists accept all targets of the conductivity of a US nickel or better. Trash items can always be discarded when the hunt is over.

The Standard Trash Elimination mode permits a very slow scan speed that makes it particularly effective for pinpointing targets. This mode also provides the deepest possible detection depth and is most useful in areas with little trash.

Discrete Trash Elimination:

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.
