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.
SEARCH MODES
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.
