TO THE OWNER The Garrett Sea Hunter Mark II has an unparalleled reputation among treasure hunters, law enforcement agencies and various industries as one of the most reliable and sophisticated submersible metal detectors of its kind.
exclusive Discrete T arget Elimination mode. The custom designed double- o-ring sealed housing is durable and lightweight, with individual, o-ring sealed battery and electronics compartments that makes battery replacement hassle free.
CONTROL FUNCTIONS Power - Use to turn the detector on and choose either of two search modes. A battery check occurs automatically each time the power is switched on. (Figure 1) Threshold - Use to set the base audio level according to an individual's hearing ability and how loud the outside noise is.
Elimination - Use in conjunction with either the Standard or Discrete T rash Elimination modes to choose the elimination level appropriate to your search needs. As the elimination knob is rotated clockwise, an increasing number of undesirable items are excluded from detection.
SEARCH MODES Standard Trash Elimination and Discrete T rash Elimination are the search modes available with the Sea Hunter Mark II . The selector switch for these modes is located on the right side of the panel. Standard T rash Elimination is the search mode normally available on conventional pulse induction (PI) metal detectors.
the response to good conductors such as coins and fine jewelry . In Standard mode, the response to poor conductors can be eliminated effectively; however , if these objects are too close to the searchcoil, a detection response may occur . The response to good conductors, although somewhat diminished, remains relatively strong.
target discrimination. The background audio threshold remains at the chosen level until the searchcoil passes over targets in the knob's "accept" range, at which time a sharp audio response, a characteristic of all motion detectors, occurs.
(Standard Mode with elimination at 0) metals can be detecte d at 10 0% capability . As the elimination control is increased in either search mode, the response to various targets decreases. Note that the response to many metals decreases more rapidly in Standard mode than in Discrete mode.
T o pinpoint in Discrete mode, you simply sweep the searchcoil from to side to side over a target. The searchcoil must remain in motion to produce a detection response. This mode is designed to provide superior pulse induction target discrimination and is extremely effective in areas with lots of trash.
ASSEMBL Y 1. Choose a desired operating / stem / control housing configuration. Assemble the stem and attach the control housing as desired. (Figure 3,4,5).
Figure 5, Long stem with hip mount configurations 14.
2. Attach the searchcoil to the lower stem. Align the mounting holes of the searchcoil and stem, insert the threaded bolt through the holes and hand-tighten the knobs; Do Not use tools. (Figure 6) 3. Wrap the cable around the stem and secure it according to your operating configuration.
4. Ensure the searchcoil connector at the rear of the control housing is clean and the o-ring is well lubricated; add a little silicon grease or petroleum jelly if necessary . Do not coat connector pins with lubricant. Insert coil connector and gently hand tighten.
OPERA TING PROCEDURE 1. Switch on the detector and note the results of the battery test represented by a range of one to four beeps. Four beeps indicate the batteries are full, one beep indicates they must be replaced. 2. Select the Standard or Discrete T rash Elimination mode.
FIELD RECOMMENDA TIONS Knowing the conditions of your search and which items you want, or don't want, to find will help you choose the search mode and elimination setting which best suits your needs. Depending on your search goals, you may want to set the elimination no higher than necessary so that you can detect most metals.
line (not a wide arc); it helps keep the searchcoil level, reduces the likelihood of lifting the searchcoil at the end of each sweep and ensures the overlap sweeps remain uniform. Finally , it is important to remember that any detection signal, no matter how loud or faint, represents the sound of metal and its source should always be determined.
SEARCH & RECOVER Y TIPS T reasure Hunting Research - The first rule of successful treasure hunting, whether on land or in the sea is to do your homework. Learn as much as you can about the areas you want to search, the kind of treasure you want to find and the best ways to recover it.
wall bases, bridges, channel-dredging sites and sunken vessels. Study surf and weather patterns - Pay attention to storm, wind and tide activity . T reasures from deepwater vaults are often transferred to shallower locations like tidal pools and water-filled depressions near the shoreline.
Use the right recovery tools - Use the right tool for the job and you'll recover treasure in no time. Knowing what you're digging for and the kind of surface you're digging into will help you choose the right digging tool.
materials of unwanted or hazardous metal items. Metal detectors have been used to find a variety of hidden items, such as pipes, scrap metal, nails embedded in lumber , underground electrical power cables and oil barrels.
Land searches - When searching near wire fences, metal buildings, etc., make sure that you scan the searchcoil parallel to the structure. 24.
CAUTIONS 1. T o avoid acid damage you should install high-quality alkaline or nickel metal hydride batteries and always remove them prior to storing the detector . 2. If the battery compartment becomes flooded, remove the batteries immediately , rinse the compartment with fresh water and allow to air dry .
4. Dive with extreme caution. Observe diving practices to lessen the risk of becoming entangled with the headphones or coil cables. Ensure that the headphones' vent holes are open prior to diving. 5. When using the hip mount configuration, ensure that the belt will not interfere with equipment removal in the event of an emergency .
MAINTENANCE 1. Wash off any sand, salt and residue from the detector immediately after each use. 2. Avoid high, internal temperatures by protecting the equipment from the sun. Store equipment in a cool location; avoid storage in a hot vehicle. 3. T ake advantage of Garrett's preventative maintenance program.
BA TTER Y REPLACEMENT T o access the battery pack, unscrew the battery cap at the rear of the detector housing, by hand. Do not use tools. The o-ring should remain in the control housing while the battery pack slides out. When installing batteries ensure that they are aligned with the correct polarity (plus and minus) markings.
jelly , if necessary . Reinstall the battery cap, hand tighten it until it is flush with the housing and the two index marks are aligned as shown (Figure 9).
RECOMMENDED ACCESSORIES Using the right recovery tools is as essential to treasure hunting as the detector itself. Here are a few examples of recovery tools and their uses (Figure 10). A hand scoop is useful for dry sand and shallow water recovery up to two feet.
SPECIFICA TIONS • Circuit type: Pulse Induction, automatic cancellation of salt/iron mineralization. • Frequency: 750 pulses per second • Submersion depth: Up to 200 feet (65 meters) or seven at.
REP AIR SERVICE If you have difficulty operating the Sea Hunter Mark II , take a few minutes to re-read this manual and check the batteries, switches and connectors. If you are unfamiliar with underwater detectors, consult your local Authorized Garrett Dealer or the Garrett factory .
