the batteries are checked automatically and audibly. Four or more tones indicate the batteries
are very good, two tones indicate the batteries are adequate. One tone or no tone indicates the
batteries should be replaced.
Battery Replacement:
The batteries are located inside the electronic housing with access at the rear of the housing.
To access the batteries, 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 the correct polarity is observed. Re-install the
battery pack by placing the contact end of the pack in the housing with the contacts down.
Verify that the o-ring is well lubricated and free from debris. Add a little silicone grease or
petroleum jelly if necessary. Re-install the battery cap, hand tightening it until it is flush with the
housing and the two index marks are aligned.
Note:
Always use high quality batteries such as Alkaline or nickel metal hydride in this
detector. And, always remove them from the detector and the battery holder when storing the
detector for long periods.

SEARCHCOILS:
The Sea Hunter Mark ll has two searchcoils available for its use.
The 8” searchcoil, which provides excellent depth and good scanning width, is the most
popular size used for general searching in all areas. This searchcoil should be used for your
primary searching.
The 10 x 14” Elliptical searchcoil offers the ability to cover more area and search at a greater
depth, particularly for larger targets.
Cautions:
1. If the battery compartment becomes flooded, remove the batteries immediately, rinse
the compartment with fresh water and allow it air dry. The electronic compartment is
factory sealed and should never be opened; the see-through “helmet-mask” on the front
panel should remain free and clear from condensation. If the window ever displays
moisture, contact the Garrett factory as soon as possible.
2. Before diving always examine the searchcoil and headphone connectors and the
battery cap. Verify the battery strength by operating the detector for a few moments
prior to field use.
3. Dive with extreme caution. Observe diving practices to lessen the risks of becoming
entangled with the headphone or searchcoil cables. Ensure that the headphone vent
holes are open prior to diving.
4. When using the hip mount configuration while diving, ensure that the belt will not
interfere with equipment removal in the event of an emergency.
