Salinity Balance
(This Process is similar to the manual ground balance)
1. Ground Balance the metal detector on the dry side of the beach with Salt Mode activated.
(If the beach is not mineralized, like white sand beaches, ground balance is not necessary and manually
set the ground balance to 500.)
2. Activate the Salt Mode adjustment (cursor
highlights “
St/Salt
” icon (Fig.4))
.
2. If the salinity is unknown, set the salinity level to 28.
4. Choose a place in the water that is between a foot to a foot and a half deep.
(BE CAUTIOUS OF TIDES, CURRENTS, SINK HOLES, ETC… WHEN DOING STEP 4. YOUR SAFETY SHOULD
ALWAYS COME FIRST)
5. Move the search coil up and down starting from 1 inch above the water level, up to approximately 6
to 8 inches, while keeping the search coil parallel to the water level and adjusting the salinity level,
increasing or decreasing. Find the salinity setting with which minimum or no sound is produced when
moving the coil up or down (
The salinity level can be adjusted only if the”St/Salt” icon is highlighted)
.
(THE METAL DETECTOR IS LESS SENSITIVE TO THE SALINITY ON THE LOWEST FREQUNECY-THE HIGHER
THE FREQUENCY, THE MORE SENSITIVE THE DETECTOR BECOMES TO THE SAILINITY AND LOW
CONDUCTIVITY TARGETS)
(IF A HIGHER SENSITIVITY IS DESIRABLE, SMALL SALINITY IMBALANCE CAN BE TOLERATED-THE
DETECTOR WILL BE NOISIER)
