recharging of either batteries.

than the standard single earphone that come with the Diver Mag 1.
LAND EARPHONES - For land operation, dual land stereo earphones are available.

MAP INSTRUCTIONS:
The purpose of the world map is to inform you of the normal gamma reading in your area. This information is
necessary for tuning the Fish so it will operate in your area. The map shows the strength of the earth’s magnetic field
in your area listed in gammas. These are the numbers you can expect to be displayed in the readout when operating
the mag in the G1 position. If your immediate area is located between the purple lines, then your frequency will be
less or more than the number on the line. The map gamma numbers are approximate, however the actual readout
should be in the area.
Once you have established what the gamma reading should be in your area the Diver Mag 1 amplifier is tuned for
that gamma reading (tuning will be covered later.
