Installing Batteries
The Surfmaster Dual Field is powered by eight AA
Penlight batteries. Alkaline cells are recommended.
Lift the latches on the sides of the case and remove
the lid, using care not to lose or damage the “O”
ring seal, located on the lid. Remove the battery
holder from the parts bag and install the penlight
batteries. Connect the battery lead to the pack and
put the pack into the case. Clean any dirt or sand
from the “O” ring, case and lid. Replace the lid, be-
ing sure it is seated properly. Close the case latches.
Look at the “O” ring to be sure it is compressed
and seated properly on the lower case surface.
NOTE: Improper assembly of the case can cause
it to leak and may damage the detector.
Standard carbon-zinc or heavy duty batteries will
last for approximately 15 hours. Alkaline batter-
ies are recommended and should provide 25 to 35
hours of continuous operation. Battery life will
vary with changes in temperature, number of target
responses, as well as battery type.
Testing Batteries
A battery test can be performed with the T-HOLD
control. When the T-HOLD is turned fully counter-
clockwise until it clicks, the audio battery tester is
turned on. The condition of the batteries is indicat-
ed by the volume of the “beep.” When the batteries
are new a loud “beep” is heard. The “beep” will be-
come weak when the batteries need to be replaced.
