Chapter 5 Surf Dual Field Information
Proper Care
Cleaning
The entire Surfmaster Dual Field is waterproof and
submergible. It can be cleaned with fresh water
and a mild soap. After cleaning, dry the instrument
thoroughly.
Weather Conditions
Protect your detector from excessively cold weath-
er. Freezing can damage the electronic components,
the case and/or the battery. Excessive heat can also
damage the instrument. Never leave it in the sun.
It's best to lay it in the shade when not in use. If it's
left in a car or boat on a hot day, cover it to protect
it from the direct rays of the sun, and then leave the
windows slightly open to permit ventilation.
Saltwater
Saltwater is very corrosive! After your detector has
been exposed to saltwater, rinse the loop and rods
in fresh water. Then wipe it with a cloth dampened
with fresh water, and dry it thoroughly.
Storage
If you plan to store your instrument for any length
of time, unsnap the batteries and remove from the
instrument. Whenever your instrument is not in
use, turn the ON/OFF GAIN Knob all the way to
the left until it clicks off.
Travel
If traveling and expecting large variations in alti-
tude, such as traveling through mountain passes,
disengage control box latches to allow equalization
of pressure.
Information
Opening Control Box
When opening the control box, first make sure the
instrument is dry. Water, if allowed to contact the
circuit board, will damage it.
When opening the control box to replace the bat-
teries, always make sure the “O” ring is free of dirt
or sand, and is properly positioned before the case
is closed. If this “O” ring shows any signs of wear,
replace it before using this instrument in the wa-
ter. This "O” ring, Whiteʼs Part Number 527-0040
is a custom shape, and can be ordered from your
White's Dealer or Service Center. Failure to main-
tain the “O” ring properly will result in extensive
damage to the instrument, and will not be covered
under warranty. If traveling abroad or using this
model extensively, ordering additional “O" rings is
highly advisable. Professionals typically replace the
“O” ring once a year.
