LPS-1 Handheld Sonar Instructions

Unit Operation

Hold the unit in your hand as you would a flashlight and simply slide the
switch forward. By doing this, the night light for the digital display will
come on and three horizontal bars will appear in the display. This
means the unit is on and searching for a reading.

Place the transducer end of the
unit in the water, make sure
you are pointing strait towards
your target. For example,
strait down towards the
bottom. The LPS-1 will
continue to monitor the depth
as long as the switch is held in
the forward position. When
the switch is released the

depth reading will stay locked
on the display, for about 10 seconds, then it will automatically shut itself
off. Remember to release the switch before you lift the unit up to be
read.

Failure to hold the transducer end of the LPS-1 straight or perpendicular
to the target will result in distance or depth reading slightly longer or
deeper than it really is. Also, taking readings in or over weeds or
schools of fish can result in incorrect or erratic readings.

Installing the Battery

The Model LPS-1 requires one 9 Volt Alkaline transistor battery. It goes
in the end cap that is next to where the strap is attached to the body
assembly. To install a battery this end cap must be unthreaded and
removed. Slide the battery into the body cavity then attach the battery
snap to the battery. It will only fit one way, so if it doesn't fit on easy
you may have to reverse the battery. Replace the cap and screw it
down into the unit. Tighten firmly, making sure the O-ring is not out of
place. If the battery becomes weak, the displays backlight will begin to
flash.

The end cap which is closest to the Digital Read out is the transducer
end. This end of the LPS-1 doesn't ever need to be taken off, however
occasionally it should be tested for tightness, to make certain that it is
waterproof.

Applications

Portable Uses - Turn unit on and touch the transducer end into water,

perpendicular to the bottom. Hold the switch forward until the unit locks
onto a reading. Release the switch and then raise the unit to read the
depth. If additional readings are desired - repeat procedure.

Scuba Diving - For your safety make certain that the LPS-1 is
operating correctly by testing in shallow water. For deeper diving
tighten snugly each end cap against its rubber seal. Watch the rubber
seals to make certain there are no bubbles escaping around the seals.
If a small stream of bubbles appear, tighten that particular end cap
more or until the stream of bubbles quit.

Ice Fishing - The LPS-1 will read through ice as long as it is fairly clear
and free from air bubbles, white ice. Clear away the snow and look for
clear hard ice then set the transducer end of the LPS-1 onto the ice.
Push the switch forward and, using some water, pour a small amount
directly onto the area where the LPS-1 contacts the ice. Hold the switch
forward until the unit locks onto a reading. If the conditions are not
right you may need to use more water and several readings should
taken to verify the proper depth. Note- Cold is very hard on batteries.
Make sure you keep the LPS-1 warm so when you need it, it will be
ready.
