DETECTION AREA
The detection area for our pulse detectors is bowl shaped and is quite
large - much larger than the coil diameter.
The above illustration represents the detection area for a penny, a larger
object would have a larger detection area. Due to the large detection area
of the PULSE 8X, a variable sensitivity switch is provided. This enables
the sensitivity to be decreased, once a target is detected, to allow easy
pinpointing of the target.
Different size coils will effect the detection distance. The larger the coil
the deeper the ground penetration for larger objects; but the larger coils
will not detect small (coins, rings) targets as well as small coils.
If you purchased the underwater connector option you can easily change
coils in the field.

OPTIONAL SPARE BATTERY PACK
The spare battery pack is identical to the battery pack that comes with the
PULSE 8X. The Pulse 8X battery pack is made up of seven sub-C 1.2
volt NiCad batteries.
Charging Spare Battery Pack
If you use a spare battery pack it must be charged 12-14 hours by install-
ing it in the detector (see below).
Removing the electronics for changing batteries
- Remove the six 6-32 x 5/8" stainless screws from the front face-
plate.
- Pull the electronics straight out.
- Unplug the battery cable from the board and plug in the new bat-
tery (OK to reverse the plug around).
- Clean the o-ring and o-ring seat on the housing.
- Lubricate the o-ring with a silicone based grease (wiping off any
excess oil)
- Position the battery under the electronics.
- Place the o-ring around the small faceplate (sm. faceplate is the
small yellow faceplate behind the large clear faceplate). Carefully
insert the battery and electronics into the housing.
- Holding the housing opening straight up, use two (2) playing cards
to push the o-ring into the seat while applying a slight pressure
against the faceplate.
- Tighten the six 6-32 x 5/8" screws into the faceplate while still
applying pressure so the o-ring will remain in place.
NOTE 1: Never use glue or any adhesive to hold the o-ring in place
as this may allow water to enter the housing.
