FOR DIVING

Unlike induction-balance metal detectors, the IMPULSE ignores

the disruptive influences of salt water and black sand. This

capability, along with its deep-seeking sensitivity to iron, makes

it ideal for underwater treasure hunting and wreck diving. The

IMPULSE is also waterproof to a depth of 250 feet. Remember,

always practice safe diving methods.

Caution: Hipmounting the IMPULSE control housing is not

recommended for underwater use. The search coil cable may

become entangled with a submerged object, making it difficult

for the diver to resurface quickly in case of emergency.

1. Adjust the stem length as short as you can without

having the search coil detect your diving gear.

2. Adjust the search coil parallel to the seabed,

river or lake bottom.

3. Make sure extra cable is coiled tightly on the upper

stem as closely as possible to the control housing, with

just enough slack near the search coil to allow it to

swivel as far as it can in either direction. Extra cable

near the search coil may generate false signals.

4. Remove the tethered earphone plugs for rapid

pressure equalization as you dive and return to the

surface.

Shortened stem length

Extra cable

When diving with your

IMPULSE, use the shortest

possible stem length, with

the extra cable wrapped

tightly around the stem, as

close as possible to the

control housing.
