Hand Held
Metal Detectors:
JW Fishers Pulse 6X and Pulse 8X are commercial grade
underwater metal detectors that will locate all metals ferrous
and nonferrous. The Diver
Mag1 hand held magnetometer locates ferrous metals (iron/steel),
and detects them from much greater distances than metal
detectors. Fishers PT-1 Pipe Tracker is a special
magnetometer specifically designed to locate, pinpoint, and
track iron and steel pipelines and steel armored cables. The PT-1 will also locate
any iron/steel target. All detectors work equally well on land and underwater.

Boat
Towed Metal Detectors:
JW Fishers Pulse 10 and Pulse 12 metal detectors
will locate ferrous and nonferrous targets. These
boat-towed detectors have a greater detection range and larger
detection envelope than the hand-held models. The Proton 4 magnetometer
is a super-sensitive detector of ferrous
metals (iron and steel). Many major shipwreck finds have
been made using the magnetometer, including Spanish galleons.

Cable
Tracker:
JW
Fishers CT-1 cable tracking system was specifically designed
to locate and track buried power and
communications cables. The CT-1 can locate cables buried on land
and underwater. The primary advantage of the cable tracker is
that it will detect cables much deeper than a metal detector. The
CT-1 will not only locate and track cables,
but also identify fault or
break points exposed to water.

Remote
Operated Vehicle (ROV):
JW Fishers ROVs are completely mobile underwater camera systems
that are controlled from the surface and capable of staying
submerged indefinitely. These ROVs are ideally suited to a
variety of applications including pipeline inspections, river
and ocean searches, dam surveys, oil and gas platform work, fish
farming, and homeland security operations. They can
dramatically reduce search time, as well as the risk and high
cost associated with diving operations. Equipped with the
RMD-1 remote metal detector the ROV becomes a high tech search
system capable of locating weapons, unexploded ordnance,
pipelines, buried treasure, and other metal objects. More

Remote
Metal Detector:
The RMD-1 is a high performance Pulse
induction metal detector that can be attached to any towed underwater
system or ROV. The remote metal detector's unique design makes
it immune to the electrical noise generated by an ROV. The
RMD-1
detects both ferrous and non-ferrous
metal objects on and under the ocean floor while ignoring
minerals in the seabed.

Underwater
Camera Systems:
JW Fishers offers
a complete line of underwater video systems including a
mini-cameras for helmet mounting, diver-held cameras, drop down
cameras to view the bottom, towed cameras, and two Remote
Operated Video (ROV) systems . Each system has an
umbilical to the
surface that feeds live video topside for viewing and recording.

Sonar
Systems:
JW
Fishers manufactures both side scan sonar systems and scanning
sonar. The side scan is a towed system that allows large areas to be searched
quickly. This sonar is one of the most popular wreck
hunting tools because the image it produces looks as if the
water has been removed. What the operator sees is an
unobstructed view of the bottom and any objects lying there.
Side scan sonar is responsible for many major wreck finds. Scanning sonar is
ideal for searching smaller areas. The scanning sonar transducer
can be lowered from a boat or attached to an ROV. A high
resolution image of the bottom up to 40 meters from the sonar
head is produced on a laptop or desktop PC. JW Fishers also
manufactures an underwater altimeter. This specialized sonar
system attaches to any towed equipment and shows the distance
between the towed device and the bottom.

Pingers
and Pinger Receiver:
JW
Fishers has added acoustic pingers and a pinger receiver to their
extensive line of underwater search equipment.
Pingers can be attached to, or
dropped on, any underwater site allowing it to be quickly and
easily relocated.
Fishers Pinger Receiver is gun-like instrument that
detects the acoustic signal transmitted by the pinger.
The receiver can be carried by a diver or deployed from a
boat. Pingers are available in 3 housing sizes; the
standard housing, the Extended Operation Housing, and the Very
Long Duration Housing. The larger housings dramatically
increase operating time.

Transponders
and Interrogator:
Transponders are smart pingers. When deployed, acoustic
sonar
transponders sit quietly until they receive a coded signal
from the acoustic interrogator, they then respond back to the
interrogator. The acoustic sonar interrogator displays the
distance and heading to the acoustic transponder. Many
transponders can be deployed in the same general area (set
at different frequencies) without interfering with each other. Transponders
can be attached to, or dropped on, any underwater site allowing
quick and easy relocation. The
interrogator can be carried by a diver or deployed from a
boat. Acoustic sonar transponders are available in 3 housing sizes; the
standard housing, the Extended Operation Housing, and the Very
Long Duration Housing. The larger housings dramatically
increase operating time.

Accessories:
JW Fishers offers
many accessories to make you're underwater search operation
faster and easier. The
Deep Dive Wing allows for deeper towing without the use of long
lengths of tow cable. The CMS-1,2 are Cable
Management Systems that are used for cable storage and
deployment. The DHL-1 and SL-1 underwater light
systems are surface powered to provide unlimited operating time
for commercial underwater salvage and inspection operations.
