BOAT TOWED
J. W. Fisher's manufactures
a line of boat towed metal detectors. They range from the
very economical boat deployed
Pulse 7 to the very sophisticated boat towed Proton 3
magnetometer. The Pulse
induction metal detectors detect all metals over short
ranges. The Proton 3 magnetometer
detects only ferrous metals (iron/steel), but at
long ranges.
Proton 3
A professional marine magnetometer for
ferrous metals. Extreme
sensitivity, detects
ferrous (iron/steel) metals. Easy to tow even at high speed.
Ideal for any size
search area. Backlit LCD display for night operations. Options
include: printer for
printing mag readout and Loran/GPS position coordinates;
and RS232 output for
input to a computer system. Software to store and display
mag readouts and GPS
positions also available. Almost every major old wreck
found over the past
40 years has been located with a Proton mag including Mel
Fisher's "ATOCHA".
The Proton 3 has been purchased by Army Corp of
Engineers, commercial
salvage companies, and treasure hunters worldwide.
Operates on 12 vdc.
Proton 4
J. W. Fishers Proton 4 Mag
Proton 4 - Fishers most powerful metal detection system
The most powerful boat towed metal detector for ferrous metals.
A high performance, micro-processor driven
system, the Proton 4 is the ultimate
detector for ferrous metals such as iron
and steel. The Proton 4 is in use by military,
law enforcement, commercial, and salvage
divers world wide. It's extremely large
detection area make this detector ideal
for both commercial operations and
professional treasure hunters.
The claim-to-fame of this marine magnetometer
is it's rugged construction, ease of
operation and the number of available
options. The Proton 4 has one gamma
sensitivity, the maximum practical sensitivity
for a towed magnetometer. It's
maximum range capability of 1500 feet
on each side (3000 feet total swath for a very
large target) let's you cover a wide area
quickly and completely. The detection range
is unaffected by the medium between the
metal detector and the metal target.
Performance does not change whether detecting
through air, water, silt, sand, or
solid coral.
The Proton 4 system includes tow fish with 150 feet of
cable, and a top-side control unit. The control unit
features easy to read LCD display, audio alarm, and
variable sensitivity switch (for pinpointing targets).
An optional built-in printer is available which gives
hard copy of mag readouts and Loran or GPS
position. Options include 300 foot tow cable, UA-2
altimeter, RS232 data output, data collection and
storage software, 500 and 1000' depth rated versions.
The system is powered by a 12 volt battery with a
total power consumption of only 40 watts.
Key Features of the Proton 4:
Commercial grade construction, one gamma
sensitivity, extremely large detection
area, faster towing speeds than Pulse
systems, and ability to make permanent record
of readings.
The Proton 4 is backed by Fishers exclusive,
unconditional TWO YEAR warranty.

HAND HELD
Here is a list of J. W. Fisher's
Mfg. Inc. line of Hand Held Metal Detectors.
Pulse
8X
Top of the line hand held metal detector
for land or water use. Top of
the line, the Pros
choice, most sensitive pulse detector available on the market
today. Easily out performs
them all. Comes with a complete accessory package
which includes everything
needed for land and underwater detecting. Used by
police, military, and
commercial divers around the world. Internationally famous
treasure hunters Mel
Fisher and Carl Fismer have purchased a quantity of these
detectors for their
own treasure recovery operations. Rechargeable batteries.
Options includes field
installable coils: 10", 16", 18" with 100' cable, 8" by 48"
oval with skids and
100' cable, and a 1" diameter by 22" long hand probe. The 18"
and 8" by 48" coils
can be deployed from a boat.
Pulse
6X
Our Most economical hand held detector,
can be upgraded to Pulse 8X.
Best value. Equals
the performance of the competitions top of the line detector.
Land handle, meter
and u/w earphone included. Same high quality construction as
Pulse 8X.

REMOTE OPERATED
J. W. Fishers Pulse RMD-1
RMD-1 - Fishers Remote Metal Detector
A metal detector with high noise immunity that can be remotely operated.
The RMD-1 is a high performance Pulse induction
metal detector which can be
attached to almost any ROV or towed underwater
system. Pulse induction technology
allows the RMD-1 to detect both ferrous
and non-ferrous metal objects on or beneath
the ocean floor while ignoring mineralization
in the seabed. The remote metal detector
locates and tracks underwater pipelines,
finds missing tools and dredge parts, locates
weapons and unexploded ordnance, and finds
lost treasure.
The
system employs two coils molded into
rugged ABS shells firmly attached to the
underwater vehicle with a corrosive-proof
tubular PVC frame. The frame provides
a
sturdy mount for the coils and positions
them
out in front of the ROV so as not to be
affected by the ROV's metal parts. The
oval
coils produce a detection envelope which
extends 3 to 5 feet into the bottom. The
sleek,
low profile coil design minimizes drag
and
weight on the ROV.
When the coil senses metal it sends a signal
to the RMD-1 "downstairs electronics
unit" attached to the underwater vehicle.
The downstairs electronics unit processes
the information and can produce RS232
output, 0-5 vdc output, or a proprietary signal
used by the JWF topside control/readout
unit. The output from the downstairs
electronics unit can be transmitted through
the ROV's umbilical or a separate cable.
The ROV can power the downstairs electronics
unit or power can be supplied by the
umbilical cable.
The standard RMD-1 has a topside control
box which displays the readout with both a
meter and audio alarm. The closer the
proximity of the metal target, the stronger the
reading. The topside unit can use the
underwater vehicle's umbilical cable to supply
voltage to the downstairs electronics
unit and to receive the output signal from the
downstairs unit. The RMD-1 can be powered
from 120 vac (standard) or 220 vac, or
9-36 vdc.
Key Features of the RMD-1:
The RMD-1 is easy to operate and readily
attaches to most any underwater vehicle.
Special coil sizes can be supplied.
The RMD-1 is backed by Fishers exclusive,
unconditional TWO YEAR warranty.
