* Steven Libert, president of the Great Lakes Exploration Group, announced
he has located what is believed to be the remains of Le Griffon, the
first European ship to have sailed the upper Great Lakes. The 45 ton barque
carrying 7 cannons was built by the legendary French explorer Rene-Robert
Cavalier, Sieur de La Salle who was attempting to establish a **Northwest
Passage** through **Canada**. **La Salle** wanted to provide a faster way
to connect **France** with its trading partners in the **Far East** and Le
Griffon was to be a vital link in the route between Niagra and **Illinois**.
On its maiden voyage the ship sailed through unchartered waters across **Lake
Erie**, **Lake Huron**, and **Lake Michigan**. On its return trip Le
Griffon and her crew of six disappeared. Libert has spent the last 30
years researching historical records and conducting exploratory dives in
upper **Lake Michigan**. On one of his these dives last summer Libert and
his group discovered an area with a large hand-hewn wood timber protruding
from the bottom. It is thought to be the vessel’s bowsprit and carbon
dating tests done on a sample by Beta Analytic Laboratories in Miami and
the University of Arizona are promising, but not conclusive. To confirm the
exact identity of the vessel requires locating more items from the site,
but with much of the ship entombed in the lake bottom, some high tech
equipment is needed. Key artifacts to find would be one or more of the
seven cannons. To effectively search the football field size area, Libert
has acquired JW Fishers PT-1 pinpointing magnetometer. A powerful detector
of ferrous metal, the PT-1 can easily locate individual ferrous artifacts
even on a wreck site littered with many iron objects. To protect the
scientific and historic value of this incredible find, a partnership has
been established with the state of **Michigan** and the **Republic** of *
*France**. Work is continuing as weather permits.*
* Another explorer utilizing the magnetometer is professor and maritime
archaeologist Greg Cook at the **University** of **West Florida** in *
*Pensacola**. “The thrill of discovery is what I love about archaeology”
says Cook. “When you pick up an artifact that is more than a century old,
its like travelling through time”. The professor works with the
university’s Archaeology Institute, which is both an educational and
research facility. Part of their mission is the examination of historic and
prehistoric sites, both on land and underwater. In addition to a
professional staff of nine archaeologists, the institute has artifact
conservation labs, exhibit space, and lots of special equipment including
remote sensors for the marine environment. One of these devices is Fishers
Diver Mag 1 hand-held magnetometer which can locate a large wreck at more
than a quarter mile away. Another device is Fishers Pulse 8X underwater
metal detector which helps in locating the nonferrous metal artifacts.*
* The southeast Asian country of the **Philippines** is made up of more
than 7,000 islands. Over the centuries explorers from around world have
traded with it’s inhabitants, and over the years thousands of ships have
crashed on its reefs, sunk in typhoons and been plundered in wars. The area
is a veritable graveyard of historic wrecks which caught the attention
Captain Steve Morgan, who was fascinated by the tales of these lost ships
and their valuable cargoes of porcelain, jewels, and riches. In the 1990’s
Morgan formed a company, Black Coach Management, and began to acquire the
men and equipment needed to find these historic time capsules. Three of the
pieces the group picked up was JW Fishers SeaOtter ROV, a remote operated
vehicle with high resolution video camera capable of descending to depths
of 500 feet, a Diver Mag 1 magnetometer, and the Pulse 8X metal detector.
One of the first wrecks the Black Coach team began to hunt was a Spanish
Galleon that had sailed from the province of Palawan in the late 1700s
carrying three large bronze bells for the newly constructed catholic
missions in California. The ship was attacked and sunk by pirates and for
more than 200 years lay hidden on the bottom of the **South China Sea**.
The remains were discovered by local divers who came upon what the
described as “a reef on the bottom that is not really a reef”. That “reef”
proved to be the ship’s cargo arranged in a pile 60 feet long, 10 feet
high, and more than 25 feet wide. Morgan and his team, working with
Philippine archaeologists, used the ROV to survey the wreck lying at a
depth of 170 feet. Divers were then sent down with the metal detector and
magnetometer and recovered hundreds of artifacts from the site. *
* A few of the many other explorers and archaeologists using Fishers
detectors are Dr. Bridget Buxton with Univ. of Rhode Island, Dr. Charles
Beeker at Indiana Univ., Clive Cussler’s NUMA, Mel Fishers’ Salvors Inc,
Cultural Resources Dept. Biscayne Ntl. Park in Florida, Odyssey Marine
Exploration, North Carolina’ Dept. of Cultural Resources, Woods Hole
Oceanographic Institute, Max-Planck Institute in Germany, and Sea Heritage
Panama.*

JW Fishers PT-1 pinpointing magnetometer

*The PT-1 pinpointing magnetometer is the ideal tool for iron pipelines
and steel armored cables. The PT-1 has both audio and visual readouts.
Included in the kit are land and underwater earphones, along with AC & DC
battery chargers. The rechargeable batteries power the PT-1 for 15
continuous hours. Hard carry case is optional.*
* The PT-1 not only tracks pipes and cables, it will also locate anchors,
chains, dredge heads, weapons, explosive devices and any other ferrous
metal object within its detection range. To request a technical data sheet
on the PT-1 or any of Fishers underwater search systems email to *
*info at jwfishers.com* <info at jwfishers.com>* or go to www.jwfishers.com

JW Fishers Diver Mag-1 magnetometer
* This hand-held magnetometer is a super sensitive detector of ferrous
metal (iron/steel) that works equally well on land and underwater. With a
one gamma sensitivity this microprocessor driven marine magnetometer can
detect pipelines, cables, wreck sites, anchors, moorings, tools, weapons,
and just about any ferrous metal object of any size. Ruggedly constructed
for commercial operations, the Diver Mag was designed with user friendly
controls for ease of operation. A five digit LED display and underwater
earphone alert the operator to the presence of a metal target. The large
LED display is easy to see even in dark or murky water. An internal 12 volt
rechargeable battery powers the system for two continuous hours. An
external battery pack is also available which doubles the operating time.
The Diver Mag's adjustable buoyancy allows the operator to make it
neutrally buoyant in salt or fresh water. For more information request a
technical data sheet at www.jwfishers.com <http://www.jwfishers.com>.
