GROUND SEARCHING MD-5008
Ground Searching Metal Detector.
Penetration Depth 3~ 3.5 meters.
MD-5008 metal detectors, 3-3.5m depth of detection, adopt advanced technique and attach high quality components which have features of ground balance, good discrimination ability, wide detection range, accurate orientation, strong resolution and easy operation
The metal detectors are mainly used to detect and identify underground metals. Besides military using, they are widely used in:
( 1) Security inspection, public security organs’ ransack:
( 2) Scan metal foreign matter in raw, fuel and foods;
( 3) Scan metal articles in mail or luggage;
( 4) Detect underground pipelines, cables;
( 5) Archeology, mineral exploration, find underground metal articles.
( 1) Attach external battery box and bag
( 2) Attach big and small search coils
( 1) Emission Frequency: 6.99KHz
( 2) Signal Frequency: 437Hz
( 3) Weight: 2.87KG
( 4) Sensitivity: Small coil: 25~ 30cm ( test 25US cent)
Big coil: 35~ 40cm ( test 25US cent)
( 5) Max Detection: Small coil: 1.5 meters
Big coil: 3.0~ 3.5 meters
This conclusion is elicited by testing a aluminium sheet ( 60cm* 60cm* 1cm) buried in dry soil.
( 6) Power Supply: 8pcs 1.5V Batteries
( 7) Operation Mode: Ground balance mode; Discrimination mode.
Finds buried or paved-over valves, boxes, vaults, survey markers,
water or gas meters, conduit, or other metal objects

M-97 Metal Detector
By Fisher Research
Designed for finding buried or paved-over valves, boxes,
manhole covers, or any other concealed metallic object.
The Fisher M-97 is specially designed for finding buried or paved over valves, boxes, or manhole covers, or any other concealed metallic object. It also locates targets made of aluminum, brass and lead.
The M-97 features pushbutton tuning, allowing the user to quickly and easily maintain optimum sensitivity for easy pinpointing of buried metallic objects. Plus, the M-97 offers auto-tune circuitry and a waterproof search coil.
New to the M series is the ease with which the M-97 can be stored. Just compact the lower stem, twist the search coil 90 degrees, and fold the search coil flat. The M-97 fits easily into the optional carrying case.
In the Fisher tradition, the M-97 is affordable, tough, and simple to use while providing maximum performance. A two-year limited warranty comes standard with the unit.
