SDM-4000 Digital Magnetometer
Robust, User Friendly and Economical |
| |
The SDM-4000 was specifically designed for
anomaly detections and makes the perfect economical tool for locating
ferrous metal objects, that lay on the bottom or are buried. It is
depth rated for 4000 ft. and can be used with cable lengths up to 4000 ft.
Using the forward motion of the boat, the depressor wing keeps the tow fish
down. This saves on the amount of cable necessary to reach depth.
The SDM-4000 magnetometer is specially designed for finding items having
ferrous content. Even old wooden shipwrecks can be detected from 200
feet away because of their steel pins and bolts. This magnetometer is
not built like other expensive models that have glass components that break
easily. The SDM-4000 is digital and is very robust, easy to use and
economical. It is ideal for shipwreck hunting.

Accessories for the SDM-4000 Magnetometer:
 |
Cable Towing Clamp
This simple but
effective clamp provides a means to quickly adjust
the cable tow length and then hold the cable
securely. The specially designed jaw holds the
cable tight but is gentle to the jacket. A must
for any towing application. Accepts cables up to
1/2 inch (12mm), larger models possible. |

 |
Layback and Offset Calculator
This inexpensive, easy
to use software simplifies the calculation of
target position. This small always on top window
allows you to calculate the exact geodetic
location from side-scan and other surveys by
simply entering in the boat position, heading,
layback and offset. Not only does it perform the
calculations in a flash, it allows you to save
your targets, with comments to a file importable
by other software including GIS and navigation.
Anyone doing survey operations cannot afford to be
without this inexpensive time saver. |

Connects easily to
your NoteBooks USB port, the unit receives power
through the USB connector, eliminating extra
cables.
