The SeaSPY magnetometer product eliminates many of the inherent problems associated with other marine magnetometers such as orientation restrictions, sensor realignment, time and temperature drift, and poor absolute accuracy.

The SeaSPY Towfish
includes:
High sensitivity omnidirectional Overhauser sensor
Electronics module containing all of the driving electronics, including the Larmour counter
Depth sensor
Leak detector
4 lead weights
Custom foam lined shipping case
SeaLINK Software for windows
Also, you can drive up to 10,000m of cable with the SeaSPY Smart Transceiver.
An enhanced version of the communication transceiver, the Smart Transceiver’s adaptive design adjusts to suit a broad range of cable parameters, enabling it to drive up to 10,000m of cable.
Additional advantages include:
Boosts and regulates the towfish supply voltage, to minimize voltage drop over long cables.
Digital auto-tuning of transmission/reception frequencies.
Diagnostic features include digital voltage and current monitoring.
Keeps
time after power off, and automatically sets the towfish time when needed.
Dimensions: 12 x 6.5 x 8 cm (4.7 x 2.5 x 3 inches)
Weight: 300g (0.66 lbs)
Deep Tow Options
1000m SeaSPY towfish tested to 1,500psi
3000m SeaSPY towfish tested to 4,500psi
6000m SeaSPY towfish tested to 9,000psi
Side Scan Sonar Integrations
SeaSPY is compatible with a variety of industry standard Side Scan Sonar systems. The integration maintains the basic system integrity of the SeaSPY towfish and the Side Scan Sonar towfish. Each system can be run independently as well as together.
Altimeter
An integrated, nonmagnetic 200kHz altimeter is available for all depth options. The altimeter provides an accurate and precise (to 0.1m) towfish altitude measurement with every magnetometer reading.
SeaLINK Analogue Output
This enables SeaLINK to generate two user programmable analogue signals for output to any analogue chart recorder.
This option includes analogue output hardware for a PC, and the customer can select between a PCMCIA card, or an ISA-bus card.
Communication Transceiver
The Communication Transceiver provides the complete interface between the data recording PC and the SeaSPY towfish. One side connects to a PC serial port using an RS-232 cable, and the other plugs into one end of the deck leader cable, which in turn connects to the tow cable and towfish.
In addition to conditioning the towfish power supply, the transceiver functions like a modem, providing two-way communication along the same conductors that provide power to the SeaSPY towfish.
Dimensions: 11 x 6 x 3 cm (4 x 2 x 1 inches)
Weight: 130g (0.28 lbs)
30m Deck Cable
Tow Cable
The SeaSPY tow cable is incredibly tough yet light in weight. The cable consists of one twisted pair of conductors, a Vectran strength member that is specifically woven to prevent rotational preference, water blocking and a yellow polyurethane jacket.
