Edo Western Corp. New Deep Tow Survey System

The new Edo Western 515A- 604 Deep Tow Survey System uses a new hydrodynamically designed tow vehicle to provide efficient operation for deepwater side scan surveys in ocean depths up to 2,000 feet.

The highly successful 515A- 604 tow vehicle combines an extremely stable tow characteristic with a very efficient depressor to achieve maximum tow depth without the aid of additional depressor equipment. The new tow vehicle is designed to operate with Edo Western standard 606 side scan sonar transducers or the complete series of Edo Western 515A Hi- PACT bottom penetration transducers.

The side scan and bottom penetration transducers can be used separately or simultaneously.

The unique capabilities of the 515A-604 system are also made possible by a multiplexed data transmission system. This method of data handling eliminates crosstalk between data channels, plus it permits use of simple cable designs.

The 515A-604 specifications are as follows: 515A TOW VEHICLE: maximum towing speed—12.5 knots; depth rating—500 to 2,000 feet, and weight (including transducer) —450 pounds nominal.

TOW CABLE: constructiondouble armored; diameter—0.46 inches; standard length—100 feet, and fairing—recommended for towing above 6 knots.
