This TVG does not have the long aluminium "A" Frame of the Geomatrixs system and this aids deployment and recovery from vessels with lower deployment sheaves.

The post Geometrics TVG: G-882 Frame appeared first on Unique Group.

]]> Designed to support the standard G-882, with or without altimeter.

It provides a stable tow platform with G-882 magnetometers on a fixed 1.5 m baseline for optimum detection of a wide range of targets.

The Geometrics frame does not include the large A frame (as per the Geomatrix version). This aids deployment and recovery on smaller vessels without a high sheave where the long A frame of the Geomatrix TVG frame adds to the suspended height.

The tow point offers attachments for the Geometrics telemetry system, or positioning beacons, increasing the operators confidence in determining the layback and position of the TVG frame.
