Model TH-2 Towed Omnidirectional Hydrophone

The TH-2 provides a simple method for mobile active tracking: its small size and hydrodynamic shape allows for trolling at speeds up to 5 knots, while the long cable length minimizes the affect of engine and prop noise. Eyelets allow attachment of small weights or diving lures to ensure the hydrophone is kept at depth while trolling. This design, though simple, rivals more elaborate and expensive systems in actual field trials.
