The Seamap Integrated Tailbuoy consists of a fiberglass hull to provide floatation, a towing bridle to attach to the tow cable, a waterproof connector to connect to a source of power and telemetry wires, a BuoyLink GPS receiver, a marine rechargeable battery and a navigation hazard strobe light. All electrical components are wired to a waterproof stainless steel junction box housing cable interface and battery charging circuitry.

The Tailbuoy is attached to the tail of the streamer and towed from the front by means of a towing bridle which is attached on either side, with shackles supplied.

The Tailbuoy electrical system is connected to the streamer using a single connector which routes power and telemetry lines to the stainless steel enclosure.

The stainless steel enclosure houses the modem card which provides data telemetry functions, battery charging capabilities and supplies power to the BuoyLink GPS unit as well as the flashing beacon.

The Flashing Marker Beacon is a marine type Jotron Marker Beacon mounted on the starboard side antenna frame mast and connected to the modem enclosure that provides power using a waterproof cable.

Benefits of totally encapsulating high capacity batteries involve complete protection against water intrusion, as well as greatly reduced risk of explosive gas build up by the exclusion of airspace.

Battery venting is facilitated by proprietary ventilation system through the base of the encapsulant. The batteries are internally fused for increased safety in case of inadvertent short circuit.
