Cochran Tethered Diving Telemetry Lifeguard Hoseless, Wireless, Gas Integrated System The Lifeguard System consists of two parts: a Cylinder mounted CPU Unit and at least one peripheral. The CPU Unit typically has a powerful processor, sophisticated firmware, numerous sensors, and an omnidirectional data transmitter. It is powered by two redundant, user- replaceable batteries with a typical life in excess of one year. The peripheral Units typically have a powerful processor, sophisticated firmware, a Display, and an omnidirectional data receiver. It is powered by a single, user- replaceable battery with a typical life in excess of one year. ALL dive data measured and computed by the CPU Unit are burst-transmitted once per second over a proprietary link to the receiver in any peripheral within range that has the proper ID number.
