The Fenzy ABLJ provided a proof of concept for buoyancy compensation, however the large-volume ring behind the diver's neck caused the jacket to ride up against the diver's throat, [citation needed] despite the crotch strap. In 1968, dive shop owners Joe Schuch and Jack Schammel developed a more comfortable buoyancy compensator vest that ...
The Multi-Band 6 is a radio control technology first introduced on the GW9200 Riseman in 2008 [60] and is a successor to the Multi-Band 5 (which supported synchronisation with five atomic time transmitters around the world) and Wave Ceptor (which supported synchronisation with atomic time transmitters present in the United States and Japan only ...
