Inside RGBM: Deep Stops, KISS Rebreathers. he Physics Behind Tech Diving

n this two-segment episode of Pod Diver Radio, we blend cutting-edge decompression theory with real-world tech diving gear and introduce a new voice to the show. First, we go full decompression geek with physicist Dr. Bruce Wienke of Los Alamos National Laboratory, the mind behind the Reduced Gradient Bubble Model (RGBM). Bruce explains how bubble mechanics changed the way tech divers plan deco, why deep stops became standard in technical training, and how modern dive computers and tables are built from massive datasets instead of "bend 'em and mend 'em" sheep experiments. We wrap with a look inside the KISS Classic and KISS Sport rebreathers from Jetsam Technologies. Electronics guru Dave Dillabough breaks down the KISS philosophy—mechanical constant-flow O₂, diver-driven PO₂ control, triple independent cell displays, integrated bailout, and trimix-capable diluent setups in a travel-friendly package. If you care about RGBM, deep stops, and robust closed-circuit design, this episode is pure tech diver candy.
