Calibration of rebreather electronics is one of the most critical processes when setting a rebreather to go diving. Always refer to the official rebreather manual provided by the manufacturer, as there are different processes depending on the specific rebreather, but here are some tips to help you get started.
There are several possible root causes for a peripheral unit (Petrel, Nerd, LED HUD) that turns on by itself or cannot be turned off. Following these tips will help isolate the source of the issue so you can get back in the water as quickly as possible.
Rebreathers are complex devices that rely on numerous components to function correctly. When you encounter a problem, it’s valuable to isolate the issue to a specific component before seeking service. The idea is to verify whether a certain issue occurs with different peripherals or different head electronics.
Electronic components in a rebreather are essential for monitoring the partial pressure of oxygen in the breathing loop. Shearwater manufactures a variety of electronic components tailored to meet the diverse needs of rebreather manufacturers. Rebreather divers should understand these three main categories: communication protocols, functions, and connections.
I have been diving and teaching on open circuit scuba for 29 years, so when people see me at the dive site with this box on my back I do get asked all the time why make the switch now? “What took you so long to make the switch?” or “Why bother switching to CCR now?”
Divers who understand the inherent uncertainty in decompression modeling and want to take a more active role in their own dive planning can use available tools to tailor the limits to their needs or preferences. This is a good choice for dynamic conditions or complex dives, when the goal of simply staying away from limits gets hard to track. Gradient factors represent a good tool to actively manage risk.
