Oxygen sensors for rebreathers have been hard to come by this year. These are the same sensors used in ventilators. Suppliers prioritise the health of patients with covid-19 during the pandemic. Off course.
After a long wait, my local dealer got a small batch this week, including mine. Warm, moist breathing gas secured for the winter. My favourite season.
In general, Gradient Technical Diving fix pretty much anything I need for diving. Thank you very much!
