One other RB80 diver - but luckily I know him
The RB80 is designed to be easily able to mix and match with GUE open circuit teams. Al and I will dive together building experience at first but there is no reason why if gas plans allow we cannot dive with GUE OC divers as I did when I did the Ressl dive in June last year when I dived OC with two RB divers.
