Hi Kent, Sorry for the (VERY) late reply - My exuse is that I don't use RBW a lot and apparently it doesn't send me notifications about incoming private messages like yours. Back to your question: I use an original ISC Manta Lung pulled as far back as possible to avoid head movement restrictions. So it's a BMCL and unlike most other RB divers I'm very happy with the Manta Lung
Hi, Looking at your profile picture. Are you using TOS counter lungs or just the OTS mounted farther back? If they are TOS, how do you like them (for easy of use ect....) thanks for taking time to read and get back to me. Kent
