OSTC 4 optical port use
Posted: 26 Dec 2021, 11:10
				
				Hi, 
I have the OSTC 4 with optical port and I get some questions about the port. I only do REC dives.
I know "nothing" about rebreathers so how would I use the optical port with rebreather? Does the optical port have some type specification or number?
Thanks
