Hi, hope this is not a repeat of a frequent question but did not see anything exactly like this. I took a GUE fundamentals course this spring and and have been practicing SMB deployment but I still stink at it. I can't get enough air orally into the SMB at any depth to do a solid deploy. I thought this was my fault but now I wonder if it is the SMB. I have an old SMB that uses the twist lock style valve that must be depressed to inflate. All the air seems to escape out the side of my mouth and very little gets into the SMB when I try to inflate under water. Surface inflation is no problem. My instructor's SMB is a Halcyon with a non twist valve that could be LP inflated but will also orally inflate. Is this type of valve significantly easier to inflate at depth? Anybody have any recommendation on orally inflated SMBs or techniques that may solve my issue? Could also do a semi closed SMB if that is the way to go. LDS owner and instructor would definitively prefer I buy Halcyon since he is a a big fan of them and sells their equipment. I would like to become a technical diver before I am to old to dive anymore so appreciated any help.
Thanks
Thanks
