Good link Greg to Alex’s videos. This brings to mind how old experienced Instructors must strive to stay current regarding everything. Moral of the topic...So don’t worry about the front of the SPG, point the rear down range. I have seen many temporarily wrap it inside the BCD (like a flack jacket) and then pull it out and read it after turning the valve on. The was the second part...turn the valve all the way on and leave it there.
