Whats the purpose or need for a over presure relief valve for a SMB
Can you buy pouches separatly ? if not how would you suggest you secure it to a BC
Bill(Certified Scuba Instructor at Scuba.com):
The over pressure valve is used when using the SMB as a lift bag. It allows the diver to control the ascent of the bag. Usually you can clip a lanyard or carabiner to the SMB and then attach it to the bc.
