I have a seac sub asso 115 pneumatic spear gun. I am very pleased with this spear gun, and it's pressure is about 30 bars. They have told me that this equipment stands a lot more pressure, but some others tell me that if I load more than 22 bars there will be a problem. I wonder if someone of the members of the forum knows anything about it. I ask because I spear with arballets since 1984. Thank you anyway.
