It’s simple, a good dive buddy is someone that you entrust with your life. If your buddy is one who goes wondering off, that is not a good buddy. A good divebuddy is there to share the good and bad of a dive. He/she should be by your side and not off in space some where. A buddy keeps track of his/her buddy and watches your back. A good buddy is available if you have a problem or something great to see.
