not every dive I do is solo. If im on a job my partner is in sight. If im in a cave I have a TRIED AND TRUE partner. If im on wrecks I keep the overheads simple. Most everything else, im on my own. Quality well maintained gear and and experience is my usual buddy and I have learned to trust both. And I never let my wife anywhere NEAR my stuff,im not sure how to read those ''I swear im going to kill you for being stupid'' remarks.
