Solo diving

[oldtimer]

Solo diving is probably the safest diving you'll ever do as it really forces you to dot your i's and cross your T's.  There are Solo diving classes available now as well as books you can read.  A simple google search will turn them up.
    Be fore warned however that solo diving is not for everyone.  You not only have to be squared away with your kit and your technique, but you have to be there mentally as well. I was taught self reliance many moons ago.  Today, buddy dependence is more of the rule.  In solo diving there is no buddy to bail you out.  It is taught today that the first rule of diving is never hold your breath.  That is very important.  Never hold your breath!  But what is more important is, "no matter what happens to you, do not panic!  Stop, think, react."
      Your research will turn up things like letting people know where your going and only diving as deep as you can make an emergency accent.  There are other things like entanglement scenario's and the like which you may not have considered.  Read, study and be very careful.  The rewards are worth it.  It's definitely a path not to be taken lightly though.
