fgray1:Every Instuctor has at one time or another solo dives.
If he's with a student he has to not only has to save himself but the student as well. Solo divers are surpose to have the right gear for it. The only differance is where the gear is located.
For that fact Solo divers don't have to worry about swimming to the gear because it's already where he can reach it.
This is not accurate at all. I don't dive with any one unless I think they can perform the basic functions of a buddy and that includes students.
If you look through the small number od posts in this forum it will quickly become clear that not all solo divers have redundant equipment.
