Underwater diving is a fun sport.
I love it so much!  Even though humans aren't anatomically adapted for it, I love strapping on the scuba gear and hitting the water.  What do you like about it?
I like seeing fish in their natural habitat.
I hear you.  I love to take photos of fish while scuba diving.  It's a lot easier now that we have the right gear.  People used to just strap stones to themselves for a fast descent.
That sounds like a good way to drown!   What sort of breathing gear do you like?
I have a whole set: the breathing apparatus and tank that I put on mt back and carry along with me under the water?  What do you use?
I am looking for something new.    Mine is worn out.
Is all the gear worn out or just the regulator?  The part that reduces pressurized breathing gas and delivers it to you.
primarily the regulator.    The mask should also be replaced.
It might be cheaper to just start doing surface supplied diving.  The breathing gas is piped through a hose from the surface.
