Scuba Diving is an interesting thing.  There's a lot of ocean science involved.
1_Wizard
Of course yes. It could be called  a science when the diver uses a self-contained underwater breathing apparatus

How far down can scuba divers go?
1_Wizard
I think that depends on the source of breathing. Gas or compressed air which allows them them greater independence and freedom of movement

If they use gas as the form of breathing, at what depths can scuba divers descend?
1_Wizard
I am telling you that they can go at any length as long as it is habitable for them. Sometimes they  include additional cylinders for decompression gas or emergency breathing gas.

How much weight does the scuba gear weigh?
1_Wizard
We do not have a unique or defined weight for these equipment. But  scuba set which t is only the diving equipment which is required for providing breathing gas to the diver should be big enough
