How heavy is scuba gear?

Answer 1

Scuba means self contained breathing apparatus and it was actually a bit lighter in the past than today because divers tended not to wear dry suits and had lower pressure air tanks.

I think you are referring to standard dress, heavy dress or hard hat diving suits. These had big brass helmets and heavy weighted boots. The helmet displaced many litres of water and the suit contained air too, As a result the helmet was heavy as were the boots and divers often put additional chest weights on. The all up weight of the suit, boots and helmet was well over 80kg. People who used these suits stood on the floor to work, so even more weight would sometimes be used to help with some tasks. Standard dress as it is known is not used very much in the West and are generally only kept by collectors but is still used in Asia for commercial diving work.
80 kgs or about 170 lbs

Answer 2

While scuba equipment is very heavy on dry land, when underwater, the weight of the equipment is alleviated on the divers due to the water buoyancy. Even weak divers have little trouble with managing the equipment.
