Scuba equipment combines life-support gear with accessories. The regulator system includes a first stage on the cylinder, a primary second stage you breathe from, an alternate air source and a gauge or transmitter. Buoyancy control devices (BCDs) come as jacket-style, back-inflate and backplate-and-wing designs, with integrated weights on many models. Dive computers track depth, time and decompression limits, as wrist units or consoles.
Exposure protection depends on water temperature: shorties and thin full wetsuits for warm water, thicker wetsuits with hoods and gloves for cooler water, and drysuits for cold water. Divers also need a mask, fins, snorkel, weights, a cutting tool, a surface marker buoy, dive lights and a gear bag.
Scuba diving requires training and certification from a recognized agency, and you should dive within your training. Regulators, BCDs and computers need regular servicing by qualified technicians, and cylinders need visual inspection and pressure testing on schedules set by local rules. Have any used life-support equipment serviced before diving with it.
Choosing scuba equipment
- Get trained and certified by a recognized agency before buying or using scuba gear.
- Have used regulators and BCDs serviced by a qualified technician before diving.
- Check cylinder visual inspection and pressure test dates, which follow local rules.
- Choose wetsuit thickness or a drysuit for the water temperatures you dive.
- Pick a dive computer whose features and display suit your diving and training.
- Try BCDs and wetsuits on with the seller's size chart, since fit affects comfort and trim.
Questions about diving equipment
Is it safe to buy used scuba gear?
Many divers do, but life-support equipment like regulators and BCDs should be serviced by a qualified technician before use, and cylinders must be within inspection and test dates. Ask for service records.
Do I need to be certified to buy scuba gear?
Rules vary, and some sellers or dive shops ask for proof of certification for certain items or air fills. You'll need certification to dive with it.
What wetsuit thickness do I need?
It depends on water temperature and how cold you get. Thin suits work in warm tropical water, thicker suits with hoods for cooler water, and drysuits for cold diving.
