The fundamental piece of diving equipment used by divers is theSCUBA breathing equipment.
Personal equipment worn by divers
- Aqualung consisting of the diving cylinder and diving regulator
- Buoyancy Compensator, Buoyancy Control Device, BCD or BC
- Compass for underwater navigation
- Decompression tables to avoid decompression sickness
- Depth Gauge is is used with Watch fron decompression monitoring on decompression tables
- Distance line is used to navigate back to a safe start point
- Dive Computer to avoid decompression sickness
- Suit such as a dry suit, a wet suit or a skin
- Regulator including first stage, demand valve and contents guage
- Fins
- Knife to cut ropes and nets
- Mask allows the diver to see clearly underwater.
- Rebreather an alternative to an Aqualung
- Snorkel
- Torch/flashlight is essential on low vizibility or night dives
- Watch is is used with depth gauge fron decompression monitoring on decompression tables
- Weights
Surface Detection Aids
The purposes of this class of equipment are to:
- allow the boat cover to find divers on the surface after a dive
- prevent the diver being run over by boat traffic on the ascent
- mark the diver's position during a drift dive or while at the decompression stop
- help rescue boats and helicopters to locate the diver
Surface Detection Aids (with cheapest/most effective towards the top) includes:
- Surface Marker Buoy or Decompression buoy (Delayed SMBs)
- Red or yellow collapsible flag - high visibility, robust, bungeed to cylinder
- Whistle - cheap, will only be heard by people far from engine noise
- Strobe - needs long lasting batteries
- High pressure whistle - expensive but they are effective
- Orange water die - for helicopters
- Compact Disk - makes a good, safe mirror of sunlight or searchlights
- Red flares - for helicopters and lifeboats
- EPIRB (Electronic Position Indicating Radio Beacon)
Group Diving Equipment
- Airlift - a gas "powered" tube that sucks small objects, sand and mud from the sea bed that is used in nautical archaelogy
- Decompresssion trapeeze consists of one or more horizontal bars, suspended at the depth of intended decompresion stops by buoys
- Diving shot - a weight, line and buoy used to mark the location of a dive site, allowing divers to navigate to and from the surface and to do decompression stops at a safe location. Typically the weight is 20 kg.
- Lifting bag - a robust airtight bag used to lift heavy object underwater
