When divers talk about regulators they are usually talking about a complete set of regulators which is typically made up of a first stage, hoses, a second stage, a redundant second stage (normally referred to as an Octopus) and an instrument console (which can include pressure gauge, depth gauge, compass or possibly a dive computer)
All of these components can be bought individually but manufacturers match suitable elements together to create pre-assembled packs to meet a number of uses and environments that both recreational and technical divers typically find themselves in.
When it comes to choosing your regulators it is very important to bear in mind what sort of diving you intend to do and the environments in which you will be diving. For example, if you intend to only dive to normal recreational limits whilst on holiday in tropical location your choice of regulator is not necessarily going to be anywhere near as demanding as a diver descending to 50m + in water temperatures below 10°C (below this temperature is considered to be cold-water).
At Dive Wimbledon we recommend the following:
Warm water diving:
Scubapro MK2 Evo with R195 second stage, R095 octopus and compact double console
Light weight for travel: Scubapro MK11 with C370 second stage and R095 octopus with compact double console
Cold water diving or a higher specification regulator:
MK17 Evo with S600 second stage and R195 octopus and compact double console
MK25 Evo with S600 second stage and R195 octopus and compact double console
There are also a variety of different models and specifications available within the above and these can all be found on the Scubapro website here.
