Straight off the bat, the Oceanic Delta 5 Scuba Regulator is extremely comfortable in my mouth thanks to the dual-material, orthodontic mouth piece which features bite tabs to relax the jaw.
Orthodontic mouth pieces such as this have been specially designed to accommodate for the natural overbite of the mouth.
I also found the mouthpiece to be noticeably softer than that of other regulators meaning I don’t get a stiff jaw after using it for days on end such as when I’ve been liveaboard diving.
Some online reviewers have said that the mouthpiece is a little too small for them – they must have pretty huge gobs though, because I did not find this to be the case at all!
Next up, the Delta 5 is an excellent regulator for use in all different water temperatures – it is great for diving in tropical waters and as a cold water regulator.
I’ve used mine in places including Egypt and the Maldives where the water temperature can be as high as 28 degrees Celcius – and I’ve also used it in Irish waters with a temperature of just 14 degrees Celcius! It worked great in both conditions.
Generally, scuba regulators don’t require any special features to work in warm water. They do however require modifications to work in cold water – which the Oceanic Delta 5 has: As well as featuring ribbed heat exchangers it also features a heat exchanger positioned on its hose connection port.
Whilst you can purchase the Oceanic Delta 5 (i.e. the second stage) on it’s own, you can also buy it with the eDX first stage which I recommend as the eDX features an all-metal valve to ensure even better heat transfer and greater all-round durability.
If you do buy the whole package, which I recommend, it’s good to know that like the Deota 5 second stage, the eDX first stage also features ribbed heat exchangers to further enhance cold water use.
Another incredibly cool feature on the Oceanic Delta 5 – and something you don’t see in cheaper dive regulators is the dynamic airflow adjustment control. Simply turn the dial on the side to increase or decrease airflow.
The advantage of this is that airflow tends to change with pressure. But with an airflow control dial you can ensure it doesn’t by quickly and easily tightening or loosening it.
You can also adjust the airflow dial depending on your own style of breathing – some people are naturally heavier breathers whereas some take faster, more shallow breaths. Whatever is the case for you, you can adjust the airflow of your Delta 5 to suit your breathing style best and so conserve air.
Whew! That’s a lot of awesome features and functionalities we’ve covered there. Time to sum up the Oceanic 5 Scuba Regulator:
