Although it’s my backup, I’ve still used my Oceanic Alpha 10 for the entirety of some dives, to see how it performs and check it’s still operating properly.
Every time I use it, I’m always surprised at the comfort provided by its orthodontic mouthpiece.
Despite only being constructed from only one material (unlike say the Oceanic Delta 5 mouthpiece which is dual-material), the Oceanic Alpha 10 mouthpiece still feels soft and doesn’t cause any aches or discomfort in my jaw. So far, so good!
It features a pneumatically balanced mechanism which for many years was only seen on luxury-end scuba regulators but which is becoming increasingly more common in cheaper regulators.
A pneumatically balanced mechanism makes the first part of the inhalation cycle easier – I’ve found it certainly does feel pretty effortless breathing through the Oceanic Alpha 10.
RE breathing what’s also really nice is the fact that it features an airflow control dial (aka Venturi switch) which you can turn to increase or decrease airflow.
This is really useful for ensuring airflow remains constant as if you can’t adjust it, it will change as you dive down deeper. It’s worth mentioning that this airflow dial is pretty basic – you can only turn it about 90 degrees and it’s a little stiff to operate.
Airflow dials seen on more expensive second stage regulators – such as the Oceanic Delta 5 can turn three hundred and sixty degrees and require less effort to turn – i.e. they’re not stiff.
BUT in the Oceanic Alpha 10’s defence, it still does have an airflow restrictor – which other scuba regulators at its price range do not!
So basic though it may be, but I’m going to count it airflow restrictor dial as a big tick in the favour of the Alpha 10. Huzzah!
Simple though it may look but this is a tough and durable regulator and it can also operate in temperatures as low as 4 degrees celcius making it suitable for cold water diving.
Alrighty! We’ve covered the various features of the Alpha 10 – time to wrap things up!!
