Calypso O2 regulator question

[Riverrat Dave]

[I need some advice about an Aqualung Calypso O2 regulator... On their website Aqualung describes this regulator as:

CALYPSO O2
The Calypso O2 regulator has all the same features and benefits of the popular Calypso regulator, with the added bonus of being designed and built for use with breathing gasses containing oxygen percentages between 40 - 100%. The Calypso O2 is an excellent choice for technical divers in need of a shallow-water regulator capable of operating with a high O2 percentage.

What do they mean shallow - water regulator?

The reg is fine for recreational dives ie down to say 30 m on air ,but if your needing deco gas ..its a simple cheap oxy safe reg for use at the max operating depth for the mix needed.
If you needed pure o2 then 6m would be your max depth,hence the "shallow water" tag.

I am looking into putting together a pony bottle and my LDS had this Reg on-sale... I currently use a Sherwood Maximus as primary and an integrated scource as an octo...
but want the totally seperate air scource for back-up...

Its a perfectly reliable simple reg,than will last,plus parts easily available .I have a conshelf 24 that I use as my indestructable primary reg.Its soon to be my bail out reg on my rebreather.
Aqualung models are pretty dependable .And no im not a aqualung dealer!
