Rating: Itegrated octo with subduck integration
Reviewer: Robert Walker
This is a feature rich integrated octo. Yet its size and weight is hardly much larger than a simple power inflator. Its breathing ability is adequate for a safe accent although not as good as other integrated octos that rival mainstream primary second stages. The layout of the controls is not as instinctual as others this may be due to the need to fit a third button for the subduck. The layout has the inflator button is on top the deflator is on the bottom and the signal is on the side. It is not difficult and with use does seem to become a very controllable inflator. The appearance of the control buttons is toyish and cheap time will tell it holds up well to use. Sound from the Subduck is easily heard underwater on the surface although not as loud as other surface horns it can be heard for quite a distance. Im happy with this devices out of the box performance after using it for a few dives. If it holds up well long term Id give it another half star and if the breathing ability can be adjusted for better performance it would deserve a 4.5 star rating the last half Id withhold due to the control layout.

Rating: A Great Octo
Reviewer: Paul P.  -  View all my reviews
I just had the Air 3 put on my BCD and in a test dive it worked great. No air leaking and the horn is LOUD. A great little package. One less hose to think about and that is a winner in my book. As my octo my dive partner may be a bit close but I dont mind...shes cute!

Rating: Aquatec Air 3
Reviewer: Milton Heather
This product was very easy to install. It is a very easy breathing and smooth octo. The horn works very well and is very loud. Great to signal in high waves. The cluster of buttons for fill and deflating took a little while to get used to, but overall it is an outstanding item. I definitely recommend this item.

Rating: Great idea for little price
Reviewer: Gary Honeycutt  -  View all my reviews
This is a great idea. You get a BCD inflator, a stage two Octo and a an emergency signaling device for signaling both above and below surface. Easy to install and works like a charm. It even removes one more hose.
