Bought this refill adapter as a gift for my boyfriend. Now he can top up at home and not rush through his dives worrying about low air.

I use this adapter with my main tank and pony bottle. The parts feel durable, and after many refills the gauge still reads accurately and clearly.
Megan Q.
I was surprised how compact this refill adapter is. It tucks into a side pocket, yet the gauge numbers are big enough for my not-so-great eyes.

I’m not very handy, but this refill gear is simple enough. The instructions were clear, and now I don’t have to plan my dives around shop hours.

Got this for my brother who dives every weekend. He said the gauge is spot on and filling takes only a few minutes, even on busy days.

I like gadgets that just work. Hook it up, watch the gauge, close it off. The whole refill takes less time than loading the rest of my gear.

We dive off our small boat most weekends. This adapter packs neatly with the rest of the gear and lets us refill between short shallow dives.
