I have dove the same Zoop for almost four years and still going strong. Guiding dives every week and the battery always lasts longer than my friends. Intuitive pathways for changing air to Nitrox settings. They are priced so well I just bought another Zoop as a backup.
The fabric outer covering and increased flexibility of this hose combines for a much more durable hose. The flexibility also reduces work on the neck muscles as you look around. I like being able to choose specific lengths of hose so I can reduce the amount of hose that sticks out from the rig reducing both drag and risk of getting hung up on obstructions in a wreck. Even on new regulator sets, I replace the standard hoses with this hose.
I guide dives once or more weekly and this bag is built to endure the regular punishment. Zipper and fabric and stitching are of high quality and it is backed up by Stahlsacs lifetime warranty. Hard to beat.
Adds just the right thermal protection in tropical waters without a lot of change in buoyancy/weight requirements. Front zip makes it easy and fast donning/doffing. Stitching and zipper are of good quality.
This bit allowed me to order an H2O Rhino hose exactly the right length to reach my inflator controls, streamlining the BCD rig.
Much easier to carry with you on routine and instructional dives.
I have switched my reg completely over to H2O Rhino hoses, more flexible, lighter, durable. I was able to make the inflator hose the perfect length and the whole rig is more streamlined.
