I'm actually fairly surprised to hear people running Zeagle gear for tech. Not that it's bad by any means. I personally dive a Zeagle Brigade BC myself and love it for the type of diving I do. Just usually hear more about Dive Rite, Apeks, ScubaPro, OMS, and Hollis for tech gear.
I've never seen a cave diver in zeagle gear. And I'm a zeagle dealer. There might be some people diving it. But I'm at the busiest cave in the world weekly, and I'm not seeing it.
