I just returned 3 weeks ago from doing 25 dives for a week on the Turks & Caicos Explorer, max depth 165 feet, and dove my new Apeks XTX 200 for the first time, and I was extremely impressed with it's performance! I'd never even dove an Apeks reg before, much less owned one, so I bought it based on the many positive reviews I'd read, but I can confirm it's a very nice regulator. ( I also dive own Poseidon Jetstreams/ Mares Ruby / Atomic B1/T2, so I'm familiar with using 'high performance' regulators. ) I've never owned/used an Oceanic reg, so I can't comment on them, although I own/use a pair of Oceanic Datamax Pro Plus AI computers, which I've been very happy with...although I did have one just fail on my T&C trip, which I had to ship back to Oceanic for repair/replacement, my understanding it that Oceanic has shipped a replacement computer back to me, which I should receive any day now.......I don't know for sure if it's my repaired computer or a new replacement.
