good points, guys.....the only scuba computer I've used is the Suunto Gekko.... (plenty of freediving with a D3, too)....I've heard a lot about the conservative Suunto algorithm - maybe the Galileo is a better choice for that reason alone.... I went to a dove shop yesterday to look at the D9 and the Galileo side by side. Didn't love the D9 - not easy to read....the Vyper size looked better.... but the Galileo is incredibly easy to use, and the digital compass is actually useable..... maybe I could live with the size.....there's even a no-charge freedive software upgrade for the Galileo......
