A good basic computer that is easy to use with a tiger in it's tank as you progress. Easy to read in low vis and at nightand in bright sunlight. A true joy to interact with and I am always glad I let my wife talk me out of the cheaper computer. I love my Perdix and she loves hers and we bought them when we had 9 dives in our log book. Best money I've spent on diving to date. If you want to spend less, you obviously can. If you want to love your computer from the beginning, you can do what we did. Dig deep into your wallet and cry once. I would only do this if you are sure that you are committed to scuba diving. If you aren't sure buy on sale next black friday or used from somebody that is upgrading.
