>>>> Don't quote me on prices -- they are approximate.
Suunto D9 is a great hoseless computer. Has an integrated digital compass which very well. I was pleasantly surprised. This is my main computer, I dive it all the time. It is pricey.
Suunto also makes the Vytek which is a hoseless computer which is around $1000-1100. The Vytek is a hoseless cousin of the Cobra. This is a computer I dived with quite a bit a few years ago. One of my favorites. The nice thing is the Vytek is upgraded and now includes Deep Stop Technology (like the D9). For a new diver, this doesn't mean a whole lot, but you won't be a new diver forever.
Suunto also makes a Cobra which is NOT hoseless. But has great features. One of the things I like about the Cobra is all your pertinent information is on one screen. If you get the Cobra, purchase the attached compass as well. The Cobra runs about $500
Suunto also makes the D6 which is a non-air integrated cousin of the D9. Same functionality, no air/psi readings. Runs about $600 less. You would need an SPG with that.
Suunto also makes non-air integrated (need an SPG) computers like the Mosquito and Stinger, etc. They run from $250 to $500.
Oceanic has a couple of nice hoseless computers including the Atom and the VT3 (upgraded vtpro). A lot of deep divers prefer the Oceanic decompression algorythm over the Suunto RGBM decompression algorythm. (Again, doesn't mean much to a new diver, but I always say, buy equipment once -- buy it right.) I own the VT3, nice computer. The Atom (for me) is too small to read. Must be getting old. Both computers have gas switching capabilities which is nice as well. Depending where you buy the computers, they will run from $800 (for the VT3) to $1300 (for the Atom).
I have noticed some folks recommend the online stores for purchasing equipment. I have little problem with that (as long as they are authorized dealers). If you purchase from unauthorized dealers, you may void the warranty. However, one of the advantages about buying your computer at a Local Dive Shop (LDS) is the personalized service. I can't speak for every shop, but if you buy a computer from our store, we will (1) show you how they work, (2) go through all the features and functions with you one on one, (3) even let you throw on your equipment and jump in the pool and try them out. When you have an issue (that includes an issue with you) you can drive over and ask questions. You may save a few bucks through an online store, but when your computer goes bust two days before a trip, you have no options. When you purchase it through an LDS, you can go down and speak with someone face to face -- that day. Great service is the ONLY thing that keeps Scuba shops in business.
I am sure this posting will spark some debate about online vs. bricks and mortar stores and I mean no disrespect. Just my personal experience.
There are many other brands of computers out there. Since this is a major purchase, I would visit several scuba shops (each one carries a proprietary line) and buy the one that best suits your diving -- a year or two from now. Make a list of what impresses you and compare apples to apples. The good news is while doing your due diligence, you will learn a lot about the shops in town. It's worth the trip.
