I've got it and I'm happy with it, but if I had to do again, I'd buy a different computer.
Below I'll list some pro's and con's that I found about it. that might help you.
Here's what I like about it.
- I like it's small design
- the fact it has more than one button which makes it easier to use
- it time and date stamps each dive, which is great for reviewing later so you can determine the dive location by the date/time in accordance to your max depth, time, etc.
- easy to use.
- user changeable batteries and uses off-the-shelf (cheap) batteries you can buy at Walmart.
- Has a 3 minute safety stop countdown at 20ft. This is a nice feature that is on a lot of computers but not all.
- The above 3 min safety stop doesn't reset if you go way above or below the 20' mark during your safety stop. (it does on some computers).
- You can set the % O2 to be the same for every dive within a period of when the computer is powered on. This is a nice feature on a liveaboard trip where your fills are typically all the same exact F02 Percentage from a banked supply all week long. This keeps you from forgetting to reset it and having it set 50% for PO2 Calcuations and 21% for Nitrogen loading calculations on a follow up dive, reducing your NDL.
- It's a good computer for the money.
- Hockey Puck design will fit in most traditional consoles or wrist mounts.
What I don't like about it:
- Not all the dive details are on one screen. You have to push the button once to get max depth and a second time to get wate temp. On my other computer all dive details are on one screen during the dive and I can check them all at a quick glance w/o having to push buttons.
- Temp sensor is extremely slow to change. You can be in 10 to 20 degree colder water under the thermocline for 10 or 15 minutes before it catches up.
- Temp is not available after the dive unless you use the download kit
- it only does one gas. A second gas would be nice but not always a requirement.
- You can't set Po2. It's preset to 1.6 (and not 1.4)
- You can't change the conversitiveness of any of the values.
Now this doesn't mean you shouldn't buy this computer. If it's a good deal and works for what you want, then get it.
If I had to buy a different computer today that was similar but had all the features wanted above on the 2nd list, I'd prob look at the Tusa IQ-700. It runs about $379 bucks and does most of all the above. (BTW... Dive Rite makes the same computer as the IQ-700 with a different logo on it).
If I had to buy another computer, I'd keep it as a backup and wouldn't sell it or anything. So it's still pretty decent.
BTW... you can download the users manual off Genesis' website to review before you buy and see how you like the features and screens.
Hope all that helps some.
