Aqua Lung i300, i750tc Dive Computer Wrist Scuba Computer

For the basic diver/Nitrox diver this is an amazing computer!! it is simple to operate and program. I have had zero issues with both of mine. I would also like to shout out to New England Dive shop. I have made two orders from them through amazon. I had to send one item back for adjustment and they were amazing to deal with. When I called to ask about the procedure I spoke with a tech named Greg who assured me that the problem would be take care of. Sure enough one week later my piece of equipment was back in my hands. Aqua Lung makes a great product with the versatility and durability to last. This watch also allows you to change the battery yourself with the supplied tool. I will say I as upset that the sync cable doesn't come with the computer but I guess they just want my last nickel and dime!Don't forget to hit the helpful button.

I like the computer. It's a little big like others have mentioned. I'm not that small of a guy but to get it to fit my wrist I have about 3" of strap past the buckle.If you are on your 2nd tank dive and you get a beep for nitrogen it goes into violation mode and locks up for 24 hours. This is problematic for diving the next day since dive boats usually leave at the same time every day. If it hits the water within that 24 hours the delay starts over and will never clear until you are out of the water for 24 hours.The depth, duration and accent rate still work but it continualy tells you to come up. I get that it's trying to keep me safe but this should be able to be reset.

This is my second dive computer and the Aqua lung i300 is packed with some great features normally found in more expensive models. Quality build and easy to use. I gave it a four star instead of five because of the price of the USB cable. First, I think it should come with the cable even at the price that the unit is sold for now. Second.. it's a USB cable and to charge the outrageous price as an accessory is consumer price gouging in my opinion.

This is a simple, basic dive computer that is plenty sufficient for my needs. I bought a second I300 this year after having a good experience with the one I bought last year (my TUSA computers are getting old and started to act up last year). It looks like I300 is now discontinued and I wanted to buy one of the few still available for a reasonable price (I did not see much sense of paying in excess of 50% more for I300C, just to have Bluetooth capability). I300 is simple to use and set-up for both air and Nitrox, using two buttons. Some reviewers complained about poor visibility of numbers on the screen but I did't see a problem, at least during day dives. The battery is user replaceable, which is a must for me. One thing I like about my old TUSA computers is that, on the surface, they switch to a time mode and stay as a clock until the next dive, next day or next year (does not seem to drain the battery). I300 on the other hand goes to sleep after no fly time times out. Also, I300 can not be reset (for instance it locks-up for 48 hours in case of a deco violation so watch you dive time) so it can not be shared by, say two divers on different days.

Device worked great. Took a little while to figure out what the LCD Text abbreviations stood for, but once I figured it out it was a breeze. Self activated in the water, gave me the max depth and bottom time, as well as tracked when i needed a decompression on ascent, as well as how long it was. It uses the full 24 hours before flight requirements for its 'time to fly' rather than the 12-18 hour requirements. The nitrogen calculation was on par with a friends mare puck. Believe this is a great device for the price and would recommend.

This is a wrist watch depth gage I’ve looked at for a long time. Display is light-induced glowing do help make it easier to see, has a colored tip to the hand and is clear.My negative is the first brush with a rock on my first dive scratched the face of the display significantly. I’ve had the same diving watch for five years, no scratches or scuffs despite grabbing for lobster, and this one scratches on day one. Not thrilled about that.

Awesome dive computer at discounted price! Worked well as we also got certified to dive with Nitrox. Worked great for both Air and Nitrox diving and warming alarms worked well underwater as we may have descended too deep or ascended too fast (not on purpose, of course). Easy to view and easy to configure.

I have only used it twice and the computer won’t turn off. It is supposed to turn off after 24 of a dive and 2 hours when turning it on for logging, etc. Mine is now on continually and battery is draining. Other than this pretty significant issue, I liked it it’s simplicity of use and features.
