I have used my i300C on 42 dives, 18 dives over 100 feet. I can see my no deco and depth pretty clearly without my corrective lenses. The audible tone comes through clearly when an alarm level is exceeded. The blue tooth allows me to download the dive to a logbook on my phone for review. Easy to adjust between air and nitrox mix. Safety stop timer starts automatically at set depth. I had to replace battery once, fairly easy with included tool.

Simple and good dive computer. It have all what you can expect from it. It's perfect for holidays dives. All necessary settings are available straight from computer or via app on mobile phone. Easy in use. I used it only couple times to this moment but I thinking to use it for longer. Someday will be perfect as a bottom time measure and spare computer.

Brilliant bit of kit for the price. Very feature rich, and super easy to set up once connected to a mobile device via bluetooth.Would be 5*, but lost a star due to the backlight being slightly underwhelming, and the buttons not being the easiest to press in thick gloves.

Love this computer! It is very simple to use both in and out of the water. Bluetooth settings and data transfer works great. Under water stops, and key data is accessible and very easy to use. Just wish it came with both a long and short strap.
The Aqua Lung computer has a large face with easy-to-read numbers. It's two-button operations make it a breeze to set and adjust to the type of dive you are doing. It is hard to believe that such a good dive computer is so economical. I would recommend it to anyone, unless they wanted air integration.
Easy to use, easy to see display, alarm is loud enough to hear. Used on about a dozen dives so far, possibly on the conservative side for no-deco dive times compared to my old Oceanic computer (even though I turned off the conservative mode) but will have to check and compare the printed manual algorithm stats to see for sure, since it's been a while since I've been able to travel to dive.
This has been a great first dive computer so far. It's easy to read at a glance with the bare minimum information you need. The dual buttons make navigating and adjusting settings on the fly a quick process. The bluetooth works as advertised for easy connection to your phone to download dives or update a lot of settings at once even quicker than you can on the computer itself. The PZ+ algorithm hasn't sent me to the surface too quickly with conservative mode turned off when diving along side others with different computers. All in all, its great for a beginners puck style wrist computer, or backup. The downside for me is the strap, its too long when wearing only a rash guard and I haven't found a way to easily secure it so it won't be in the way. I would really like ...

Seems all different brands of dive computers give different data. I am used to my Aries (Manta) and know if it says you have one minute of bottom time left you have exactly one minute before getting "bent"; no forgiving for me. Comparing the i300C to my manta gives me the same depth reading but is about 3 minutes "forgiving" or 3 minutes less bottom time then my known Manta. I suppose I feel a little "robbed" with the (AL) but trust it with my life. The other matter I have with the i300c is the placing of dive numbers. The depth reading is normal for me at the top of the display, but would prefer the (bottom time remaining) to be at the bottom right of it; no-big deal,The importance is it works extremely well, a very well built product, and works time after time ...

First and only computer I’ve owned so far. I put three dives on it and I like everything it does. It came out of the box with a battery that already needed replacement so that was not a good thing. Once you download the DiverLog+ app which is free, linking the Bluetooth and setting your alarms and other various points is very easy. Very happy with this computer
I thought the SPG was in Psi but it's in Bar. Not a big issue but not what I was expecting. Also, the instructional CD was provided however, I don't have any devices that play CDs. MACs don't have them so I had to go through a tutorial on Youtube. I'm still trying to get totally familiar with all the settings. Overall I'll enjoy it more once I.m able to work all the functions.
