Questions & Answers

Brian B : Can this be detached to fit in a console?darrick c : Hello Brian, The wrist version cannot be broken down to mount into a console. They do offer a 2 gauge and 3 gauge console with the i300c. Unfortunately if you wanted to upgrade your wrist and place your old one in a console it’s not possible.Brian V : The wrist version cannot be broken down to mount into a console.

SONYA G : Would the strap be able to fit snugly on a small wrist? Looking for a first dive computer for a 10-year old.darrick c : I measure 5 1/2"- 6" on the tightest position on my i300C. Consider wrist diameter with long sleeve garment or wetsuit.Gary T : I measure 5 1/2"- 6" on the tightest position on my i300C. Consider wrist diameter with long sleeve garment or wetsuit.
Joe P : where can I get the owners Manual on line for my i300C Dive Computer?darrick c : Hello Joe, you can find it here: <a href="https://www.azdiveshop.com/wp-content/uploads/2020/01/i300_Owners-Manual.pdf" target="_blank">https://www.azdiveshop.com/wp-content/uploads/2020/01/i300_Owners-Manual.pdf.</a>
John D : Can you switch gas while in decompression?Christopher S : Yes for example if you are diving air and EANX 50 when you ascend to the proper depth pO2 wise it will ask if you are switching to 50%. Note your TTS will not take into account a gas switch so if using air as a bottom gas your TTS could be 30min but then it will drop when you confirm the switch on your computer
Marion D : Where can I find instructions?Brian V : Search aqualung i300c manual and you will find the link (it won’t allow me to post the link here). They only have their manual online as a PDF. All instructions are in that file, as with any new computer I recommend reading through the manual.

After 42 dives...

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.

Excellent computer, possibly a little conservative

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.

Wrong calculations, bad firmware, Aqualung does not care to fix it

The computer would be ok for a beginner but unfortunately it has firmware problems: it does not compute, nor log correctly the average depth... I sent several emails to Aqualung about the issue with details and they are ignoring me. I?ve opened a thread on Scubaboard and someone figured out what the software is doing wrong, so all the details for a fix are there and have been sent to the manufacturer last year. Unfortunately Aqualung does not stand by their products to fix them. Way to go with life supporting equipment... very disappointed with this manufacturer and I can?t trust this computer anymore. Who can say if the NDL or all the other calculations are correct?!

Great first dive computer

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 a bungee mount or different strap as an option for this computer.

Solid computer, does what it’s supposed to do, easy to use the two button feature

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

Easy and Convenient Interface

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.

Easy to Use

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.

Great computer. Great price.

I have used it on a hundred dives and have bought two for my grandson and his friend as well as one for my wife. I would by another if I had a need. My grandson and his friend did their first dive trip with us in Cozumel and had no problem using and understanding the computers.Great

Really a good computer.

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 the same way. God Bless All.
