I also have a Suunto Eon Core which I’ve used for nearly 1,000 dives. I’ve been using the Apple Watch Ultra here in Cozumel for the past two weeks doing 2-4 dives a day with 20 dives completed. I’m an Advanced diver with over 1,000 dives in my log. Think about whether looks are important, what features you need, how often you will use it and how much you want to spend. I always read reviews and talk to people about their equipment before buying anything. In some parts of the world they can be a status symbol (like the sexy Suunto titanium range) and in other places they almost never see them. If you’re not near a service shop when the battery goes be prepared to live without it for a little while whilst you wait.Ĭomputers come in all sorts of shapes and sizes, have different features and big cost differences. Some computers have built in GPS allowing you to tag a specific coordinate to navigate towards – such as your dive boat.ĭoes your computer have to be sent in to a dealer to have the battery changed? These computers will cost you a bit more in the long term as you will have to pay each time. I have heard mixed opinions about how useful and accurate they are. They are supposed to be a little less sensitive to having to be perfectly level and can remember headings for you. Some computers have an electronic compass. Some will even manage multiple blends and allow you to switch between them during a dive. They will also tell you how quickly you are consuming your air and will calculate how much time it will take you at your current depth before you use it up.Īnother great feature available on some computers is keeping track of different gas blends and oxygen exposure when diving with enriched air and Nitrox. Some computers wirelessly connect to a transmitter in your first stage and can give you information about remaining air pressure. Is it useful to you having one device that does both? Not all watches work very well when regularly exposed to pressure at depth and not all computers can be worn around town. Yep, whether I’m timing a student breathing from a free flowing regulator or trying to figure out when the bar will close I know my dive computer is there. This is especially good when I am teaching students to do a controlled emergency swimming ascent “if you start to hear beeping, slow down”. I also find the rate of ascent alarm useful, which lets me know when I am going up too quickly. I use my safety stop one a lot, which I have set to let me know when I get to 5 meters (16fsw) and then counts down 3 minutes. I never want to hear the 5 minutes of bottom time remaining alarm, but it has been helpful sometimes when I was distracted. There are various alarms that you can set on some computers to let you know when stuff happens. Some will even connect to your computer, automatically filling in an e-logbook and giving you detailed graphs and statistics. This is great for people like me who don’t like to get their logbooks wet and prefer to write it all down with a beer at the end of the day. Your computer will remember details about your last dives just like a logbook.
