The Mares Puck Pro is a great computer with a very palatable price point. It gives lots of great features while keeping things simple and clean at the same time.
It has only a single button (hard to press the wrong button!) and keeps all important information like depth, time, and no decompression limits on the main screen while diving.
It can handle Nitrox mixes as well, just input whatever percentage you plan on using and it will calculate your NDLs for you.
A long button press will bring up a backlight, useful for low visibility dives and night dives to keep an eye on your info.
When ascending, it will show where to conduct your safety stop, and for how long as well. For those with a stylish flair, it comes in a huge multitude of colors as well!
Some people are worried about buying a lower level computer and wasting the money that they could be spending for a much better computer, either for just improvements or for technical diving.
This computer is a good investment even for that, as it has a great gauge mode that tracks depth and time.
Many technical divers will use a computer only for depth and time and will run decompression tables with software, using the gauge mode with seconds timer to conduct their stops.
Some will have a primary computer with the timer and tables as backup for an extra layer of safety.
Either way, this computer will not be a waste for higher levels of diving, and it will satisfy all your needs for a recreational computer as well.
If you want to get a better look at your dive data, a connection cord is sold to connect the puck pro to a computer, where you can download the dive data to software on your computer.
The Suunto Zoop Novo and Vyper Novo are very similar computers, with the Vyper offering a handful of quality of life upgrades over the zoop.
The zoop offers a full recreational computer with 4 buttons for easy operation, and a relatively cheap price point.
With a large, easy to read display and long push backlight, all the information is easily available, with the ability to scroll for additional information like time of day, water temperature, and more!
It has a separate modes for nitrox, planning, and gauge (which is simply a depth and bottom timer, great for technical diving as well).
The menu system is easy to navigate and intuitive to use with the multiple buttons.
You can plan future dive depths and times on both air and nitrox and it will calculate different no decompression limits, great for during the surface interval to see what you can do for your next dive.
A separate cable is sold to allow you to transfer the data to your computer.
You can log it in a number of programs, but Suunto has their own Suunto DM5 software that connects with your computer to give status, dive info, logs, and even allows you to plan dives!
The Suunto Vyper Novo is very similar to the Zoop, but offers several important upgrades that make it superior. It has an electronic compass which is accessed with a long press from the regular dive mode.
This allows seamless use of the compass to find your way or set a direction at any time during a dive, without having to carry a separate compass! In addition, it offers the ability to switch between 3 different gasses that you set yourself. Lastly, it offers the highly sought after air integration option.
With a separate Suunto transmitter, you can wirelessly monitor your gas reserves throughout the entire dive, right on your wrist! This is perfect for those looking to streamline their dive experience.
Either of these two computers will suit all your recreational diving needs, as well as be a great gauge mode for technical dives. With lots of features and an easy to scroll menu system, they’re both great computers for a diver of any level.
Some people want a dive computer that can do more than simply dive. For them, the Garmin Descent Mk1 is the perfect all-arounder for daily life.
The Mk1 builds upon Garmin's formidable reputation as a maker of GPS systems, smart watches, and activity trackers and combines it all into a small, easy to wear form factor that can withstand any type of diving thrown at it.
- Multi-Gas Technical
In addition to these modes, there are dozens of options such as dive planning, gas selection, 3 axis compass, and GPS/GLONASS capabilities.
When in dive computer mode, it will last approximately 40 hours, allowing plenty of dives before needing to be recharged.
It uses the Buhlmann ZHL-16c algorithm to calculate dive information and supports full trimix and decompression calculations with user settable alarms which are both audible and vibrating.
While the Garmin certainly shines as a compact, watch-sized dive computer, it offers numerous additional options for every facet of life.
It can be used as a simple watch with downloadable and changeable watch faces for every occasion in daily life, while looking sleek and stylish as well.
For those who prefer to be in the center of the action, the GPS and GLONASS features are perfect for outdoor activities, and the Elevate™ wrist heart rate technology lets you monitor the heart rate anywhere from the gym to hiking and kayaking.
It includes most of the features from the Fenix 5x multisport watch, like fitness tracking, running dynamics, and physiological metrics.
In addition to all of these features, the Mk1 offers full smartwatch features as well. Connecting to your phone gives you the ability to get messages, emails, updates and more right on your watch!
For a device that you can wear anywhere from the dive boat of a trimix dive, to your morning run and workout, to a sophisticated dinner at the islands best restaurants, the Garmin Descent Mk1 really can do it all with style.
The Shearwater Perdix AI is THE top of the line dive computer. This computer does it all and does it with style, reliability, and user-friendly interfaces. It boasts an easily readable 2.2” screen with full color and adjustable brightness settings.

The recreational mode offers 3 gasses for use, which you can input yourself for any mix of air or nitrox you will use, with the ability to change them later.
An uncluttered, easy to read display gives all needed data on the main screen, including an NDL timer and graph, depth, time, safety stop timer, gas pressure readout AND gas time remaining calculator (With optional pressure transmitter), and the ability to customize this screen with whatever you deem necessary.
The technical mode offers a multiple user programmable gas mixes including any mix of air, nitrox, trimix, and oxygen, with the ability to toggle during the dive.
When gas is switched, the computer will adjust decompression information accordingly and give information about the gas such as the PP02 at current depth.
Changing the gradient factors will alter decompression times and stop depths, allowing you to plan the dive how you want. As with the recreational mode,there are dozens of options on what information can be on the main screen, and you can adjust it to your liking similarly.
The closed circuit mode offers constant setpoint decompression to make it work with rebreathers of all types. Simply put whatever PP02 you keep your unit at (1.2, 1.3, etc) and it will calculate all decompression and stop times based on these values.
You can also set multiple OC bailout gasses, which can be easily toggled when needed, and the computer will adjust values to match.
Gauge mode offers a very simple depth and time display, as well as average depth and a resettable stopwatch. This mode is perfect for those who prefer to run tables and dive with a simple bottom timer.
All modes come with dozens of extra options such as a tilt compensated compass, tank pressure monitoring with gas time remaining timers for up to two tanks at a time, which is perfect for recreational divers, technical divers, or even rebreather divers (Monitor both DIL and 02 without the need for extra hoses), and an ergonomic design with multiple attachment points for straps or bungee.

Offering perfect options for recreational, technical, and rebreather divers, the Perdix AI is truly a cutting edge and top performing computer with easy usability, dozens of features, and simple reliability.
Frequently Asked Questions
Why get your own dive computer?
A dive computer allows you to track your limits over multiple days and even multiple operators. If you rent a computer from more than one place on vacation, then it won’t be accurate, as you’ll already have tissue loading from previous days of diving.
Having your own dive computer allows you to accurately track your limits, regardless of where you go. In addition, having your own computer allows you to be more familiar with its operation and readout.
Rental computers that you don’t know how to use may make it difficult to scroll through menus or read what it is saying. A personal computer offers not only safety benefits but also quality of life benefits.
