Garmin Descent MK2S Dive Computer is the latest dive computer from Garmin that is a smaller, watch-style dive computer that features multiple modes as well as multisport training and smart features. It allows you to choose from multiple dive modes for whatever your underwater adventure entails. Additionally, it measures your performance and tracks your stats above the water. It also boasts more sports apps such as golfing and skiing and features Garmin Pay contactless payments, music storage and notifications. The Garmin MK2S also allows you to share and review dives in the Garmin Dive App! You won’t have to worry about battery life as when the MK2S is in smartwatch mode its battery life lasts up to 7 days.

With the Garmin Descent MK2S you get multiple dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather. The dive modes are all customisable allowing you to add additional screens for each dive mode that feature the fields you want to see. With advanced satellite connectivity, you can also track your entry and exit points and you are also able to log your dives on the Garmin Dive App which can store and review data for up to 200 dives. The MK2S is compatible with inReach meaning it can be paired with inReach satellite communicators.

You can also use preloaded activity profiles for trail running, swimming, running, biking, hiking, rowing, skiing, golfing and more. It even has surf-ready features for when you’re out in the surf. Use the Surfline Sessions app on your compatible smartphone with your paired Descent Mk2S dive computer to create a video of every wave you ride in front of your Surfline camera. Watch the videos later to see how you did.

Through wrist-based heart rate technology, the Descent MK2S gauges activity intensity as well as heart rate variability to calculate your stress level. It also tracks underwater without a heart strap. For altitude acclimation or sleep monitoring, a Pulse Ox sensor uses light beams at your wrist to gauge how well your body is absorbing oxygen. It also allows you to track how you’re breathing throughout the day, during sleep and during breathwork and activities such as yoga. Through advanced sleep monitoring get a full breakdown of your light, deep and REM sleep stages as well as Pulse Ox and respiration data. View it all on a dedicated widget that includes your stress score and other insights.
