Like its predecessor, the new Descent Mk2 has a digital compass, GPS, five dive modes and a variety of fitness functions such as heart rate monitoring and sleep tracking. Now it offers pulse oximetry, and its screen is roughly 15 percent larger while only enlarging the body by a millimeter. The more expensive Mk2i ($ 1,500) is paired with Garmin’s new T1 transmitter, which uses sonar to monitor five different tanks up to 30 feet away.

Core body temperature sensor ($ 285)

Until now, determining your internal temperature in real time required complex measures such as swallowing an electronic pill. Core Body Temperature’s new sensor tracks thermal energy transfer for incredibly accurate readings. Wear it under an included waterproof sticker or over a chest strap (BYO). It pairs with Garmin and Wahoo devices to provide up-to-date information so you know when to sit back or press harder.

Apple Watch Series 6 Smartwatch ($ 399)

Apple’s Series 5 was already the best smartwatch money could buy. This year’s update features blood oxygen monitoring and sleep tracking. It also integrates with the new Apple Fit subscription training platform. It still doesn’t work with Android, but if you have an iPhone, it remains the everyday wearable to beat.

Airofit Pro Breath Trainer ($ 299)

The Airofit Pro looks like a high-tech face mask, but it is actually a tool for strengthening your lungs. It is combined with a phone app that does exercises to build breathing strength, vital lung capacity and anaerobic threshold. It’s perfect for helping freedivers and surfers hold their breath longer or give endurance athletes a boost.

Polar Vantage V2 Smartwatch ($ 500)

The Vantage V2 offers more detailed data than any other watch we tested. In addition to typical metrics like GPS, optical heart rate, and sleep tracking, it offers leg recovery and VO2 max tests (both run- and bike-specific versions of the latter), as well as a feature to notify you when it’s time for more calories. Another function breaks down all your data for going up and down in run or bike mode, including pace, distance and vert. Nevertheless, the watch only weighs 52 grams.

Bose Sleepbuds II headphones ($ 250)

Forget about streaming music. These headphones are only intended for sleeping. They’re small enough to fit deep in your ear (you can even wear them on your side to sleep) with rubber tips to block out noise. Use the Bose app to download a soothing soundscape like a waterfall or ocean straight onto the buds. Then, disconnect from Bluetooth and listen for up to ten hours. They’re expensive, but it’s worth getting a good night’s sleep.
