For just $1399.99, below its 30-day average of $1598.33. The Mk3i has held steady around $1598 for the past three months, so this price cut stands out for anyone who has been tracking it.

If you need a serious dive computer that doubles as an everyday smartwatch. This is one of the few discounts worth acting on.

What You're Getting

The Descent Mk3i is built around a 1.4-inch AMOLED display with a scratch-resistant sapphire lens and a 51 mm titanium bezel. It is rated to 200 meters with metal leakproof inductive buttons, supporting recreational and technical scuba diving plus freediving.

SubWave sonar lets you exchange preset diver-to-diver messages up to 30 meters and monitor tank pressure for up to eight divers when paired with the Descent T2 transceiver. A built-in LED flashlight with variable intensities and strobe modes works above and below water. The dive readiness tool tracks sleep, exercise, stress, and jet lag to help you plan safer dives. DiveView maps include bathymetric contours and over 4,000 dive sites.

Who This Is For

Best for serious divers who want a single device for underwater navigation and daily wear. The Mk3i eliminates the need for a separate dive computer and smartwatch, making it ideal for frequent travelers and liveaboard trips.

Casual snorkelers or occasional divers can save money with a dedicated dive computer and skip the smartwatch premium.

Final Verdict

The 1.4-inch AMOLED display and SubWave sonar alone justify the price for technical divers who want group monitoring and high-visibility underwater data. At $1399.99. This is the lowest the Mk3i has been in recent months, and there is no guarantee it will stay here.
