Air Integration with T1 Transmitter

The included Descent T1 transmitter gives you integrated pressure monitoring on up to 5 tanks via the SubWave sonar data network. It's an ideal option when diving with multiple tanks or to keep tabs on the tanks of a fellow diver. The transmitter relays remaining battery, tank pressure, remaining air time, and air consumption rate for multiple dive types, right to the MK2i's display. You can take the Descent T1 down to a depth of up to 372.9' and data can transmit to your smartwatch from up to 32.8' away. Additional T1 features include:

• Transmits over 2.4 GHz at 0 dBm
• ANT (surface) & sonar (underwater) transmission
• Up to 100 hours of battery life
• Powered by a lithium CR123A 3V battery
• Pressure rating of up to 300 bar (4351 psi)
• 7/16" (20 UNF) thread type
• Operates underwater from 32 to 104°F
• Operates above water from -4 to 140°F
• Can be stored from -22 to 158°F

SubWave Sonar

• Transmit important data for you and other divers within a range of up to 32.8'. It can transmit air time, air consumption rate, and more.

Dive Modes

• The Descent Mk2i supports the following types of dives: single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt, and closed-circuit rebreather. Each of these modes are customizable, letting you add more screens for the fields and information that's most important to you.

Dive Log

• Via the Garmin Dive app, you can store and review the data on up to 200 drives and share that online.

InReach Compatible

• The Descent Mk2i can be paired with (optional) InReach satellite communicators and InReach dive cases.

GPS Navigation

• Built-in GPS support lets you follow a route or course with turn-by-turn navigation. You can also utilize round-trip routing, which lets you enter a specific distance you want to travel, and then provides suggested routes that will get you there and back. With Trendline popularity routing, you can find a popular path or one that's off the beaten path.

Performance Metrics

• View a wide variety of metrics as you exercise, such as running dynamics, heat- and altitude-adjusted VO2 max, recovery adviser, and more.

PacePro Technology

• PacePro helps to keep you on pace with grade-adjusted guidance as you run a course.

Animated Workouts

• It's important to always perform workouts properly to maximize their benefit, which is why Garmin includes animated workouts on the display. These easy to follow animations include workouts for cardio, strength, yoga, and Pilates.

TOPO & Ski Maps

ABC Surface Sensors

• Basic navigation and environmental data is at your fingertips with an altimeter for elevation data, a barometer for weather monitoring, and a 3-axis compass for direction and navigation.

Wrist-Based Optical Heart Monitor

• Gauge how intense an activity is and view heart rate variability to calculate your stress level. It even works underwater without an additional heart rate strap.

Pulse Ox

• This sensor uses light beams on your wrist to gauge how well your body is absorbing oxygen. It's an ideal feature for casually monitoring a respiratory ailment, altitude acclimation, or sleep quality.

All Day Respiration

• The Descent Mk2i can track how you're breathing throughout the day, while you sleep, and during breathwork and related activities, such as yoga.

Safety & Tracking

• If you feel unsafe or your watch senses an incident, assistance and incident detection features will send your location to emergency services. Please note that this feature is not available in Dive Mode.

Play Audio
