Garmin Descent Mk2i


Key specifications

The Garmin Descent™ Mk2i comes with delightful features to work with. Some of the key features are as follows.

Advanced style

One will be amazed to see how such a compact device has so much to offer. The Garmin Descent Mk2i diving computer is styled as a watch that can easily be strapped on the wrist while diving. It has a 1.4” display screen, making visibility clearer and better. It has a color display that is readable even in sunlight.

Diving features

The dive computer comes with six different dive modes. It also has an ABS sensor along with the multi – GNSS support. The Garmin Descent™ Mk2i has an inbuilt underwater compass that helps you know the entire path of your dive from beginning till the end. It also has a sensor for heart rate monitoring and Pulse Ox.

Storage capacity and battery life

The Garmin Descent Mk2i dive computer has an exemplary storage capacity that enables you to store data of up to 200 dives. You can review this data on the Garmin app on your phone that can be paired with the dive computer.

It also has a considerable battery life of up to eighty hours when being used in dive mode. When used as a smartwatch, the battery lasts for up to 16 days. When the GPS and music feature is in use, the battery will sustain for about 15 hours.


What are the various diving features of the Garmin Descent™ Mk2i?

The Garmin Descent Mk2i diving computer is designed to make the diving experience unique and safe. It is loaded with features that assist you throughout the dive. Be it information regarding body vitals, or anything related to the diving equipment, it has everything that you need set on your wrist.

Here is a detailed description of the diving feature of Garmin Descent Mk2i.

Air integration and SubWave sonar

The ‘i’ in Mk2i stands for air integration. This feature is an improvement over the previously existing model. The air integration feature, along with the SubWave sonar, makes the subwave network.

The combination of the two technologies shows the utilization of a sonar-based communication system instead of the commonly used radio-frequency method. A sonar-based system provides a broader range when it comes to signal strength underwater. It holds the ability to support up to five transmitters.

One dive monitor can, therefore, be used to monitor the air pressure of even the other divers around. This makes it a suitable option for an instructor.

A disadvantage of this technology is that this wireless transmission setup is a proprietary product of Garmin. Therefore, there will be compatibility issues with other transmitters.

Multiple dive modes

The Garmin Descent™ Mk2i dive computer comes with various pre-loaded dive modes that increase its demographics when it comes to types of divers.

·       Single gas

The single gas is a recreational dive that only uses a single tank. It, however, does not restrict the diver. One can easily switch to an alternate gas mix while underwater.

·       Multi-gas

It is a mode useful for open-circuit technical divers. It allows up to six different combinations of oxygen and helium as well as back up gas and decompression mixes.

·       CCR

This mode is for the rebreather divers. One can see the PO2 decompression calculations with it. It also comes with six bailout gasses.

·       Gauge

This mode enables the interested divers to know the depth and time while diving.

·       Apnea, and Apnea Hunt

These are used for freediving.

You can easily customize each dive mode by adding different screens. Based on the features you wish to use and the activities you want to monitor, you can customize the screen to your suiting.

Surface multi-GNSS and dive logs

When underwater, it is not possible to run GPS tracking. Thus, you need some technology to either guide you or track your path. The Surface Multi-GNSS feature of the dive computer provides advanced satellite connectivity that helps in noting the entry and exit point of the diver.

Also, the remarkable storage capacity of the computer allows you to review data from up to 200 dives at a time.
