  • High-resolution screen - The screen is very clear, which makes it easy to see your data no matter how far away you are from it.

Performance and Battery Life

The battery life is insane. Seriously, it blows all other dive computers out of the water. You can get up to 96 hours of GPS running on a single charge, and up to 80 hours in dive mode or 32 hours if you pair it with the T1. That's more than enough for even the longest dive trips.

But that's not all. The Descent Mk2 also has an impressive smartwatch mode. You can get up to 7 days of battery life on a single charge, which is more than most other smartwatches on the market. So whether you're diving or just using it as a regular watch, you don't have to worry about it dying on you.

Navigation and Mapping

When it comes to navigation, the Garmin Descent Mk2 & Mk2i have some of the best capabilities for mapping and GPS tracking. The GPS functionality is great for noting entry and exit points, which can come in handy when diving in unfamiliar waters or traveling to new locations. There is also an optional APNEA feature that allows you to take advantage of valuable data like depth, heart rate, and ascent time during freediving sessions.

The 4-inch display on the Descent Mk2i is one of its biggest selling points. It’s both easy to read above and below the surface—from 270×330 pixels resolution in air mode to 300×400 pixels resolution underwater. Additionally, the inch-long display plus photosensitive backlight make it easier to get a good light show when diving at night—and that’s key for your dive buddy!

Now that we've given you a full overview of the Garmin Descent Mk2 & Mk2i, it's time to look at the pros and cons of these two watches.

First, let's talk about the positives: The Descent MK2 includes pulse oximetry - a major plus for fitness users, who can now measure blood oxygen levels during workouts. It also has an extensive array of capabilities, including dive metrics and navigation. Plus, its display is bigger and clearer than previous editions, so it's easier on the eyes.

On the other hand, there are some negatives to consider. For one thing, it's expensive compared to some other dive watches; depending on where you buy it from, you could be looking at spending up to $1,000 or more. Additionally, it doesn't offer all of the features that land or water-based fitness watches have; if you're looking for something to replace your existing fitness watch (or if your needs go beyond what a dive watch can offer), then this might not be the best choice for you.

Overall though, the Garmin Descent Mk2 & Mk2i have a lot to offer when it comes to dive watches and is definitely worth considering if you're in the market for one.


All told, the Garmin Descent Mk2 is a powerful and versatile dive computer that’s well-suited for both recreational and technical divers. It has a ton of features and is easy to use, making it a great option for anyone looking for an advanced dive computer.

The Garmin Descent Mk2i is even better, with its added mapping capabilities making it perfect for divers who want to explore new dive sites. It’s also worth noting that the Mk2i is backward compatible with Mk2 dive gear, making it a great option for those who already own a Descent Mk2.

Whether you’re a recreational or technical diver, the Garmin Descent Mk2 and Mk2i are definitely worth considering. They’re some of the best dive computers on the market, and they’ll definitely help you take your diving to the next level.
