Garmin Descent MK4i Leaks: Everything We Know So Far

The Garmin Descent series has always been a favorite among divers. These dive watches combine the ruggedness of a dive computer with the smart features we expect from a modern smartwatch.

Following Garmin’s pattern, a new Descent model is likely on the horizon after the Garmin Descent G2 release.

So, what can we expect from the Garmin Descent MK4i? Let’s dive into the leaks, rumors, and expected upgrades.

Garmin Descent Mk4i Release Date

Garmin often releases Descent models after their Fenix flagships. For instance, the Descent MK3 followed the Fenix 7. This makes sense, as they share a lot of the same technology.

Garmin tends to update the Descent line every two to three years. We saw the MK1 in 2017, the MK2 in 2020, and the MK3 in 2023.

If Garmin follows this pattern, the release date for the Garmin Descent MK4i is expected to be late 2025 or early 2026.

Will the MK4i be a minor update or a major overhaul? Only time will tell. However, Garmin has consistently refined its dive watches with each new release.

• MK1: Introduced basic dive features.
• MK2: Added advanced tracking and integration.
• MK3: Improved screen tech and connectivity.

If Garmin continues this trend, the MK4i could be the most impressive Descent yet.

Garmin Descent MK4i Display: Will It Feature AMOLED or MIP?

Will the Garmin Descent MK4i feature an AMOLED display or stick to the MIP screen? This is one of the biggest debates among divers

Garmin has been using AMOLED screens in more of its premium models, like the Fenix 8.

AMOLED screens offer some potential benefits for divers.

• Sharper colors make the display easier to read.
• Better readability in low light conditions would be helpful during early morning dives or deep underwater.

But there’s also a downside. AMOLED screens use more power than the MIP (memory-in-pixel) screens found in previous Descent models.

MIP screens are known for their efficiency, essential for battery life.

Will Garmin stick with MIP to maximize battery life, or will they switch to AMOLED for a better visual experience? It’s a tough choice.

If they go with AMOLED, Garmin must find ways to conserve power. Depending on the situation, they may introduce a smart power-saving mode or a hybrid display that switches between AMOLED and MIP. Divers rely on long-lasting watches, so battery life is crucial.

Build & Design: Titanium, Sapphire & Lightweight?  

Garmin often releases premium “Mark Edition” models with high-end materials like titanium and sapphire crystal. But are these materials really necessary for a dive computer?

The MK3i already had a solid build, with a titanium bezel and sapphire lens option. Garmin will likely refine the existing design rather than completely reinvent it.

Some divers have noted that the Descent series can be heavy. A more compact, lightweight design would be a welcome change. This would make the watch more comfortable for everyday wear and deep dives.

Of course, durability is essential for any dive watch. It needs to withstand saltwater corrosion and the immense pressure of the deep sea.

Garmin has a good reputation for building tough devices. Still, any new materials or design tweaks must meet those standards.

Connectivity: Will the MK4i Get LTE & Air Integration?

The MK3i introduced subwave sonar technology for tank pressure monitoring, which was a great addition. What other connectivity features might we see in the MK4i?

Better integration with dive apps would be a plus. A more seamless experience between the Descent watch and other Garmin devices would also be appreciated.

Garmin has also been adding LTE capabilities to some of its smartwatches. Could the MK4i come with built-in LTE for emergency signaling, similar to what we’ve seen in the Garmin inReach lineup?

Imagine being able to send an emergency message directly from your dive watch. That would be a huge benefit, especially for solo divers or those exploring remote locations.

The Descent series has evolved into more than dive watches. They’re also powerful multisport and daily wear smartwatches.

Expanding smart features like voice control, music storage, or improved GPS navigation would appeal to an even broader audience.

Battery Life & Durability: What to Expect

For divers, battery life is non-negotiable. The Garmin Descent MK2i set high standards, lasting up to 80 hours in dive mode. But will the Garmin Descent MK4i battery life hold up—especially if it adopts an AMOLED display?

Garmin must optimize power efficiency through solar charging, improved battery management modes, or a hybrid display system.

Divers need long-lasting watches for extended dives and multi-day expeditions. Garmin must compensate with better power management features or improved solar charging capabilities if the battery life takes a hit.

Durability is just as important. Garmin’s dive watches must withstand extreme underwater conditions, rough handling, and pressure changes. Will we see upgraded materials, a stronger bezel, or better water resistance in the MK4i?

Software optimizations can also play a role in battery life. If Garmin enhances power efficiency through smarter background processes and dynamic display adjustments, it could ease concerns about power drain.

Advanced divers would also welcome the inclusion of more robust dive profiles and decompression tracking.

Cost-Friendly Options: A Descent for Everyone?

Garmin has a history of introducing cost-friendly models inspired by its premium lineups.

For example, the Descent G1 Solar was built on the Instinct 2 Solar platform, making it a more accessible dive watch for those who didn’t need all the high-end features of the MK2i.

Will the MK4i follow this pattern? We might see a high-end “Mark” style version and a more affordable model for everyday divers.

This would expand the reach of Garmin’s dive technology, giving more people access to their trusted features.

Competition and Conclusion: Is Garmin Still on Top?

Garmin isn’t the only player in the dive watch market. Companies like Suunto and Shearwater also offer capable dive computers with their strengths.

Garmin’s advantage has always been its balance between smartwatch features and dive capabilities. If Garmin doesn’t offer meaningful upgrades, some divers might look elsewhere.

However, if the MK4i introduces advanced features like AI-powered dive tracking, improved GPS accuracy, or seamless air integration, it could solidify its place as the top choice for divers.

Ultimately, Garmin must ensure its innovations are practical, not just gimmicks. The Garmin Descent MK4i is shaping up to be an exciting release. Will it be a bold step forward or a minor refinement? Only time will tell.
