Best Garmin watch for freediving (2026)

What matters in a Garmin watch for freediving?

For freediving, the spec sheet matters less than three things it won't tell you:

• Whether Connect IQ can read true depth. Garmin's Connect IQ platform lets apps read the barometric sensor, but on some watches the firmware caps that reading at roughly 3 m. A capped reading is fine for timing your dives. It just can't run a depth-based surface-rest model.
• Case rating (depth alarm ceiling). The Fenix family is 10 ATM, rated to 40 m, and the app's depth alarms go that deep too. The Descent is rated for scuba to 100 m, and its depth alarms go to 120 m.
• Which app you want to run. inDepth Apnea Blue runs on every watch in this guide. inDepth Apnea Pool runs on all of them except the plain Fenix 5 / 5S / 5X, which don't have enough memory to launch it.

The cap on the Fenix 7, Descent Mk2 and Descent Mk3 comes from how Connect IQ works. The watch itself is fine. The Descent's own dive mode reads true depth from its dedicated deep sensor, but Connect IQ apps just don't get access to that sensor. For the Fenix 7, we're going by the cap we measured on a Mk3. We haven't dive-tested a Fenix 7 itself.

Best overall: Fenix 8

If you're buying new, the Fenix 8 is the best Garmin watch for freediving. It's a dive computer with a dedicated depth sensor rated to 40 m, its Connect IQ depth reading isn't capped, and it runs both inDepth Blue and inDepth Pool. That means you get every surface-rest model (2×, 3×, Adaptive (AIDA), Taravana, Molchanovs, Manual), and the same watch covers your dynamic apnea training in the pool too. It records the apnea sub-sport natively, but its depth alarms still top out at the 40 m case rating.

Best value: a used Fenix 5 Plus

The Fenix 5 Plus family (including the 5S Plus and 5X Plus) is the best value. Connect IQ reads true depth on them (uncapped, and checked in open water to 30 m), so every surface-rest model works, and they run inDepth Blue, inDepth Pool and inDepth Dry. They're a few generations old now, so used prices are low. For freediving, the depth reading is what counts, and newer models haven't improved on it.

The plain Fenix 5 / 5S / 5X are even cheaper and also read true depth. But they can't run inDepth Pool (there isn't enough memory to launch it), and the Fenix 5 and 5S can't mark spots in the app. If all you want is a depth computer for Blue, they're still a good buy.

Best for spearfishing and deep line diving: Descent Mk3

The Descent Mk3 is Garmin's dedicated dive watch. Its built-in dive mode is a full scuba computer rated to 100 m, and the app's depth alarms go to 120 m, way past the Fenix's 40 m. If you spearfish and also scuba dive, that case rating and the built-in dive mode are a big deal.

The catch for freediving with inDepth Blue is the Connect IQ cap. On the Mk3 (and the Mk2) you don't get the surface-rest models that need depth, because the capped reading can't run them. The 2×, 3× and Manual models still work. They go by dive time, which the watch measures accurately, so you still get a surface interval countdown. If you want the Taravana or Molchanovs models on your wrist, use a Fenix 5 Plus or Fenix 8 alongside the Descent for those depth sessions.

Is the Fenix 7 good for freediving?

The Fenix 7 is a great running and multisport watch, and both inDepth apps fully support it. For freediving, though, it's the odd one out. It doesn't have the Fenix 8's dedicated depth sensor, and its Connect IQ depth reading is capped at ~3 m like the Descent's, without the Descent's 100 m case rating or built-in dive mode. If you already have one, inDepth Blue runs on it with 2× / 3× / Manual surface rest. If you're buying a watch just for freediving, a used Fenix 5 Plus or a Fenix 8 will serve you better.
