Descent G2 Scuba Diving Computer Review: Uses Recycled Ocean-Bound Plastics for the Housing and Bezel

What the Descent G2 Is, and Who For

Garmin Descent G2 46mm Paloma tracks diving data and provides a 10 ATM dive rating for recreational and technical divers.

Using a device with multi-GNSS support allows for surface entry and exit point marking, providing a clear breadcrumb trail for your underwater excursions. This feature helps you identify exactly where you began and ended your dive without manual notes.

The Descent G2 facilitates this navigation by combining multi-GNSS support with a 1.2 AMOLED display for clear visibility. It provides the data needed to track these points accurately on the wrist.

We evaluated 15 scuba diving computers and selected the Descent G2 for this full review because it has 107 buyer ratings, the 10th most of the 15 screened. This review is for recreational and technical divers who need a reliable underwater computer. Our review is based on a research-based comparison of listing data.

The Short Answer on the Descent G2

Best for: you need a versatile scuba diving computer that supports multiple dive types including technical and freediving.

The Descent G2 is a capable choice at $489.99.

• Pro: The 1.2 AMOLED display provides clear visibility for underwater data.
• Pro: Sapphire lens construction provides high surface hardness against scratches.
• Pro: It supports five distinct dive types, including pool apnea and freediving.
• Con: The 46mm case diameter is larger than some compact dive watches, which may affect maneuverability for smaller wrists.

Don’t buy this if: you require a device rated for depths exceeding 100 meters.

Price assessment: The $489.99 price point is fair for a multi-GNSS supported device with sapphire glass and a high-resolution AMOLED screen.

The Numbers on the Spec Sheet

The Case Diameter is 46mm, which measures the width across the outer housing.

Before You Buy: Scuba Diving Computer Checklist

The first thing to check is whether your wrist size accommodates a 46mm case diameter to ensure the unit sits correctly on your arm.

• ☐ Confirm your wrist can fit a 46mm case diameter—otherwise, the housing may sit too wide or overlap your hand.
• ☐ Verify the 10 ATM dive rating meets your depth requirements—this rating limits the pressure depth the unit can withstand.
• ☐ Check that the 1.2 AMOLED display provides sufficient clarity for your visibility needs—lower resolution screens can make small text harder to read underwater.
• ☐ Budget for the $489.99 price point—failure to account for this cost will result in a budget mismatch at checkout.
• ☐ Ensure you have a compatible smartphone for the Garmin Dive app—without a compatible phone, you cannot sync your dive logs wirelessly.

You should not buy this scuba diving computer if you require a specialized freediving-only interface, as this unit is designed for multi-discipline use including recreational and technical diving.

Syncing your previous dives and stats to your phone is handled through the Garmin Dive smartphone app compatibility. You can view your logs on your phone by pairing the device with the app, which provides a digital record of your underwater activity. While the unit features on-device dive log storage to keep data safe during a dive, the app serves as the primary interface for long-term data management and viewing.

How this Scuba Diving Computer performs in practical terms

AMOLED Display and Sapphire Lens

The Garmin Descent G2 features a 1.2 AMOLED display, a type of screen that uses self-lit pixels to provide high contrast and vibrant colors in various lighting conditions. This display provides the clarity needed to read dive data quickly while submerged or in low-light environments. The sapphire lens provides a hard surface that resists scratches during heavy use, ensuring the screen remains clear throughout the life of the device.

Descent G2 provides the visual output for a variety of diving styles, including recreational, advanced, technical, freediving, and pool apnea diving. Because the 1.2 AMOLED display is the primary interface for all these modes, it ensures that complex data points remain legible during high-intensity tasks. The sapphire lens is the physical protection that allows the display to maintain its integrity against the abrasive elements of the underwater environment.

Multi-GNSS support and dive readiness for this underwater computer

The Descent G2 supports multi-GNSS, which allows the device to connect to multiple global navigation satellite systems simultaneously for more accurate positioning. This capability provides the surface entry and exit point marking that helps you track your location relative to your starting point. Dive readiness, a feature that calculates your readiness based on sleep, stress, recent exercise, and dives, provides a data-driven overview of your recovery status before you enter the water.

Multi-GNSS works like a GPS with multiple scouts looking for the same signal at once, ensuring you stay oriented even in challenging environments. The dive readiness feature helps you decide when to head out by synthesizing your physical recovery data into a single score. These features work together to provide a more complete picture of your dive preparation and location history than basic satellite tracking alone.

Recycled ocean-bound plastics provide the structural framework for this device

The housing, bezel, and buttons on the Garmin Descent G2 are made from 100% recycled ocean-bound plastics. This material choice provides the structural framework for the device while utilizing waste collected from marine environments. By using these specific materials, the device meets a standard for environmental impact without sacrificing the physical integrity of the watch-style dive computer.

The use of 100% recycled ocean-bound plastics provides a way to reduce the environmental footprint of your gear. Because these materials make up the housing and bezel, they form the primary exterior of the device that interacts with the water and your wrist. This construction choice allows you to use a durable tool that is built from repurposed waste.

Where the Descent G2 Sits Among the Alternatives

The Descent G2 offers a 46mm case diameter, providing a more compact form factor than the 55mm Shearwater Research Teric Color Wrist Dive Computer.

What the Price Buys

At this price point, you gain advanced metrics like VO2 max training and a dive readiness feature based on sleep, stress, and recent exercise, which are typically absent from basic entry-level units. You trade off a lower price for a device that supports recreational, advanced, technical, freediving, and pool apnea diving, providing a wider range of functional modes than a basic model.

This scuba diving computer is the right buy for you if you require multi-GNSS support and on-device dive log storage for $489.99. You might use this for a technical dive in a remote reef system where you need to mark surface entry and exit points and track your progress without relying on a tethered device.

What It Takes to Run the Descent G2

Setting up the Descent G2

You must have a compatible charging cable to provide power before the Descent G2 can be used for any underwater operations.

1. Unpack the Descent G2 and any included accessories.
2. Connect the device to a power source using a compatible charging cable to replenish the internal power source.
3. Sync the watch with the Garmin Dive smartphone app to manage your dive logs.
4. Verify the 10 ATM dive rating is active by checking the device’s internal status before entering the water.

Warranty and support verification

Warranty coverage and return policies differ by seller and country.

• Confirm the 10 ATM dive rating is intact by checking for housing cracks, as a compromised seal is not user-serviceable.
• Verify the sapphire lens is free of deep scratches that could affect visibility during a dive.
• Check that the leakproof buttons click freely to ensure they remain functional under pressure.

Perform a full power cycle and check the dive log sync on the first day of arrival while the return window remains open.

Questions Buyers Ask About This Underwater Computer

Dive Readiness and Sleep Tracking

The Dive Readiness feature calculates a score by analyzing sleep, stress, and recent exercise data to determine your recovery state. Because the data is not stated for specific sleep metrics, the Descent G2 uses these personal health markers to provide a readiness status before you begin a dive.
