Garmin Instinct 3 Solar: Who is it right for?

(Dan Tri Newspaper) - The Garmin Instinct 3 Solar continues to inherit the robust and durable design characteristic of the Instinct series, while also offering some notable improvements. However, the watch still has some drawbacks.

Advantages: Reliable GPS, long-lasting battery, especially suitable for outdoor enthusiasts and extreme sports lovers.

Disadvantages: Monochrome screen, large frame, unsuitable for people with small wrist circumference, menu system and UI/UX are not user-friendly.

Editor's advice: If you are an outdoor enthusiast and enjoy extreme sports, the Garmin Instinct 3 Solar is suitable. However, if you have a small wrist and use it daily for health tracking and office fashion , this watch may not be the best fit.

Design and materials

As the latest model in the Garmin family, the Instinct 3 Solar features a reinforced polymer casing combined with a metal bezel, resulting in high durability and excellent impact resistance.

This design meets the MIL-STD-810 military standard for heat resistance, shock resistance, and water resistance, allowing it to operate reliably at depths up to 100 meters.

However, its large, bulky, and distinctly military design makes the watch easily out of place when paired with a shirt, suit, or in an office environment. This makes it less versatile for those seeking a multi-purpose device suitable for everything from the wilderness to the boardroom.

The Instinct 3 Solar features a 1.1-inch monochrome MIP display with a resolution of 176 x 176 pixels. This screen allows for clear visibility in direct sunlight. However, the display does not offer the same vibrant colors as the AMOLED screens on recently released models such as the Forerunner 965 or Fenix ​​8.

The lack of a color screen and detailed maps may be a limitation for some users. The user interface (UI/UX) remains highly technical and less intuitive, making it difficult for new users or those unfamiliar with technology to operate and access features.

Navigating between menus also takes some getting used to. However, for those who are already familiar with Garmin and have used previous Instinct models, this shouldn't be a major issue.

The watch connects to the Garmin Connect app very quickly, and all metrics can be viewed through the Garmin Connect app on your phone, or easily via the web.

However, the lack of a color screen can impact the training of beginners when monitoring heart rate zones or exercise status metrics like VO2MAX, and may not appeal to some users who desire a more vivid visual experience.

The Instinct 3 Solar comes in two versions: 45mm and 50mm. The model we tested has a 50mm diameter, yet it's very lightweight. The total weight is only 53 grams. The soft and flexible silicone strap fits various wrist sizes, ensuring comfortable wear for extended periods.

However, the watch face is too large (50mm), making it look disproportionate on wrists smaller than 16cm. The watch also lacks calling functionality found in higher-end models, only receiving notifications from smartphones. The relatively small screen size may also make reading information difficult for some users.

Other notable features for everyday use include: receiving smart notifications, controlling music on your phone, and notably, this watch series also supports Garmin Pay contactless payments, which is now available to Vietnamese users with VPBank accounts.

One highlight of the Instinct 3 Solar's design is the integrated flashlight with multiple brightness levels and a red light, useful in low-light conditions. This feature, previously only found on high-end watches like Fenix, is now included for the first time on this model.

Features and performance

The heart of the Instinct 3 Solar is the 4th generation Garmin Elevate wrist heart rate sensor. This sensor is also found in many other high-end models such as the Garmin Fenix ​​7 Series, Garmin Forerunner 955, 965, Garmin Fenix ​​7, Epix Gen 2, etc., allowing users to measure heart rate 24/7, measure Pulse Ox (blood oxygen saturation), track heart rate variability (HRV), monitor breathing rate, VO2MAX, and more.

These are important metrics that the sports training community pays the most attention to and spends the most time analyzing. By evaluating these metrics, users can learn about their training capacity, readiness level, potential energy, and many other personal indicators.

Additionally, the Instinct 3 Solar measures altitude, atmospheric pressure, compass, and temperature. The watch supports multi-band GPS positioning with SatIQ technology, providing high accuracy. These are significant advantages for mountaineers, explorers, and those who enjoy adventurous activities.

Another highlight of the Instinct 3 Solar is its battery life and solar charging capabilities. As the name "solar" suggests, thanks to solar charging technology, the watch can achieve impressive battery life.

According to Garmin, the watch can operate indefinitely in smartwatch mode when exposed to sufficiently strong sunlight (assuming it's worn all day for 3 hours a day under 50,000 lux conditions). However, in real-world conditions, battery life may vary depending on usage and lighting conditions.

Experience using Garmin Instinct 3 for mountain climbing.

The test group used Garmin Instinct 3 to climb a mountain for 5 hours, covering a distance of approximately 17 km with a cumulative elevation gain of 1,500 meters. This trail was located in the Dong Do forest (Soc Son, Hanoi), with quite challenging and diverse terrain.

To assess accuracy, we used an additional high-end watch as a reference for the parameters.

From the moment of departure, the multi-band GPS feature with SatIQ technology on the Instinct 3 Solar proved its accuracy. The watch quickly determined its location and maintained a stable connection even when moving through dense forest areas.

This allows the team to accurately track the distance traveled and current altitude, which is quite helpful for navigation on complex trails.

In reality, compared to higher-end Garmin models, the discrepancies in specifications are not significant. The GPS works accurately even though most of the route involves traveling through foliage and bushes.

One point to note is that when climbing steep slopes with walking sticks, the user's wrist, when bent, can easily accidentally press the button, potentially causing the watch to enter unwanted commands. Users should loosen the strap to avoid this.

Additionally, due to its monochrome screen design, the Garmin Instinct 3 lacks detailed maps. The watch does not support displaying color and detailed maps like some other Garmin models, which may cause minor difficulties in locating positions on routes you're experiencing for the first time.

Throughout the journey, despite continuous use of GPS and activity tracking features, the watch's battery remained at a high level. The solar charging technology worked efficiently, especially when moving in direct sunlight, helping to extend usage time. Over a total of 5 hours of continuous use, the watch only consumed about 10% of its energy.

The wrist heart rate sensor operates reliably, providing real-time heart rate data. This is very helpful for users when climbing hills, allowing them to regulate their heart rate to zone 2 or zone 3, helping to maintain endurance and prevent overexertion, especially useful when climbing steep slopes.

Real-world experience shows that the Garmin Instinct 3 Solar is a reliable companion for outdoor enthusiasts. Its durable design, impressive battery life, and accurate health tracking and positioning features give users the confidence to conquer the challenges ahead.

Conclude

The Garmin Instinct 3 Solar is a reliable watch for outdoor enthusiasts, from trekking and mountaineering to exploring challenging terrain. Its advantages include a military-grade, ultra-durable design, accurate multi-band GPS, and virtually unlimited battery life in sunlight.

However, the Instinct 3 Solar isn't for everyone. Its bulky design, monochrome screen, and digital interface make it less appealing to a select group of users, especially those needing a "multipurpose" watch: for work, exercise, calls, and daily health tracking.
