What Customers Say

People enjoyed the Instinct 3's rugged feel, weeks‑long battery life and bright AMOLED display, with some praising the built‑in LED flashlight and detailed sleep and recovery insights. At the same time, it was noted to be lacking the absence of offline maps or music, and a few lamented that Garmin still reserves some sensors and smaller case sizes for pricier models. Wearers say the multi‑band GPS and durable case make it ideal for outdoor sports, yet they point out that its size and limited smart functionality mean it's not for everyone. Overall it's considered a capable adventure watch with a modern screen, albeit missing some premium features.
