Garmin Forerunner 965 vs Garmin Instinct 2
The Verdict
Garmin Forerunner 965 and Instinct 2 serve different runner profiles at notably different price points. The Forerunner 965 dominates with its 1.4-inch AMOLED display at 454 x 454 resolution, offering vibrant color maps and workout metrics that serious runners appreciate, plus NFC for contactless payments and WiFi connectivity. Battery life matches between the two in smartwatch mode (23-24 days), though the Forerunner edges out slightly with 31 hours GPS versus the Instinct's 30 hours. Health tracking differs meaningfully: Forerunner 965 includes skin temperature monitoring while Instinct 2 lacks this feature, but both offer SpO2 and heart rate tracking without ECG. The Instinct 2 compensates with military-grade durability (MIL-STD-810) and optional solar charging that extends battery indefinitely in smartwatch mode, making it genuinely rugged. Weighing the trade-offs, the Forerunner 965's superior display and connectivity justify $250 extra for runners wanting advanced training insights and color visualization. The Instinct 2 remains excellent value for minimalist runners or those prioritizing durability and minimal charging cycles. Forerunner 965 wins for serious athletes; Instinct 2 for budget-conscious or ultralight adventurers.
