Garmin has introduced the Enduro 4 at $899, updating the ultra-endurance GPS watch with doubled 64GB onboard storage, a faster processor, 50% more RAM, and a new ComfortFit band. In initial testing by DC Rainmaker, the upgraded internals delivered faster on-device route calculations and smoother map rendering, while the 51mm chassis, 1.4-inch MIP solar display, and battery specs remain unchanged from the Enduro 3. The reviewer concludes that the Enduro 4 is primarily a compelling upgrade for Enduro 1 and 2 users, noting that existing Enduro 3 owners will receive most new software metrics in future updates.
