The Enduro line keeps getting better. This Garmin Enduro 3 brings many improvements over the previous generation. 

• Battery life - get into the power management modes to unlock 100+ hours of super accurate GPS mode.
• Flashlight - still there, still bright
• Crisper display - not nearly as bright at AMOLED, but it's a tiny bit better after removing the solar overlay.
• Better solar - new solar ring for extending battery life that much further
• New buttons - more durable
