Affordable Garmin Forerunner 45: A Budget‑Friendly GPS Smartwatch Review
The most budget‑friendly Garmin smartwatch that still delivers reliable GPS, continuous heart‑rate monitoring, step counting, and smart notifications is the **Garmin Forerunner 45**, priced under $100 in many promotions and perfectly suited for cost‑conscious fitness enthusiasts.

Why This Garmin Watch Made Headlines
Android Police recently highlighted the Forerunner 45 as “the Garmin to go if you don’t want to break the bank” [source].

Core Features of the Budget Garmin Model

Garmin’s Elevate™ optical sensor provides continuous heart‑rate data, alerting you when you exceed your target zones. The data syncs automatically to the Garmin Connect app for deeper analysis.

Smartphone Notifications
