Summary of Differences
- Topographical Maps – The Forerunner 945 includes full-color onboard maps to guide you on your run, hike or mountain biking session. This tech is usually reserved for the Fenix and Marq range, but it sits very well in the FR945. It is particularly valuable for trail runners, but it’s also great for city running.
- Golf Mode – The Forerunner 945 is basically a triathlon watch that doubles as a dedicated golf watch. You get almost all the golf features that you can access in the Garmin Approach S60 (premium Garmin golf watch).
- Additional Music Storage – The Forerunner 745 can store up to 500 songs. The Forerunner 945 can store up to 1000 songs. The extra space should come in handy if you’re passionate about training with music.
- Better Battery Life: The battery life of the FR945 is twice as long as the battery life of the FR745. This applies to smartwatch mode, standard GPS battery life and GPS + music mode.
- Daily Workout Suggestions: Only the FR745 gives you daily workout suggestions (at this point in time). These are run and ride recommendations based on your current training load and training status
- Price – The recommended selling price of the FR745 is $100 cheaper than the RSP of the FR945. If you don’t play golf and you’re not into trail running, it should be pretty safe to just opt for the cheaper unit (FR745).
