Overall

Although the 745 and 945 share many features, when comparing the Garmin Forerunner 745 vs. 945, the 945 is the clear winner. 

 

The 945 offers double the battery life, topographical map functions and has twice as much music space. It’s also a larger watch for easier viewing of the screen.

 

That being said, the 745 is newly released and is a strong contender, especially for people looking for a more economical option and daily workout suggestions.

Stand Out Features

Now that we’ve taken a look at Garmin 945 vs. 745 features regarding their similarities, let’s take a look at where they diverge. 

 

  • Battery life: The 945 lasts for an incredible 14 days on smartwatch mode, whereas the 745 lasts for seven days. When it comes to GPS mode without music, the 945 lasts up to 36 hours and the 745 up to 16 hours.
  • Topographical maps: Hike, run, or bike knowing you’ll be guided with the 945’s colorful onboard maps. They can be used in the city, but this feature is ideal for trail hikes and runs. The 945 also offers ClimbPro maps to map your current and upcoming climbs as well as turn-by-turn navigation and suggested routes with round-trip routing.
  • Golf mode: Triathlete golfers will love that the 945 comes with 40,000+ preloaded golf maps. 
  • Workout suggestions: The 745 offers daily workout suggestions based on your training load and status. Workout suggestions is a key difference from the 945, which doesn’t offer this feature.
  • Price: The 945 costs $100 more than the 745. Is it worth it? We think so. But it’s important to analyze your own fitness smartwatch needs and budget to determine which watch is best for you.

 

Long story short? When comparing the differences between the Garmin Forerunner 945 vs. 745, the 945 excels in areas that are important to most athletes.

 

However, the 745 is a reliable option for athletes looking for a more economical option. It’s smaller and equipped with exercise and health stats, making it a good contender among fitness watches.
