Garmin Forerunner 405CX GPS-Enabled Sports Watch with USB ANT Stick & Heart Rate Monitor

The Garmin Forerunner 405CX is the evolution of GPS-enabled training. This sleek sport watch tracks your distance, pace and heart rate, then wirelessly sends the data to your PC for later analysis. The 405CX features heart rate-based calorie computation and comes with a second wrist band option suitable for smaller wrists.

NEW CALORIE COMPUTATION FEATURE
Using algorithms developed by exercise scientists and world-class athletes, the Garmin Forerunner 405CX monitors the micro changes in a user’s heart rate and uses that detailed information to better calculate the number of calories burned during aerobic activity. THIS IS THE MAIN DIFFERENCE BETWEEN THE 405 AND THE 405CX.

The new algorithm calculates your calories burned based on your individual heart rate data and adjusts for speed and distance data. As an example, the new algorithm would accurately report your calories burned while going downhill on a bike. Despite the increase in speed which would imply more work and therefore more calories burned, the watch tracks your heart rate and calculates that you are actually doing less work (which you are since gravity is helping you out). The team at Clever Training welcomes this new and improved algorithm as we were always surprised that we burned more calories going downhill than going uphill.

THE OTHER TWO DIFFERENCES ARE:

• Color: The 405CX is Blue/Gray while the 405 comes in Black and Green
• Straps: The 405CX includes a second strap for smaller wrists.

Watch the below video for instructions on how to change the straps out in the 405CX.



Watch Results

Loaded with serious training features, Forerunner 405CX continuously records your time, distance, pace, calories burned and heart rate. Each workout is stored in memory so you can review and analyze the data to see how you've improved. And advanced training features will challenge you to step up your pace — race against Forerunner's Virtual Partner to improve your times, or set up interval workouts without having to circle the track. You can even download recorded courses to compete against previous workouts. To use the watch, simply tap the touch bezel to change screens without fumbling for a button.

Track Heart Rate

Forerunner 405CX comes with a flexible, wireless heart rate monitor to help you make the most out of your training. The digital heart rate monitor continuously tracks heart beats per minute and uses your heart rate for advanced calorie computation, so you know how many calories you're burning. Train in a certain heart rate zone to improve your fitness level or compare your pace and heart rate to past performance on the same run.

Share Workouts Wirelessly

With Forerunner 405CX, you can share your locations, advanced workouts and courses wirelessly with other Forerunner 405 users. Send your favorite workout to your friends to try, or compete against someone else's recorded course. Sharing data is easy: just select "transfer" to send your information to a nearby device.

Run, Sync, Store and Share

Once you've logged the miles, innovative ANT+ wireless technology automatically transfers data to your computer when Forerunner is in range. No cables, no hookups. The data’s just there, ready for you to analyze, categorize and share through our online community, Garmin Connect or the optional Garmin Training Center software. You can even plan workouts on your computer and then send them to your Forerunner.

Train Year Round

Take your training inside with the versatile Forerunner 405CX and optional wireless accessories. Pair it with an optional foot pod to track your speed, distance and running cadence indoors when GPS signals are unavailable. The wireless foot pod clips onto your laces for easy removal and automatically turns on when you start moving. Or pair your Forerunner with an optional speed/cadence bike sensor to track the speed and distance of your cycling workouts.
