Whether you're training for a marathon or just looking to track your daily activity, make every minute count with the Garmin Forerunner 230. It packs a heap of technology to keep your fitness on point and analyze every detail of your daily activity and training bouts. The 230 tracks your distance, pace, and time out on the road, metrics that can be further supplemented with heart rate and estimated VO2 Max when paired with a compatible heart rate monitor strap sold separately. For daily life, this watch tracks steps, distance, calories, and sleep to accurately assess your non exercise time. The housing and crystal clear face conceal a GPS and GLONASS antenna, which is the basis for all the activity tracking capabilities of the Forerunner 230. It can tell you how fast you're going, how far you've gone, whether you're on pace, how fast your heart's beating, how many calories you've burned, how much elevation you've gained, how soundly you're sleeping, and host of other metrics. It even provides custom, goal oriented workouts that are downloadable with Garmin Connect. For indoor sessions, the 230's built in accelerometer accurately captures distance and pace on the treadmill no need for bulky foot pods. Once the Forerunner 230 has tracked all of these things, it can save them or automatically share them with Garmin Connect so you can see what you've done, the progress you've made, and start planning for the future. Among other things, it's compatible with ANT, which lets your tracking devices talk to each other and share even more data. The 230 boasts a water resistance rating of 5 ATM to withstand the forces of up to 50 meters of water and comes packaged with a chargingdata clip and user manual.
