Overview: The Garmin Forerunner 45S is a lightweight, stylish running watch with a high-sensitivity GPS receiver which accurately records the distance, time, speed, and location of your runs. You can also use it to simply count your steps during an activity or throughout the day. The watch has the Elevate™ built-in wrist heart rate monitor which helps you meet your health goals. The device keeps track of your personal records, and lets you know when you have set new ones. The Forerunner 45S provides constant feedback, including the distance traveled, elapsed time, pace, lap time, speed, and your heart rate. After your run, you can upload your results to the Garmin Connect online community.
Versions: The Garmin Forerunner 45S comes with a 39mm (1.55") diameter case, and is available with White or Iris bands. It fits wrists with a circumference of 4-7/8" to 7-1/4" (124mm to 185mm). A larger version, the Forerunner 45, comes with a 42mm (1.65") diameter case and a choice of Black or Lava Red bands. The Forerunner 45 fits wrists with a circumference of 5" to 7-3/4" (129-197mm).
Water Resistant: The Forerunner 45S has a 5 ATM water rating, which means it is resistant to moderate moisture contact. Not only can you run in the rain and wet weather, you can even swim or shower while wearing the device. The device also has a wide operating temperature range of -4° to 140°F.
LCD Screen: The Forerunner 45S features a 1.04" diameter LCD screen with a resolution of 208 x 208 pixels. The display has a backlight timer that can be set to 8 sec, 15 sec, 30 sec, or 1 minute.
High-Sensitivity GPS Receiver: The unit features a high-sensitivity GPS receiver which will stay locked onto satellites, even near tall buildings or under tree cover. By default, the devices uses the U.S. Global Positioning System (GPS) to locate overhead satellites. When you're in locations with poor sky visibility, you can use a combination of GPS and GLONASS (Russian satellite system), or GPS and Galileo (European Union satellite system) to obtain a more accurate position. Using GPS and another satellite system together will reduce battery life more quickly than using GPS alone.
Rechargeable Battery: The Forerunner 45S has a built-in Lithium-Ion rechargeable battery, which will give you up to 13 hours battery life in GPS mode. When not using GPS, the device has a battery life of up to 7 days in watch mode with smart notifications, activity tracking, and wrist heart rate. A 21" data/charging cradle is provided for charging the battery and uploading your training data. It takes approximately 2 hours to fully charge a depleted battery.
Add-on Sensors: The Forerunner 45S can be used with wireless 2.4 GHz ANT+ add-on sensors, such as the optional chest-worn Heart Rate Monitor, Foot Pod, Bike Speed, or Cadence Sensor.
User Profile: The Garmin Forerunner 45S uses information that you enter about yourself to calculate accurate training data. You can modify the following user profile information: Maximum Heart Rate, Gender, Birth Year, Height, and Weight.
Move Alert: Sitting for prolonged periods of time can be harmful to your health. You can set the Forerunner 45S to simply remind you to move. The Move Alert is a timer that is triggered after one hour of inactivity. When the alert is triggered, the move alert is reset only after a couple of minutes of continuous activity, such as a short walk.
Health Stats Widget: The Health Stats widget gives you instant feedback on your health data. At a glance, you receive your current heart rate, stress level, and Body Battery Level. The stress level is the result of a 3-minute test performed while standing still. The Forerunner measures your heart rate variability to determine your overall stress, expressed within a range of 1 (Low) to 100 (High). If your stress level is high, you'll be prompted to start a relaxation activity. The Body Battery level is like a gas gauge for your car, indicating the amount of your available reserve energy. The device analyzes your heart rate variability, stress level, sleep quality, and activity data to determine your overall Body Battery level. Your level is expressed in a range between 0 and 100, with low (0-25), medium (26-50), high (51-75), and very high (76-100) reserve energy designations. In addition, you can view your heart rate, stress level, or Body Battery level over a specific period, if desired.
Heart Rate Alerts: When using an optional chest-worn Heart Rate Monitor or the built-in wrist-based HRM, you can set the Forerunner 45S to alert you when your heart rate is above or below a target zone or a custom range. Each time you exceed or drop below the specified range or custom value, a message appears on the display. The device will also beep if audible alerts are engaged.
Auto Lap: Auto Lap automatically marks a lap after every mile. This feature is helpful for comparing your performance over different parts of an activity. Each time you complete a lap, the device will beep or vibrate, and the lap time is displayed.
Auto Pause: You can set the Forerunner 45S to pause the timer automatically when you stop moving, or when your pace drops below a specified value. This feature is helpful if you have to stop for traffic or to tie your shoe during your run.
Sleep Tracking: If you wear the Forerunner 45S while you are sleeping, the device automatically measures your sleep time and your movements. Sleep statistics include: total hours of sleep, sleep levels, and sleep movement. Your sleep statistics can be uploaded and viewed on your Garmin Connect account.
Garmin Connect: After you complete and save an activity to the Forerunner 45S, you can upload the data to Garmin Connect, the online tool for tracking, analyzing, and sharing your health and fitness activities. You can view the results of each activity, along with detailed analysis of your progress. Garmin Connect compiles your weekly, monthly, and yearly averages of your activities and health stats, and earn badges for meeting your goals or other accomplishments. You can also connect with your friends and share your results, or even compete with them in like activities. Garmin Connect is compatible with iOS (requires version 11.0 or later) and Android devices (version varies with device).
