Wireless Sensors

Your watch can be paired and used with wireless sensors using ANT‍+® or Bluetooth® technology (Pairing Your Wireless Sensors). After the devices are paired, you can customize the optional data fields (Customizing the Data Screens). If your watch was packaged with a sensor, they are already paired.

For information about specific Garmin® sensor compatibility, purchasing, or to view the owner's manual, go to buy.garmin.com for that sensor.

Description

Club Sensors

You can use Approach® CT10 golf club sensors to automatically track your golf shots, including location, distance, and club type.

Heart Rate

You can use an external sensor, such as the HRM 200, HRM 600, HRM‍-Fit™, or HRM-Pro™ series heart rate monitor, to view heart rate data during your activities. Some heart rate monitors can also store data or provide advanced running data (Running Dynamics) (Running Power).

Foot Pod

You can use a foot pod to record pace and distance instead of using GPS when you are training indoors or when your GPS signal is weak.

Headphones

You can use Bluetooth headphones to listen to music loaded onto your Venu 4 watch (Connecting Bluetooth Headphones).

inReach

The inReach® remote function allows you to control your inReach satellite communicator using your Venu 4 watch (Using the inReach Remote).

Lights

You can use Varia™ smart bike lights to improve situational awareness. With a Varia headlight camera, you can also take photos and record video during a ride (Using the Varia Camera Controls).

Power

You can use the Rally™ or Vector™ power meter bike pedals to view your power data on your watch. You can adjust your power zones to match your goals and abilities (Setting Your Power Zones), or use range alerts to be notified when you reach a specified power zone (Setting an Alert).

Radar

You can use a Varia rearview bike radar to improve situational awareness and send alerts about approaching vehicles. With a Varia radar camera tail light, you can also take photos and record video during a ride (Using the Varia Camera Controls).

RD Pod

You can use a Running Dynamics Pod to record running dynamics data and view it on your watch (Running Dynamics).

Shifting

You can use electronic shifters to display shifting information during a ride. The Venu 4 watch displays current adjustment values when the sensor is in adjustment mode.

Shimano Di2

You can use Shimano® Di2™ electronic shifters to display shifting information during a ride. The Venu 4 watch displays current adjustment values when the sensor is in adjustment mode.

Smart Trainer

You can use your watch with an indoor bike smart trainer to simulate resistance while following a course, ride, or workout (Using an Indoor Trainer).

Speed/Cadence

You can attach speed or cadence sensors to your bike and view the data during your ride. If necessary, you can manually enter your wheel circumference (Wheel Size and Circumference).

You can also attach speed or cadence sensors to your wheelchair and view the data during your activity. When the sensor is attached, your watch creates and saves an activity to your Garmin Connect™ account each time you push your chair.

tempe

You can attach the tempe™ temperature sensor to a secure strap or loop where it is exposed to ambient air, so it provides a consistent source of accurate temperature data.
