TrackMan 3e & 4 are capable of connecting wireless to device (PC, Laptop, iOS). We use a wifi connection versus Bluetooth as it is a much more secure connection. Even though the devices are connected using wifi there is no internet connection involved. When connected there will be a message saying "no internet connection secured," when you see this message you have connected to the TrackMan and can open software.
Below is the process of how to connect:
Connect to the Radar with PC or iOS Wi-Fi
Select your radar on the available Wi-Fi connections (its default name is your serial number)
Start TPS (PC) or TrackMan app (iOS)
Click Shot Analysis (PC) or Start (iOS)
Select Target · Select Player
For custom clubs, select Club Type
