Your V2 can be charged from any USB port or USB compliant wall charger. Please use the micro-USB cable provided as this is specific to the design of the watch.
The watch screen will show that the device is connected and the percentage of battery its currently holding.
When you first receive your Shot Scope, we recommend charging fully before your first round. Please allow up to five hours for the watch to fully charge.
The battery life is approximately 5-6 hours, although this will change dependent on which mode the watch is being used in.
The tags for your clubs are completely passive and do not include a battery. There is no need for them to be removed or charged.
