WanderSearch Canterbury can provide two types of devices, one which operates on radio frequency and the other is a GPS watch for children. The radio frequency device (Wandatrak) has a battery which lasts for 6 months and is showerproof. This means that clients can wear it all the time. With the Wandatrak device, if the person goes missing then Search & Rescue are notified and track the missing person with specialist equipment. With a GPS device the caregiver is able to monitor where the person is either on their phone or computer.
