Sick of roaming the neighbourhood late at night screaming ‘Fido!’ at the top of your voice? Fret no more – not with a cool new gadget called the Pet Tracking System on the market.
The PTS pet collar is a new revolutionary way to find a pet through the use of 4 satellite systems and a simple SMS/GMS message.
So how does it work? When Fido doesn’t return after his evening leak, you simply call the telephone number of the particular pet collar. The satellite antenna on top of the collar then zones in on any number of signals from at least 4 satellites and the collar sends the location of your lost pet back to you using the GSM and SMS network on your phone. It's precise within 15 meters of the lost pet - even across continents!
