I have the Sensatyre multi unit with the under vehicle remote aerial and it works very
well, has picked up all five tyres (rear mounted spare) before the truck has been backed out of the shed.
Is also easy to reprogramme on the go when you change
tyre pressures for different road conditions, reacts every time when dropping
tyre pressures and best of all has saved two tyres in twelve months so from now on it has paid for itself.
