Inching closer to speedo accuracy
LOTS of people get in touch with Carsguide to complain about the accuracy of their car’s speedometer.
When you drive an old HiLux ute, as I do, you often wonder just how far from the mark the speedometer needle could be pointing.
Now I don’t have to wonder, or worry, after a $130 dive into the world of the web.
I’ve found a wireless digital speedometer that links to GPS to give me a continuous and accurate read on my speed.
The Mitsugawa speedo and I struck up a friendship when driving a new Mazda MX-5 in Scotland, where local rules mean the km/h calibrations on the speedometer had to be supplemented by an oldschool miles per hour reading.
In a country where metric millimetres are still overruled by historic inches, I found the compact Mitsugawa clear, accurate and easy to position. It can be charged from a 12V socket and has a powerful suction pad to fix it to the inside of the windscreen.
Back at home, an identical device allows me to check the accuracy of every test car’s speedo. It provides an instant head-up display, with greater clarity than lots of cars with tightly packed readings in a compact dial.
My stick-on speedo runs for 20-odd hours between USB plug-ins, is well lit for night driving and is a lot cheaper than a full-scale satnav that provides similar accuracy but with a much smaller speed readout.
