I have a couple bikes with wired computers, very reliable and very accurate. My wireless computers do not automatically start when I start rolling and they go through batteries faster with less accuracy.
I often use a GPS too, but not always. Even when I use a GPS, the wired computer is more accurate so if I am tracking distance for some purpose, the computer is the distance I use.
My wired computers are from a company that went out of business a few years ago, so unlikely you would be able to get the same ones I have, Sports Instruments was the brand.
