Hammerhead Karoo 1 Professional Bike Computer.
Powerful, intuitive to use, has a fantastic screen and decent battery life.
The Karoo has probably the best screen of any bike computer – 640×480, 229 pixels per inch. The Gorilla Glass top layer of the screen has a semi-matt coating that does a really good job of reducing reflections from the sky and things passing overhead. IP67 waterproofing: the screen is never affected by raindrops hitting it.
ATN+, Bluetooth, Wi-Fi connection, plus – 3G sim-card slot.
Used, in good condition.
