The Karoo 2 GPS Bike Computer by Hammerhead - Android-based navigation

The Karoo 2 GPS Bike Computer from Hammerhead impresses with an aerodynamic profile, Android-based software and a high level of user-friendliness. It is operated via the touch screen made of matt, scratch-resistant Dragontail™ glass or four separate buttons on the sides of the unit. The 3.2" display offers you a quick overview of the route and has an enormously high resolution. You can follow route guidance completely seamlessly. If you take a wrong turn, the re-routing function will guide you back to your planned route. Even without a pre-planned route, the Karoo 2 reliably records your kilometres. If necessary, you can be guided home via the " Home" function. Performance data is recorded via linked sensors, which you can always have in view. It is also possible to connect to your mobile internet provider via a separate SIM card, which allows you to upload new tours onto the GPS device. If you like to ride competitively, you will benefit from the integrated Strava Live segments. Personal records, QOMs and KOMs are only a matter of time!

The upcoming Hammerhead brand has already made its mark in the World Tour scene. For the 2021 season, Team Israel Startup Nation has staked their reliance on the Karoo 2.

Purchased from Hammerhead before it was available here. Incredible navigation and lighting fast adjustments and response. Head and shoulder above the Garmin 1030 for me in everything but battery life, which for me lasts 10 hours at 40% brightness with one ANT+ and one Bluetooth connection (50% is equivalent to 100% on Garmin). Incredible customer support and constant improvements. This company is the future for bike head units.

Отличный аппарат, денег своих стоит однозначно!
Прост и удобен, никаких танцев с бубном при закачке треков. Приятный, небликующий экран, да и вообще интуитивная простота это его второе имя.
P/s Беркут Егор, твой обзор на ютубе определил мой выбор, долголетия тебе )

Much more better user experience than my old Garmin Edge 830. New features added every month. Battery life with always powered on display around 10-12 hours in temperatures slight below zero. Android OS giving possibilities to install third-party apps with .apk.

Already really good (and by far the best for nav and live segments), but more than that, constantly evolving through software updates. Very happy with my purchase straight from Hammerhead, cool to see it show up in stores as well!
