Good BC, would buy it again.

- Dennis 28 September 2025

I'm happy with the Karoo 3, unfortunately it's not possible to pair a smartwatch as a heart rate monitor these days.

- Stefan 27 September 2025

Fast alles ist selbsterklärend, einfach einzustellen. Sehr übersichtlich, keine umständliche Menüführung wie bei anderen Herstellern.

Any time again

- Wilhelm 13 September 2025

The bike sat nav works perfectly, handling the device is a bit time-consuming at first. But it works perfectly and that is the most important thing...

Absolutely recommended

- Peter 30 August 2025

I bought the Hammerhead Karoo (3) as a successor to the Karoo 2. And for a very competitive price at Mantel. In my eyes, the Karoo 2 was already a very fine bike navigation, and the Karoo (3) has improved on many fronts: Clear and brilliant display Clearer feel when pressing the buttons Separate power button Battery life Seal usb connector does not come loose Absolutely recommended as far as I'm concerned.

Pros & Cons

Comprehensive yet easy to use
Great mounting system
Very bright screen
Very good offline maps

Absolute top class at a top price - Karoo 3

- Marco 26 August 2025

Coming from the Wahoo Roam v1, the Karoo 3 is a game changer for me. The entire handling is sensational and easy, even while riding. And the price is unbeatable for what the Karoo 3 offers. I can highly recommend the Karoo 3.
