Hammerhead Karoo 3

An excellent device that shines with a super display. The built-in rechargeable battery has a long service life and I think the price-performance ratio is unbeatable!

Great navigation that does its job instantly. GPS signal is found in no time and off you go! The crystal-clear screen is amazing. It is a pity that the accompanying app, which in itself works fine, has fewer options than I had expected. No overview of kilometres ridden in a period, number of rides per period, calories burned and so on. But apart from that, nothing but praise.

Pros & Cons

After several years of Garmin, I switched to this Karoo (3). If you don't need extensive training options, this is a perfect device

Pros & Cons

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

Pros & Cons

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

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.

Best sat nav I've ever had! Simple route planning on the mobile phone, then sticks to the route. If you deviate from the route, you are guided very sensibly back in the direction of the route, which is world class. Switching on takes a little longer, but you can prepare for it.

After a 600km bike tour through Germany and Austria, I was pleasantly surprised at how well the route guidance and the connection with the SRAM gears worked.

After yet another disappointment from previous bike computer, went for the Karoo. Better than I expected. Easy setup, immediately made 2-day trip without a problem

Pros & Cons

New device and the battery lasted a full 8 hours with Allways on with Route.

I have been riding Hammerhead for years, it comes highly recommended. The controls are simple and clear which is a huge advantage. Very handy too is the website where you can very easily plot a route including preference for road or gravel/mountain bike. At the same time, you see the altimeters you can follow on the route.

Pros & Cons

Perfectly meets my expectations, quality product.

Quality GPS computer with all the features you'd expect from a top-of-the-range product

Upgrade to my old Roam V1. Screen much better to read for my aging eyes, displaying of route and rerouting very good. Battery life a bit below the roam, but can be tweaked by battery saver function. All in all a very good decision.

Pros & Cons

I've only had the Karoo for a short time and so far it hasn't let me down a single day. The visibility is very good, the screens once adapted are much more intuitive than those of garmin. The main drawback would be the battery, which in my case with automatic brightness I don't think it will last 15 hours.

My previous experience is a Garmin Etrex H so the leap has been abysmal. For me everything is positive except that I miss a silicone case, bought in a different shop (it would be nice if you offered it in Mantel) because I see the screen sensitive to breakage to blows in the frames. I hope it lasts like the EtreX and I took it off out of boredom rather than because it stops working ;) It's going to be used not only for cycling but also for Indoor with smartbike and trail running.

Great device with very good support on line. Good pairing with Strava and my Sram group.

Pros & Cons

Wow! Beautiful screen, looks like 4K resolution. If you are looking for a bike computer that connects easily with sensors from other brands and yet is just that little bit different from a Garmin or Wahoo, you have found it!

Pros & Cons

Before this, I had the Karoo 2 and used it very intensively for three and a half years. The only problem I ever had with it was the battery, which deteriorated badly over time. Since everyone swears by Garmin, I first ordered one of those as a replacement, but it went right back. Once you get used to Hammerhead's intuitive controls and especially its beautiful visuals, you can never go back to another brand. So for me, the Karoo is the only bike computer I want.

Pros & Cons

I bought this device ahead of a cycling holiday in Scotland. Meanwhile, I have been using it intensively for a few weeks. Some searching in the beginning (how to set everything to your liking, etc.) but after a while I was totally hooked with the controls. Everything speaks for itself / feels a bit like smartphone controls. With my previous device (a Garmin Edge Explore), the screen regularly crashed. Then you had to restart the device with the risk of the route you had planned disappearing. Moreover, it always took a while before the GPS signal came in and the route was recalculated. The Hammerhead works smoothly. The screen does not crash, even in battery-saving mode. If you turn the GPS off during your ride, you can easily pick it up again afterwards (the data from the ride remain saved). According to Hammerhead, the battery should last 15h. I haven't tested this yet. But on day rides of more than 7h, I still zltijd end up with more than 50% battery. Apart from that, I manage to charge the GPS while cycling with a Son hub dynamo (usb connection with Cycle2Charge). This way, even on a relatively flat ride, I manage to keep the battery at 100% when the device is on battery saver mode. The data screen is very handy. Especially the part around climbing provides very clear and predictable info. Other than that, few downsides. Too bad it doesn't manage to plan a route without Wifi connection. A silicone case to protect the GPS would be handy. Highly recommended. I am very satisfied with this purchase.

Pros & Cons

I already had the Karoo 1 and 2, now the Karoo 3 - simply the best in every respect
