My thought, that's almost deceitful of digitec :-(

The camera is waterproof up to 18 metres without a housing. With a special housing, it can be submerged up to 60 metres.

The battery of the DJI Osmo Action 4 lasts up to 160 minutes, depending on the recording settings and environmental conditions. At temperatures as low as -20°C, the camera can also record for up to 150 minutes.

The camera can be mounted on a tripod with a standard screw thread system using appropriate accessories. For example, the Adventure combo includes an extension with a 1/4"-20 thread, allowing it to be attached to a standard tripod. Additional accessories such as cages or adapters can also be used to facilitate this attachment.

The battery holder and extension bar included in the action camera adventure combo are practical accessories for extending battery life and shooting flexibility. - Battery box: This is a multifunctional box that can store up to three batteries and two microSD cards. It can also be used as a power bank to charge other devices via USB-C, but must be connected to a power source to charge the batteries themselves. - Extension bar: The 1.5-metre extension bar allows you to take selfies from multiple angles, which is particularly useful for activities such as skiing or other sports.

You also need the rucksack holder. I bought the carrying straps straight away, so I can use it anywhere.

I think you'll find the answer to your question by searching for "DJI Osmo Action 3 vs DJI Osmo Action 4" on YouTube. I can tell you though that the price of the Action 4 should come down soon, as the 5 is about to be released 😉

Unfortunately no carrying case included. But it's pretty tough and I now know that I only need one battery for day trips. I just plug it in like that.

-No the cam does not have built-in GPS -Yes drag&drop -The videos are in MP4 (H.264/HEVC) -Photos in Jpeg/RAW -Sound is ok for a few words but not as good as an external microphone

Hello ! I'm not sure you'll be able to attach it to the inside of a motorbike helmet, but I'd recommend the DJI Mic 2 Bluetooth microphone (on sale at Digitec). That way you won't need a cable, and your camera will remain waterproof! Have a good trip!

Yes, depending on the video quality and battery life settings and the size of the memory card.

Hi, yes I do but later. Need to gain some more experience with it.
