Powervision appear to be releasing an 8K version of the PowerEgg X drone.
I have the original PoweEgg X (4K), and while it is one of my most favourite drones, and my experience with customer service was exemplary, I can’t help but feel that this drone, like the original, will not make it above periscope depth as far as popularity is concerned. The original was only released in Feb2020 but those all important replacement batteries have not been readily available for the best part of a year. Batteries determine the usable lifespan of a drone.
