Looking for an aerial drone is quite easy. There are a lot of great aerial drones out there, and some aquatic drones, too, but what seems to be missing are drones which can dive to 100 meters and still shoot 4K. This can be offered by the "Gladius Ultra HD 4K."

If you are a fan of the amazing view that the deep see offers, the "Gladius Ultra HD 4K" is for you. According to Techcrunch, this drone is a real beauty. It is controlled via a phone-connected remote and it is semi-tethered - meaning, it can out to approximately 500 meters with the right gear.

This underwater drone is able to record a maximum resolution of 1080p/60fps on the Standard, or 4K/30fps on the Advanced. An SD card is available where you can store your footage and 16MP stills. The Standard version offers a 30-meter (98 ft) Wi-Fi range, while the Advanced version offers 00 m (1,640 ft).

Both of these versions have a neutrally-buoyant aluminum alloy body. The control unit features video game-like controls, and a 720p video feed lets you see what the camera is seeing. Production funds for the "Gladius" are now being raised. The Standard version is priced at about $1,399, while the Advanced is at $1,699.

The drone weighs 3-kg (6.6-lb) and is being made in Standard and Advanced models, which come with a 30-m (98-ft) tether, and runs up to a Wi-Fi-equipped buoy that is towed along at the surface. Technode said that "Gladius" comes with two built-in lithium batteries, which can last up to about 4 hours on one charge.

This underwater drone comes with its one smartphone application which is supported by both Android and iOS platforms. The quad thrusters of the "Gladius Ultra HD 4K" is highly maneuverable. The piloting controls are easy to operate, and with its low-light sensors and image quality algorithms is a steal.
