1. HUGYFOT WATERPROOF CAMERA CASE

Canon x Hugyfot 5D Mk IV DSLR Camera

The Canon 5D Mk IV DSLR camera is excellent but not waterproof, let alone dive proof; and that’s precisely where the Hugyfot housing comes in. Built from a solid block of AlMgSi1 high strength aluminium that’s then sanded by hand, sandblasted and finished with a hard anodized and Teflon coating, it certainly looks the business. It also happens to be pressure rated to 100m. Naturally, the underwater housing still enables you to use all the standard controls on your camera. There’s a pair of handles for steady video capture, as well as a soft neoprene handle for one-hand photography.

Perfectly suited to shore dives and snorkelling – as well as general fun on and under the water – this compact personal propulsion device will speed you along at up to 3.78 NM (7km/h) for up to 90 mins, thanks to its three-geared, 500W motor. Additionally, it will take you down to an impressive 40m. Also, with the included GoPro mount, you can capture everything as you go.

4. POWERVISION POWERRAY WIZARD

PowerVision’s PowerRay Wizard

PowerVision’s PowerRay Wizard drone not only enables you to explore the deep from your boat or the shore, but it can also help you to fish. The drone is tethered to a base unit by a 230ft cable. You can watch the aquatic happenings on your smartphone or via VR googles in full HD, or even record in 4K. Two 450-lumen lights help navigate the murky depths whilst motoring along at 2m per second. Other notables include a sonar FishFinder attachment that scans for fish for you, and a bait dropper to then attract them to your drone.

5. U-BOAT WORX C-RESEARCHER 3 – 1100

U-Boat Worx C Researcher 3 1100

Diving can be exhausting for some. However, the U-Boat Worx C-Researcher 3-1100 enables anyone to get down to 3,600 feet below the waves. The sub boasts a wide field-of-vision, thanks to shoving all the mechanics behind the enormous domed cockpit. The precision controls are mated with auto-depth and auto-heading functions, which are all linked to six powerful thrusters. The interior has been designed for the utmost comfort, including ample head and leg room with luxurious leather seating. It can also be customised to match your yacht’s design themes, of course, while the same goes for the exterior finish.
