Odds and Ends 

PowerRay is an underwater drone for filmmakers or fishermen

The creator of the PowerEgg, an ovoid flying robot, has begun accepting orders for its newest creation, a submersible camera drone for home use. Dubbed the PowerRay, the waterproof device can find, attract and record fish. It operates at a depth of 30 meters, or about 98 feet, for up to four hours at a time. It issuitable for use in fresh-, salt-or chlorinated-water.

The PowerRay garnered buzz when PowerVision Technology Group first announced it at CES in January 2017. Of course it was a crowd pleaser among technophiles. But it remains to be seen how outdoor and marine biology enthusiasts may embrace or reject this technology.

The basic package, thePowerRay Explorer,has a 50 meter cable that tethers the device back to a base station above water. Besides keeping the drone from getting lost in a strong current, the cable transmits power to and video from the PowerRay back to the base station.All PowerRays have a 4K camera on board. ZEISS provides optical components to PowerVision.

The mid-level package, the PowerRay Angler, gives fishermen a way to cheat, homing in on prey underwater with the companys Powerseeker Fishfinder, shining lights and dropping bait to attract them using a remotely operated Bait Drop Line.

The PowerRay Wizard edition includes a VR headset that lets users watch what theyre recording in a kind of immersive open water exploration that doesnt require a wetsuit.The PowerRays cost from $1,715 to $2,250 (or 1,599 to 2,099) and are being sold first in European markets.

PowerRay faces competition in the US market from makers of other underwater drones and waterproof cameras, most notably the deeper-diving Trident made by startupOpenROV.

PowerRay footage captured underwater at the Aquarium of the Bay in San Francisco.

PowerVisions US CEO, Chih-Che Tsai, told TechCrunch, hedoes not view PowerRays features ascheats for fishermen. He said, Fish finders are nothing new. You have sonar systems that help you identify the landscape and where the fish are, already. Instead of putting it on theboat, we are just letting you move it around to go out and find the fish.

We met up with the CEO for aPowerRay launch party at the San Francisco Aquarium of the Baythis week. The aquarium barred PowerRay pilots from swimmingin tanks with sharks, because they would be likely to try to eat the submersible drones.

However, we were able to see the PowerRay approaching perch and sea bass and a range of other marine wildlife, as well asnavigating through the currents and kelp in the aquarium tanks.Surprisingly, the fish didnt flee. Then again, as fish go, these were already fairly accustomed to electronics.
