Recently, Japanese TV station FNN reported on an experiment in Okinawa prefecture using an ELTRES transmitter built for divers. A translation of the article appears below, and you can also watch the YouTube video (in Japanese) as well. Title: Device to prevent water accidents: Can transmit position 100km from land floating in the sea. Article: Amid a series of water accidents this month, including the death of one person diving off Iriomote Island and the disappearance of another, a demonstration test of a device developed to reduce the number of marine leisure accidents was conducted in Ishigaki City. A company in Naha City has developed a human-wearable GPS transmitter device. Even when the transmitter and the receiver are located more than 100 kilometers away, the location information can be shown on a smartphone or tablet. The device is waterproof, and the battery lasts a long time, so it is expected to prevent accidents if used for diving and other marine uses. Mr Iino, President, Quadra Planning Co., Ltd. said "People watching over the divers can realize that it is dangerous to go any further. Not saving people after they get into danger but preventing marine accidents from occurring in the first place." In a demonstration test, the company succeeded in tracking down equipment that had been previously drifted from Ishigaki Port and recovered it off Taketomi Island, and officials said they hoped to reduce the number of accidents by increasing its use.
