SK Telecom mobile phone fish detector

South Korea's SK Telecom has come up with an unlikely addition for its mobile phones: an add-on device that promises to help anglers tackle their battle with the fishes. A waterproof transmitter is attached to the end of a fishing line and sends out ultrasonic pulses to gauge the density of fish in the surrounding water. This information is sent back to a receiver plugged into a mobile phone and software on the handset displays this information along with additional data, such as water temperature. The transmitter and receiver cost around $100 and the software can be downloaded to the phone for about $5. It won't be available in the UK.
