The SonarCE application is a real sonar for Pocket PC devices. It uses the internal Pocket PC sound system to detect echo from different obstructions. It is quite precise around 5-10 cm at distance of 10 m. The up distance is only limited by the output power of the device and the speaker. This program can be use in air or in water but in water you need external microphone and speaker closed in water proof case. http://nerdipedia.com/tiki-index.php?page=Sonar+CE |
