Pearstone ShutterBoss Wireless Timer Remote Shutter Release

Pearstone's Wireless ShutterBoss Timer Remote (Canon 3-Pin Connection) doesn't just trip your shutter wirelessly. It's also equipped to handle a long list of timer functions: self-timer, interval timer, long exposure timer, as well as controlling the number of continuous shutter releases. It works with a vast array of different cameras--just swap out the camera release cable for the correct camera. The transmitter works at distances up to 250' (80 m) on any one of 99 channels over a reliable 2.4GHz frequency.
Timer delays, exposure times, and intervals can be set for up to 99 hours, 59 minutes, 59 seconds, in one-second increments. You can also choose anywhere from 1 to 99 continuous shots or you can set the timer to take an unlimited number of photos. The receiver uses a CR2 lithium battery, and the transmitter uses 2x AAA batteries, which can last up to 4 years on standby.
