With the general release of Google Glass still some months away, a Canadian rival has already started taking pre-orders for a wireless eyewear product, CNET reported yesterday.

Vancouver-based Recon Instruments debuted its Recon Jet - which incorporates elements of the Android OS - at Google I/O last month and is now taking advance orders for $500 that will ship in December. The full release price for the wearable heads-up display will be $600.

The Jet is aimed primarily at sports enthusiasts and its Bluetooth- and ANT+-based tech will allow athletes to collect a range of bioactivity data including heart rate, speed, distance traveled and power output, and show it on the display imbedded in the bottom of the right lens.

Recon has plans to launch a software development kit prior to December to foster app development for the device.

"To say the response exceeded our expectations would be a massive understatement," said Recon CEO Dan Eisenhardt.
