Just bought a GoPro Hero 2 - this weekend's nacho run should have been it's test run - but 2 important lessons have been learnt....
1. - after you've charged it for the 1st time and fiddled about with the settings - don't forget to turn it off again. Otherwise you fit it to the A-frame , turn it on... and get 3 second's filming before it goes flat! Alternatively change it's default power mode to power down after x minutes!
2. Take a 12V to USB charging lead with you so when you've been stumped by (1) above, you can at least charge it up and have another go!
Next time......
