Seen the advertisement for the Tachyon and it was pocketbook friendly.....
Camera operation is pretty straight foreword. You do have to purchase a mini memory card. The size you require is determined on how long your going to run the camera. I picked up a 16GB card.
In theory, the battery will last non-stop for 2.5 hours. We turned on and off the camera at each station, conserving the battery. Recharge (USB or plug) upon return home has been quick.
Also, by turning on and off the camera at each station it made viewing individual station videos manageable.
We took the camera to three clubs.
Dark areas (flying in front of trees/brush in the shade) can be an issue.
