oh boy

what I like about mine

• waterproof
• seemingly indestructible
• replaceable lens covers
• creates .mov files (native for MACs)
• easy to start stop
• has burst or time lapse still modes
• has auto -rotate, so that when I use them upside down the video file is already inverted to be right side up
• small
• lightweight
• cylindrical plane fuselage shaped
• has quick release mounts so I can use the same camera in multiple places while I ride
• not expensive
• can find used units on the internet so I have backups

what I don't like about mine

• no image stabilization
• sometimes I want a flat square shape for diff. mounting options

other aspects to the camera

• takes a never ending video clip unless I stop it & restart it. which is easy to do. so as I ride I start it, then stop it, then start it & stop it. I make these choices depending on what is happening, or not happening. if I see a highlight coming up, I'll start it then stop it soon after passing the highlight

other considerations

• what are you going to do with the video?
• how will you be viewing it?
• how will you be editing it? (if at all)
• how long do you want it to run or stay alive at what temperature? on my last ride due to the cold I was on my 3rd camera before the end of the ride cuz the 1st 2 died from the cold. (big fan of redundancy for example 3 lites so if 1 dies I still have 2)

consider what you want to get out of the camera. what is important to you? what have you seen that you you like a lot & want to emulate?

I won't share what mine is cuz I want all the used ones to myself ;-) & they are old technology anyway. the new gopros have amazing image stabilization. good luck w/ your quest!
