Other than GoPro?

Im thinking of picking up a action cam for the water, looking at the Garmin Virb... looks great but I want to see what everyone else is using.
Pros and cons of each.
Like the battery life of the garmin is almost 3 hours of continuous shooting as per a youtube vid I was watching.

I want the latest gen sony..it has the wrist watch and a simple tap goes back and saves stuff to a previous time...i think ten minutes or 5.....then records everything till you tap again.....so lets say you hook a fish...and land it...tap the watch and 10 minutes back is saved...no turning on or off or missed stuff...it tapes non stop....see a shark all of a sudden or splashing fish/bird...it can be  saved...cause it is watching and not saving till you tell it...

That's gotta kill the battery, but sounds badass!

Hi Craig,
     I don't see any specs on the loop recording function.  My Drift Ghost HD does this and It's the way to go.  That Sony remote looks awesome.

yeah ---- I am out the door and was hoping that "loop record" function was talked about in that c-net review..I trust their reviews kind of...I'll check your ghost drift out too...I would think "loop record" or save back  etc...would be the way to go on a kayak...I broke every watch I've ever had period ,so that scares me....with the sony that is....

need to design a ball cap camera that you just tap the top of the cap and it saves the last 4 minutes and then go back to passive when you tap again...be a millionaire

I am out the door with fresh tied perch grub on a light action lamiglas...rained hard as heck all night here in Carmel valley and the bright sun if playing with a king kong island fog over on carmel beach..incoming tide till 10 a.m...gotta run boys

I want a better action cam and a better way to wear it than some cyborg head band...good thread here...even if it has been threaded a bunch already...new stuff and more reviews to the talk
