Which go pro camera for under car ?

Lots of models to choose from. Which one do you use for chassis recording ?

I'm a dealer for them and would recommend the new sessions its smaller and can mount easier. You love the shots it can get. Just have to use your phone as a screen since it does not have its own it just Bluetooths to your phone.

I picked up a new HERO3 from a coworker a few months ago. Haven't used it yet, but look forward to see what people are using.

Just strap joe under the rear bumper .

He is too diesel now....lol
His arms won't fit.....lol

Have to say this
I got a Replay XD Mini approx $135 Crazy good for the $$
Low light not a strong point but for the $$ I am very happy and...the perspective is normal not that fisheye junk
You can go to Youtube and see a good day time and what it will do in poor light at a dark track-- search david kluttz dragster and watch the ony 2 videos I have shot and posted so far--zip tied it on--mashed the button and Violia--a video of my car--no special mounts or crazy assec's needed

My wife bought the top of the line one... with a
bunch of extra stuff... I told her I'd be using it
a few times on my car... I didnt tell her it would
be under the car.. LOL
EDIT
I'll use my camera to catch the 1/4ing rear angle

i bought a knock off from amazon for $70 came with a bunch of different mounts and has wifi load an app in your phone or tablet and go video quality is pretty good just depends what your after
