Need recommendations on a system to view behind the boat . Want a 15-17" LCD on the dash, what is everyone using

Why bother ???unless a canopy boat? Or big azz cruiser?
Turn your head around ... Seems cheaper to me

Maybe should have asked.
What style , kind of boat do u intend to use on???

Don't like turning my head when I'm running 130mph with boats around me. Also want to be able to video as well

All the Garmin 4200 series and up have video inputs for cameras so you could use that for the video screen. I don't know if you can tie in a recorder as well.

Can I just buy a go pro recorder and hook it up to LCD screen?

That is a good question. I have a gopro and am getting a Garmin 4208 for Christmas. (I was a very good boy this year! )

I will look through the instructions after I get it and see if that would work.

GoPro has a video out put so I don`t see why not.

At 130mph you wanna make sure nobody is passing in your blind spot makes sense

One thing to keep in mind using a go pro is that the video will be reversed. Garmin and other manufactures actually make reverse image cameras that you can install. I installed one on my 28 Skater in the middle of the motors. I suggest hooking it up and playing with the position so that you can see if there is any blockage. Mine works great and I like the fact I do not have to worry about the battery going dead, camera getting knocked off etc. Camera is mounted about grab rail. Made a custom wedge to set the angle.
I have mine hooked to my 5208 as an input along with a Nightvision camera in the bow.
