GoPro hero 7 good for slowmo?

are you trying to use it for scope cam footage? if so you need a lease change

Yes trying to use gopro7 black ($350 verison) with side shot to record my video in 240fps to see my shots. You mean I need to buy extra lens? I can just use the GoPro with the side shot mount? I do not own a GoPro btw. I'm asking cause if it works then I'll go and buy it. I think the one called backbone or whatever comes with the lens but it's too pricey for me. Almost a thousand dollars. Then add the $270 side shot and it's gonna be $1000 and more.
