I bought a high fps camera years ago but didn't use it as often as I should have and now I realized what an idiot I was. Part of it stems from I hate looking at my swing, it's ugly, no it's fugly. My opinion now? Get over it. The camera is such a useful tool.
In the range near my parents' place, no one... no one, uses a camera, or least I've never seen anyone use one. Forget the tripod, no one even uses their camera phone. Even the pro. I was kind of hoping seeing other people using cameras would guilt me into using my own. And I get lots of stares, especially from older folks, some who walk right up to the camera to see what a curiosity it is. I cannot believe in this day and age, people don't utilize the technology that is available and it's not expensive. Forget Swingbyte or GolfMetrix.
Anyways, had to vent. TL;DR - use your camera. Get one and use it if you don't have one.
