We started using it this year..and yes without question if helps. We started about two weeks before Seth S. came to the lake for a clinic. We videoed all of his coaching and ended up with 20 gig's. And just like Ed pointed out, don't focus only on the negitive, Identify what your trying to change, and because we catured everything Seth was seeing and what was said in between passes we look to see if were staying on top of what was taught. It's been two weeks since he's been here, buoy count is about the same as before he came but the video's look so much better. Couple more weeks and buoy count will be up and our plan is to keep recording.
