Did anyone else watch the Phelps video commercial? He talks about how great the system is and then he says it would be great for “triathletes.” I feel this was intentional, because as a pure swimmer he would be poorly portraying the sports image if he wholeheartedly endorsed the product. He alludes to training in the player holder system, but I get the impression that he thinks it’s a gimmick.
All that said, they must be great for triathletes who don’t get excited about staring at a black line
