Stop watches are also needed for between inning timing. Some of the larger Div-1 schools are installing pitch clocks but all do not have them so a stop watch is needed. I also use them in games when there is no between inning or pitch clock rule being enforced. This helps me determine if the crew is allowing two much time between innings. Anything around 90 sec. is good. Anything above we need to pick up the pace between innings.
The frames on Oakley's are what's important. There are tons of aftermarket lenses that fit Oakley frames that can be had for under $40. Here are a few.
