This chrono is pretty nice. All you do is press the button, take a shot and it will say ex: 2-85, then you have to press the button again and take another shot. Its very durable and compact, easy to carry around unlike the big red chronys. I got mine for pretty cheap, 80$, and I dont regret buying it at all. Everyone uses it at my friends field and its a mandatory thing to have to make sure we play safe.
I recommend this to anyone who is making a field. Its a really nice chrony, and can be very useful.
