Welcome, I too, want to be more educated about umpiring and this board is really helping.
With gear and such, there are many choices to be had. Do not skimp on safety gear (mask, CP, plate shoes). If you have confidence in your gear, you'll be more confident behind the plate. Looking the part is a huge deal to the teams and to ourselves. Yesterday, the umps that did our game looked poorly (track pants, un-tucked shirts, shinguards on the outside etc...). The other coach asked us if we had ever seen these guys before-noone had. I said maybe they'll be the best we've ever had-always trying to be the optimist. I was wrong. They weren't all bad, but, they didn't look like they took it seriously.
Once again, welcome and I hope you enjoy it!
Dave.
