Yep, got a leak somewhere. Did the timing thing with the water meter
and found the three largest zones use most of the water.

My Problem: water bill came to $400.00 one month and $500.00 the next
month. Stopped using the sprinklers and dropped to $50 - $60/Mo.
My Guess: underground sprinkler leak
My Question: What is the easiest way to check the lines for a leak?
My Answer (up for review): Take out the sprinkler heads in each zone
and cap off the line, run the sprinkler water and see if meter turns.

Need help to see if this is the best way to check the lines, or will a
divining rod be better?
Any comments would be greatly appreciated.
