Leaking sprinkler head

I recently purchased this home in February 2015 and have been fighting some very soggy areas around several sprinkler heads. This is a low area where I believe the zone is draining. Attached is a picture of the head after turning off the system. Is the head bad or do I need another kind of head that won't drain after turning it off?

The valve which controls that area probably isn't shutting off all the way.
Repair or replace the valve.

This is the only head of 5; also, this head blows a lot of air when I start up the system. If the valve was bad, wouldn't i see this on all the heads?

All I know is you said you had a lot of soggy spots. Either you're over watering or there's a 24 hour a day leak. Are the soggy spots in the shade?
If it was just low head drainage then usually only one spot would be soggy.
You could install sprinklers with check valves in them to avoid drainage.

Yes the lowest head is draining all the water out of the line and you'll have a lot of air when the system first starts up.
It's hard to tell from here. You'll need to figure out if the valve isn't shutting off 100%.

Mr Fixit --
My apologies - you are right when i said several soggy spots. I failed to mention it was in different zones. I think you hit it - check valves in the sprinkler heads! That's what I recall... Thank you!

I have Rainbird rotors; what do you recommend for rotors with check valves?
Best, Jason

I like to match whatever is already installed.
I'd buy the same model sprinkler you have now but with a built in check valve.
Rainbird Rotors
Look for SAM's or Seal A Matic. = built in check valve.
