How sensitive are the regular 40 KHz transducers that are available, are they any good outdoors in windy conditions and in our famous indian summers?

Also, do you guys know of resellers who stock transducers that go in the MHz range?

The regular 40Khz transducers are not good in summers.They are not good for anything beyond 25 degree Celsius.I have a ultrasonic distance dis-player circuit it never shows the correct reading i mean it has a zero error of 4cm & most of the time the distance fluctuates badly.
