Ultrasonic Radar

Using Ultrasonic Radar with HBridgePWM it seems that unless you have a 1-180 degree sweep of the HC-SR04 it only asks the bridge to turn one way.
I have tried different sweep angles with no success.
I would like a sweep of 45-135 degree.
Anybody know the answer to my problem?

Hey westies,would having the sensor moving left to right on a servo help?

Or maybe just en extra set of sensors to cover a wider angle, etc?
I don't know the answer but someone here will. : )
Thanks for your input,it appears that these sensors can be a little un reliable so trying different ones gave me better results
They are cheap on EBay.
