I am currently working on a final year project in which ultrasonic ranging and
triangulation plays a large part.  I have a problem at the moment with
finding suitable transducers to provide the required accuracy.

I am looking for either:

(1)	standard frequency (40KHz) transducers with a very fast transient
	response - ie ideally I want an immediate response from them

(2)	compact, light, fairly high-powered high-frequency (100KHz+)
	transducers

Any ideas?

Thanks in advance, again
