I am assuming you are referring to the Polaroid "Ultra-Sonic Ranging System"
"hacker's kit".  I've tinkered with it before when I was playing with robotics.
I happen to have the old manual with specs in my library.
Here's what it says:

Ultra-Sonic Ranging System   (Polaroid)
Comes with:
	(1)  1 Polaroid Instrument Grade Electrostatic Transducer.
		Part # 604142
	(2)  1 Polaroid Ultra-Sonic Ranging Board (modified)
		either 4-freq Part # 606745 or
		       1-freq Part # 607089
	(3)  1 Experimental Demo Board
	(4)  1 Polaroid Circular Polarizer
	(5)  2 Polaroid Polapulse Batteries
		Part # 604152
	(6)  1 Polapulse Battery Holder
		Part # 604145
	(7)  1 Cable Assembly
		Part # 604789
	(8)  Assorted Connectors and Wires

If I remember correctly the whole kit fell within the $100-$150 range.
Keep in mind that the info I have is circa 1985.  It's a nice kit
though and gets you started pretty well.  The manual supplies full
schematics, data sheets, and theory.  All of the above parts are also
available separately.  Here's the info you asked for:

		Polaroid Corporation
		Commercial/Battery Division
		575 Technology Square - 3
		Cambridge, MA   02139

		Phone# (617) 577-4681

I have no affiliation with Polaroid other than being the standard,
satisfied customer.
