newby here....i am involved with a project that requires me to design/construct a rangefinder that needs to be rather compact, quiet and accurate from 30-180 ft. my biggest problem is, i know nothing about electronics or how/where to even begin looking for parts or schematics to start putting one together. this is all greek to me. the preference is a digital rf, though i imagine a laser may work. any help and guidance would be greatly appreciated. thanks.

Do you realise how difficult it is to get a sonic range-finder to detect 180 feet?
Go to the hardware store, buy a sonic range-finder, pull it apart, and use the components.
