does anyone have a suggestion for a reliable sonar transducer that is functional in the 0 - 4 m range?
The only ones i know are from SonaSwitch(EDP company) and can measure from 6 inches to 10 feet
MINI-S & MINI-A
here:http://209.114.244.106/sonaindex.html
available from digikey website
or have a look at omron website http://oeiweb.omron.com/Products-Proximity1.shtm
Bruce have one model on his site SRF04
http://www.rentron.com/remote_control/SRF04.htm
this model is suppose to be able to measure 3cm to 3m range. Cheaper than MINI-S and MINI-A.
hope this will help you

Some years ago Electronics today international
published a sonar/radar which used 2 40khz transducers like
the one used in very old television remotes
