"The Crocodile"

The Deluxe version of the "Crocodile" The viewing angle of 180° is divided into 10° units with complete vertical divisions every 30°. Viewing through the optical door viewer, will allow you to measure the angular size of the sound source.

The DIY version of the "Crocodile" The only materials that you need are a few long and short nails, and some offcuts of plywood. The nails are placed every 10° - the long nails being placed in the center, at +/-30° and +/-60°. A few more details are given in my book. [Return to Home Page]
