SECTION 4 OPERATION The SP-100D2 is designed to be portable and easy to operate. It is an ultrasonic, through-water communication system. It will enable you to talk to all other divers and/or surface stations on the same frequency and within range. When you speak using the SP-100D2, your voice is sent out in an omni-directional pattern via the transducer to all other transceivers. -
