It provides standard depth string streams in $SDDPT, $SDDBT and $YXMTW at 1Hz, 4800 bps which makes the SLD-100 compatible with any Hydrographic Surveying Software package. SLD-100 is independently powered by an internal lithium battery which provides more than 10 hours of continuous operation. SLD-100 is extremely easy to use simply requiring the unit to be powered on to commence operation. Position and depth data is logged to any external logging device running compatible software. Mounting accessories for the SLD-100 and transducer are included in the package making it simple to mount the sounder and to attach a RTK GNSS receiver.
