Garmin 77/200 Transom 8 Pin
This is Garmins 77/200kHz transducer which can be used with most Garmin 8 pin models, such as the echomap series and gpsmap 557xs and 751xs.
It has a wide beamwidths of 45 and 15 degrees - making it suitable for harbour and reasonably shallow use (up to about 60M.) We have had these transducers reading in 300M on an echo 500C sounder, but they're not really designed for it.
If you have any questions as to whether this transducer is suitable for you, please don't hesitate in calling us!
