In the process of identifying seafloor objects, the hydroacoustic method using 2 beams, namely ports and starboards in side scan sonar instruments is a very efficient and renewable method in its field, especially in the hydrographic field. This study was carried out at December 2016 on Punggur waters, Indonesia (104°05.6103 E, 1°04.3226 N until 1°03.3977 N 104°07.9100 E, 1°02.2866 N). The side scan sonar used when recording seabed images in this study uses one frequency, 325 325 kHz covering surface around 4.72 km in Punggur waters, Indonesia. The ship navigates using GPS Trimble 361, which is corrected using beacons, with data retrieval activities when the waves are calm. The gain produced by the side scan sonar instrument will have a relationship that will not be the same at every seabed data collection location. Side scan sonar uses a Baudrate value of 19200 and with a value of 8 bits with a maximum Gain value of 8 dB. Highest result of the time is 13568 cm/second and 104.325 cm in line trace object 4 of side scan sonar imagery. Highest result of line trace is target 1 with 191.88 cm on object 1, and highest of time result is 13568 cm/second on object 4.
