The SeaBat 7160 provides an unbeatable combination of range, resolution, portability and powerful features. The SeaBat 7160 transducer array is comprised of linear receive and transmit arrays mounted together on a support base. The T-shaped array geometry provides the basis for a compact, high-resolution sonar which is easily installed for portable or hull mounts – a first for a high-resolution system in this frequency range. The system features a pitch-stabilized transmitter and an active roll compensated receiver. Performance enhancements over the SeaBat 8160 include the addition of 512 high density equi-distant beams, variable swath coverage, beam uncertainty measurement, water column data and many other efficiency enhancing features.
