TELEDYNE SEABAT T50R
The SeaBat T50-R is the latest addition to the SeaBat T-series product range. It features particularly clean data to provide faster operational surveys and reduced processing time. "The SeaBat T50-R is fully frequency agile from 190 to 420 kHz, allowing for improved swath performance and reduced survey time under challenging acoustic conditions," said Uni Bull, Product Manager. "It is designed for very fast mobilisation on any type of survey vessels, securing minimal interfacing and low space requirements.

"The SeaBat T50-R standard configuration consists of two parts – the very compact Rack-mounted Sonar Processor (RSP), and the sonar head assembly. "The standard 19in RSP is a single point for all cable connections and this enables fast mobilisation. For accurate sensor time tagging and motion stabilisation, it comes with an optional industry-leading fully integrated inertial navigation system." Meanwhile, the SeaBat T50 sonar head assembly boasts 190 – 420kHz wideband sonar arrays in a robust titanium housing. It weighs less than 8kg in water. "The system has a number of benefits," continued Uni Bull. "The all-in-one, fully flexible and fully integrated survey system is compact and allows for minimal interfacing and extremely low space requirements. "Because the sonar is fully frequency agile, it gives an improved swath performance and reduced survey time under challenging conditions. The new compressed water column data significantly reduces data volume while maintaining the required information. Normalised backscatter designed for accurate, reliable and repeatable sea bed classification. There are a number of optional extra features including an Integrated INS Type 20 or Type 30, an additional 10m, 50m or 100m of cable, a hydro dynamic fairing, dual head bracket, RESON sound velocity probes, Teledyne PDS survey package and motion and positioning sensors An X-Range can improve range and reduce external noise while MultiDetect can be used for enhanced detail over complex features and water column targets. Pipe detection and tracking can be used to optimise detection of pipes while FlexMode increases data density. The SeaBat T50-R output
