Thank you and we look forward to hearing from you!
The Olex system can be connected to the Simrad EQ60, ES60 and ES70 and Hondex HE-7300 Di and HE-1500 Di Echosounders. This makes it is possible to map the hardness of the seabed.
The system analyses the bottom echo; taking into account pulse length, beam width and transducer type. A bottom backscatter is calculated and added to the internal chart. The hardness is then shown in an easily read adjustable coloured format, ranging from deep pink for soft bottom to bright yellow for hard.
The actual echosounder data can also be shown with present and historic data.
