The German society recently has developed two families of portable subbottom profiler that permit, through the use of parametric frequency, to approach to the functions of echosounder and subbottom together. The physique principle on which these products are based is the propagation not linear of the acoustic waves, with high pression's condition, in water.
-
SES 96 Light and SES96 Standard. Are more used in geological different condition with water depth range 1-400m.
-
SES 2000 Medium. Is a new variant offer for water depth up 1500 m and equipped of portable and big size transducer.
-
SES 2000 Compact. Is the smaller subbottom profiler system and of low cost. Can be used in small vessels, checked by notebook, and provides good performance.
The main frequency of SES systems is 100KHz and the secondary frequencies are between 4 and 12 KHz.
