Sonar comes from “sound navigation and ranging”. It is a system that uses sound transmission underwater and navigating or detecting objects on or under the surface of the water. There are two types of this technology: passive sonar and active sonar. Passive is essentially listening for the sound made by vessels. Active sonar is emitting pulses of sounds and listening for echoes.
A Sub Bottom Profilers is used to identify the thickness of different strata layers below the ocean floor. Most importantly, it will also show any density disturbance within a strata layer. It’s the density disturbance that indicates something foreign within the strata layer.
We offer three types of these devices. There are a direct scanner, several side scan tow-fish and a sub bottom profiler. For the side scan, we have the single-frequency SSS600kHz. Also, there is the dual-frequency SSS600kHz/1200kHz. The SSS450kHz/900kHz CHIRP side-scan sonar is also a dual-frequency device.
A sub bottom profiler is another device in this category. It identifies the thickness of different strata layers below the ocean floor. The sub bottom profiler called the SBP-1 shows any density disturbance within a strata layer. It’s the density disturbance that indicates that there is something foreign within the strata layer.
