What is a chirp sub bottom profiler?

A Sub-bottom profiler is a type of sonar system that produces a 2-dimensional stratigraphic cross section by using acoustic energy to image sub-surface features in an aquatic environment.

How does a sub bottom profiler work?

Sub-bottom profilers work by transmitting sound energy in the form of a short pulse towards the seabed. This sound energy is reflected from the seabed and the sub-surface sediment layers.

What is a parametric sub bottom profiler?

The Tritech SeaKing Parametric Sub Bottom Profiler (SBP) allows you to obtain a clear picture of what lies below the seabed and this compact, low power unit, ideal for ROV and AUV use.

How does a CHIRP transducer work?

Instead of pinging a single frequency like traditional 2D sonar, CHIRPing devices transmit a sweeping range of frequencies. With each pulse, the transducer starts vibrating at a low frequency, which is then modulated upward to a high frequency over the duration of the pulse (130 to 210kHz, for example).

Is high CHIRP good for shallow water?

Medium CHIRP or 83kHz—Specifically designed to give the widest coverage area, 83 kHz is ideal for watching a bait under the transducer in shallow water. High CHIRP or 200kHz—Higher frequencies display a higher resolution image making it easy to discern fish from structure or structure from the bottom.

What is the advantage of CHIRP?

Pulse Compression and Pattern Correlation CHIRP improves bottom tracking at higher speeds and deeper depths. It helps resolve individual targets—no blobs, but instead crisp separation of adjacent objects. The result is a spectacular improvement in the image you see.

Does deeper chirp have GPS?

Inbuilt GPS (Deeper PRO+ and Deeper CHIRP+) The Deeper PRO+ and CHIRP+ has an inbuilt GPS receiver. This means that these models do not need to be in the same location as your smartphone in order to create maps, so you can map by casting it out.
