Graphical echo sounders make it easy and accurate to identify what is happening below your boat. A probe can give you information about the nature of the seabed (rocky, sandy, algae, etc.) or very precise information about the nature of the obstacles (fish, rocks, shipwreck, etc.).

Among our references of used graphic sirens, you will find various technologies according to your needs and your budget: inaccurate entry-level models, mainly black and white and non-tactile that will allow you to reliably identify obstacles with relative precision, often enough. to keep your boat safe when launching. Chirp models allow modulating the frequency of the acoustic waves and thus have a better return signal and therefore a much higher and clearer precision. However, be careful to check the compatibility of your probe with this technology. Finally the so-called "multibeam" devices. These are high-end mermaids used by professionals and researchers in oceanography. Capable of emitting several narrow beams, these sirens will allow you to obtain images of a complete area and, depending on their computing power, analyze the echoes received by each beam.
