Sonda wewnętrzna DSMxx/DSM300/CP370 (P79)

The Raymarine P79 internal transducer is designed for installation without hull penetration. Unlike through-hull or transom-mount transducers, it is mounted inside the boat, eliminating the need to modify the hull structure and reducing hydrodynamic drag. It provides a discreet solution for fish detection.

The Raymarine P79 transducer operates on a dual frequency of 50/200 kHz. Here are their main applications:

50 kHz: This frequency is typically used for deep-water detection or to obtain a wider beam, allowing coverage of a larger area beneath the boat. 200 kHz: This frequency provides better resolution and accuracy for fish and bottom detection in shallower waters, making it easier to clearly identify targets.

The Raymarine P79 (E66008) transducer is specifically compatible with the following Raymarine sounder modules:

It is designed to integrate seamlessly with these Raymarine equipment generations.

No, one of the main advantages of the Raymarine P79 internal transducer is that it requires no hull drilling. It is installed inside the boat, providing a discreet and simple mounting solution.

Several factors can affect the performance of an in-hull transducer such as the P79:

Hull material: Performance can vary depending on the hull material. Solid fiberglass hulls are generally ideal.Correct installation: Proper installation, free of air bubbles and with optimal acoustic coupling between the transducer and the hull, is crucial to maximize efficiency.Hull thickness: A hull that is too thick can attenuate the depth sounder signal.Presence of air or foam: Any inclusion of air in the hull or between the transducer and the hull can significantly reduce efficiency.

Yes, thanks to its dual-frequency capability (50/200 kHz), the P79 sounder is versatile for various fishing conditions. The 50 kHz frequency is useful for deep-water detection with a wide beam, while the 200 kHz frequency provides better resolution and accuracy for shallower water detection. This makes it suitable for both coastal fishing and certain offshore applications.

As an in-hull transducer, the P79 is installed inside the boat's hull. This means no part of the transducer extends below the hull into the water. Therefore, it adds no additional hydrodynamic drag, which can potentially contribute to better hull efficiency and optimized fuel consumption compared to through-hull or transom-mount transducers.
