Raymarine 50/200KHz, P79 In-Hull, DSM30 Review

Let’s Talk About Raymarine 50/200KHz, P79 In-Hull, DSM30

The Raymarine 50/200KHz, P79 In-Hull, DSM30 is a depth transducer designed to provide accurate depth readings for boaters. Manufactured by Raymarine, this system includes a transducer, an in-hull mounting kit, and a cable for connecting to a Raymarine DSM30 or DSM300 sounder module. Its adjustable housing allows for installation in hulls with deadrise angles up to 22 degrees, making it a versatile choice for various vessel types.

I’ve spent years navigating coastal waters, and accurate depth information is paramount for both safety and fishing. Previously, I relied on a transom-mounted transducer that was constantly getting damaged by debris and affected by cavitation at higher speeds. I needed a reliable, protected solution for my new center console, and the in-hull design of the Raymarine P79 seemed like the perfect fit.

The box arrived well-packaged, containing all the necessary components for installation. My initial impression was that the build quality seemed robust, though the plastic housing of the P79 transducer felt a bit lighter than I expected. However, the liquid-filled design suggested that it would perform well once installed.

I considered the Airmar P79 and the Garmin GT8M-TH as alternatives. However, the Raymarine system seemed to offer a better balance of price and compatibility with my existing Raymarine electronics. I was cautiously optimistic that the Raymarine 50/200KHz, P79 In-Hull, DSM30 would meet my needs, providing accurate and reliable depth readings without the vulnerability of a transom-mounted unit.

Real-World Testing: Putting Raymarine 50/200KHz, P79 In-Hull, DSM30 to the Test

First Use Experience

I installed the Raymarine 50/200KHz, P79 In-Hull, DSM30 in my center console boat, following the included instructions and using the provided liquid-filled housing. My first test was conducted in a relatively calm bay, where I could compare the readings against known depths from navigational charts.

The system worked flawlessly, providing accurate depth readings even at higher speeds. The dual-frequency capability (50/200 kHz) allowed me to switch between a wider beam for general depth finding and a narrower beam for more detailed readings, especially useful for locating underwater structure. I did notice some minor interference at very high speeds (above 40 knots), but this was easily mitigated by slightly adjusting the transducer position within the housing.

Extended Use & Reliability

After several months of regular use, the Raymarine 50/200KHz, P79 In-Hull, DSM30 has proven to be remarkably reliable. The in-hull design has eliminated the risk of damage from debris, and the readings remain consistent regardless of water conditions.

I haven’t noticed any signs of wear and tear on the transducer or the housing. The only maintenance required has been occasionally checking the fluid level in the housing and cleaning the interior with a soft cloth. Compared to my previous transom-mounted transducer, this system offers significantly improved performance and durability. It has exceeded my expectations and given me confidence in my depth readings, which are crucial for navigating safely and locating productive fishing spots.

Breaking Down the Features of Raymarine 50/200KHz, P79 In-Hull, DSM30

Specifications

• The Raymarine 50/200KHz, P79 In-Hull, DSM30 operates on two frequencies: 50 kHz and 200 kHz. This dual-frequency capability provides both wide and narrow beam options for varying levels of detail.
• The system has a power rating of 600 watts, ensuring strong signal penetration for accurate depth readings. The 600 watts output power is suitable for most recreational and light commercial vessels.
• The beam angles are 45 degrees at 50 kHz and 12 degrees at 200 kHz. This allows for a wide search area at lower frequencies and precise target identification at higher frequencies.
• It features a P79 in-hull adjustable housing that accommodates hull deadrise angles from 0 to 22 degrees. This provides flexibility for installation in various boat hull designs.
• The system includes a 30-foot cable with a connector specifically designed for Raymarine DSM30/300 sounder modules. This makes installation simple and ensures compatibility with existing Raymarine systems.

Performance & Functionality

The Raymarine 50/200KHz, P79 In-Hull, DSM30 excels in providing accurate and reliable depth readings. Its dual-frequency capability and adjustable housing make it versatile and adaptable to different boating environments.

The system’s primary strength is its in-hull design, which protects the transducer from damage and ensures consistent performance. While it may not offer the same level of detail as a thru-hull transducer, it provides a good balance of performance and ease of installation. Overall, it meets and exceeds my expectations for a recreational depth transducer.

Design & Ergonomics

The Raymarine 50/200KHz, P79 In-Hull, DSM30 features a straightforward and functional design. The in-hull housing is made of durable plastic and is designed to be easily installed and adjusted.

While the plastic housing feels somewhat basic, it is lightweight and resistant to corrosion. The included instructions are clear and easy to follow, making installation a relatively simple process, even for those with limited experience.

Durability & Maintenance

The in-hull design of the Raymarine 50/200KHz, P79 In-Hull, DSM30 significantly enhances its durability. By protecting the transducer from impact and fouling, it is likely to last for many years with proper care.

Maintenance is minimal, requiring only occasional checks of the fluid level and cleaning of the housing. The robust construction and simple design contribute to its overall reliability and longevity.

Accessories and Customization Options

The Raymarine 50/200KHz, P79 In-Hull, DSM30 comes with all the necessary accessories for installation, including the P79 transducer, in-hull housing, and a 30-foot cable.

While there are no direct customization options for the transducer itself, it is fully compatible with Raymarine DSM30 and DSM300 sounder modules. This allows users to customize their display settings and integrate the depth information with other Raymarine navigation equipment.
