What customers say
Serious offshore anglers highly praise the Raymarine B265LM transducer for its exceptional deep water performance and clarity. The dual Low and Medium CHIRP frequencies deliver superior target separation, allowing users to clearly identify fish arches even below 1,000 feet. Reviewers find this improved resolution essential for deep dropping and wreck fishing, leading to more successful catches. The robust bronze thru-hull construction assures excellent durability and long term reliability in tough marine conditions. While the initial cost is high and installation requires professional expertise, users agree the unparalleled sonar data justifies the investment for dedicated deep water enthusiasts.
Know before you buy
This transducer is designed specifically for fiberglass or wood hulls with a deadrise between 0 and 20 degrees. It is not suitable for metal hulls due to the bronze construction and potential for galvanic corrosion.
The Low/Medium frequency range allows you to switch between deep-water searching and higher-resolution target separation. The Low band is ideal for deep-sea bottom tracking, while the Medium band provides clearer detail for identifying individual fish and structure in shallower coastal waters.
Yes, it includes a factory-installed CP450C connector, making it a direct plug-and-play solution for compatible Raymarine sonar modules. Always verify your specific display or module's port compatibility before installation.
Bronze is significantly more durable and resistant to the harsh marine environment, making it the standard choice for thru-hull installations on fiberglass and wood vessels. It provides a secure, long-lasting seal that stands up to constant exposure to saltwater.
Yes, the B265LM features an integrated temperature sensor that provides reliable data. Because it is a thru-hull mount, it remains submerged at all times, ensuring consistent readings even when the boat is moving at speed.
Because this unit requires drilling a hole through the hull and ensuring a watertight seal, professional installation is highly recommended. Proper alignment is also critical to ensure the beam is directed straight down for the most accurate sonar returns.
