What customers say
Customers highly value the Garmin B117 for its exceptional build quality and reliable performance. The bronze housing is praised for superior durability and corrosion resistance, making it a sound long-term investment for harsh saltwater use. Users report excellent depth tracking and clear bottom definition, even at cruising speeds, which is crucial for serious navigation and fishing. While the premium price is noted, most agree the professional grade reliability justifies the cost, resulting in strong perceived value. The main consideration is the challenging thru-hull installation process inherent to this robust design. Overall, the B117 delivers superior data quality, making it a highly recommended upgrade for accuracy.
Know before you buy
The low-profile design eliminates the need for a fairing block, which reduces drag and makes trailering your boat much easier. It provides the same high-performance sonar results without the external hardware that can catch on debris or interfere with water flow.
This model is specifically engineered for boats with a deadrise between 16 and 24 degrees. The 20-degree tilted element compensates for the hull's angle, ensuring the sonar beam points straight down for the most accurate readings.
Yes, it features an integrated temperature sensor that provides real-time water temperature readings directly to your compatible Garmin display.
This transducer uses an 8-pin connector, which is compatible with many Garmin marine electronics. We recommend checking your specific device's manual or connector port to ensure it supports the 8-pin configuration.
The 50 kHz frequency provides a wider beam and deeper penetration for offshore fishing, while the 200 kHz frequency offers a narrower beam for higher-resolution imaging in shallower water. Having both allows you to switch between depth and detail depending on your current fishing environment.
