Overview
Designed for anglers who want sonar performance mounted directly to the trolling motor, this transducer supports MEGA SI, MEGA DI, and DualBeam PLUS operation for a versatile view of what’s below and to the sides. Its listed beam angles and frequencies provide multiple scanning options, making it suited to boat control situations where precise, real-time feedback matters. Built-in temperature adds another useful data point while you’re working structure or adjusting your approach. It is a purpose-built accessory for compatible Humminbird setups rather than a general-purpose transducer.

Considerations & Trade-offs
- Designed for trolling-motor mounting, so it is not a universal transducer solution for every boat setup.
- The feature set is specialized for MEGA SI/MEGA DI and DualBeam PLUS use, which may be more capability than needed for simpler sonar needs.
- Installation and compatibility should be checked against your existing Humminbird system and trolling motor configuration before purchase.
- The built-in temperature function is included, but the listing does not provide additional sensor or display details beyond that feature.
