Garmin Transom Trolling Transducer f/echo™ Series Fishfinders - 4 Pin

The Garmin Transom Trolling Transducer for echo™ Series Fishfinders with 4-pin connector is a dual-beam transducer designed to expand the versatility of your existing Garmin echo fishfinder system. This transducer enables anglers to outfit multiple vessels with the same sonar technology or to switch between transom-mounted and trolling motor installations without purchasing an entirely new fishfinder unit, making it an economical solution for multi-vessel operations or seasonal gear rotation.

Built with dual-beam sonar architecture, this transducer delivers the same proven echo series performance in a compact form factor weighing just 1.05 lbs. The included mounting hardware accommodates both transom installation on boat hulls and direct attachment to trolling motor shafts, giving you flexibility in deployment without requiring additional brackets or adapters. The 4-pin connector ensures seamless integration with compatible echo series fishfinders, maintaining full signal integrity and feature access across your sonar display.

This transducer suits weekend anglers managing multiple boats, guides rotating equipment between day trips, or serious freshwater and saltwater fishermen who want redundancy without the cost of duplicate electronics. It's particularly valuable for bass fishermen transitioning between shallow-water trolling motor work and deeper structure fishing from the transom, where mounting location directly affects sonar cone angle and target detection. The weatherproof construction handles extended freshwater and saltwater exposure typical of active fishing environments.

Garmin's echo series represents a proven mid-range sonar platform trusted across the recreational fishing market. Adding a second transducer streamlines equipment logistics and maximizes the value of your existing display unit, eliminating the need to uninstall and reinstall a single transducer between vessels or fishing modes.
