Installed the transducer on my boat and it immediately improved my ability to see fish and underwater structure. The color clarity is excellent, especially when fishing in deeper waters. Works well with both transom and trolling motor setups.
Stephen Randall –
Great value for the features. The CHIRP sonar helps separate fish from structure, which is a big improvement over older models. Easy to install and functions reliably in different conditions.
Phil Johnston –
The side scan feature is very useful for spotting structure and schools of fish. I’ve used it in both shallow and deep waters and it performs consistently. No issues with signal or clarity so far.
