Humminbird 710273-1 XI 9 1521 Ice Transducer

My buddys Markum causes this to have significant interference.

Great transducer, sharp accurate CHIRP imaging for CHIRP enabled helix 5 and 7 sonars.

Worked great with our helix 7

Buyers beware!

Works great with my Helix 7g2 di gps

Worked great just make sure to order the right one for your unit. If unsure call hummingbird

Works perfect with helix 7 g2. Best ice setup ice used yet.

I put this on a helix 7 for ice fishing works fine but I think vexilar has there transducer down. This hummingbird needs to be weighed down wanders around the hole. Other than that seams fine.

This product works just as advertised, and does a great job marking fish, 10x better than the transducer that comes with the fish finder.

Works great on my Helix 7
