Humminbird 710273-1 XI 9 1521 Ice Transducer

used this transducer twice on the ice first time maybe 3hrs and second time quit working 1.5hrs in, will see what hummingbird does when I get a hold of them tomorrow. Quite disappointing considering the majority of there products are well built and last.

As described

Worked awesome and easily! Turned my Helix 7 into an Ice Helix with 1 plug and the push of 1 setting button. Highly recommend if youre hitting the hard water with a Helix.

Had to purchase a different gift

Works great on my Helix 7

Works good exactly what I wanted

My buddys Markum causes this to have significant interference.

Works perfect for converting helix 7 to ice!

Completely faulty ducer. Had to call humminbird and get a new one sent out. On back order wont get a working unit for 3 plus weeks.

I purchased this transducer to convert my boat use helix 7 to use on the ice , barely 2 months into the season and the transducer craps out on me , very disappointed in your product . Go back to the drawing board Hummingbird , this product is inferior and should have been perfected by r and d before ever being introduced to the market . Im going to dust off my 25 year old Vexilar f l 18 and forget about using my Helix on the ice . Get with the program Hummingbird , if Vexilar can build a transducer that last me 25 plus years then what seems to be your problem ? Extremely disappointed in Hummingbird .
