Just a quick google search of a price of a hummingbird will tell you not to buy 10 year old tech of an ice series.
Vex 18 helix 5-7 garmin uhd 5-7.
Vex fl8 if you are on budget and don’t go out much or want to learn the tech.
so don’t buy 10 year old tech with the bird, go with the 20 year old tech with the fl8 to save $50? comarping a ice35 to a fl8, for $50 more you get dual beam and adjustable depth to anywhere in the water column. Those two features alone are worth all of $50 to me
