It is suppose to float in the water and hold your transducer straight up and down. Some locators have an arm on them to hold the transducer vertically.
I never use the foam that comes with any of my fish finders... it’s just another thing that gets in the way.
On the vexilars...there is a rubber "knob" that slides up and down depending on ice depth that works as a "stop" for the float...if yours is missing contact vexilars I'm sure they can send you one.
I usually cut a hole right next to the hole I'm fishing for my vex.....I use the foam to keep the transducer from going to deer and tangling with a fish
I just have a cheap hummingbird ice 35 so mine has a float that I hate. I went the cheap ghetto route and use a wire coat hanger. I just wrapped one end to the unit and the other end I bent into a circle around the cord. This way I can bend the wire wherever I want it and it's super quick and easy to adjust. Just don't let your buddies see it or they will laugh at you.
I'm new to the electronics game. I just got an iceducer for my helix 5 chirp unit (open water not the ice unit). How far down the hole are you supposed to have the ducer? Just below the ice I'd imagine? Any other suggestions for a newbie?
