I think most take it off, That would drive me nuts to have that hanging at an angle not reading correctly.
Why do the Humminbird ICE Series flashers have two cables on their transducers? Humminbird's transducer assembly contains both a support cable and a signal cable. The support cable hangs the transducer at the proper position in the water, and the signal cable connects the transducer to the control head. Because Johnson Outdoors believes in respecting the intellectual property of others, we specifically designed our assembly such that it would not infringe a specific patent relating to suspending an ice fishing transducer by its signal cable. For that reason, the transducer should be utilized per the instructions in the owner's manual at all times.
I don't use the support cable here either, but now I'm curious. Where did you guys get that swing arm from??
