I was frequently having an issue where the transducer would raise up.
This happens when the wind is blowing from the side with the transducer arm mounted so the kayak is being pushed away from the arm.
Tried tightening the arm, but would still happen.
I always have a rope tied to my kayak for tying off to trees, in case I or someone needs towing or to help cart my kayak back.
The rope floats so i put some out on the downwind side of kayak and let kayak float over it.
Tie end to the transducer arm and tie a half hitch around handle for rod holder on downwind side of kayak.
Only issue is if line or bait bucket line gets hung on transducer arm need to undo half hitch so can lift the arm and free everything.
Decided having good readings from the finder outweigh this.
