I gooped my transducer in the hull only to find out it didnt work when i got out on the water do to air bubbles i assume. i asked another yaker on the water how he rigged his. He just had his transducer in a bag of water in the hull. He gave me a extra bag and so i pulled mine out of the goop and put it in the bag with some water and it worked perfect. its a quick and easy way to do it. your setup looks pretty legit tho. thanks for showing it. its awsome the way this sport keeps advancing.
