Review on Universal Ball Mount Transducer Electronic Compatible by Yung Kitamura

Overall this is a good mount considering it's 100% plastic. However, it is 100% made of plastic. The part that holds your GPS/Sonar display is a RAM clone, but again made of plastic. It's also missing the spring bar used to hold one side of the mount on the ball when it's removed. never mind I know most people don't put big displays and big gauges on their kayaks, so I won't go into detail about some of these "easy things". It holds a 5-inch display well and maybe even a lightweight 7-inch display. Anything else would be a boost. I give it high marks for adjustability and ease of installation. I would question durability, but only if the thing rattles during transport/storage and/or you are asking too much with a large 9" or 12" display.
