It will come with the mount that lets you mount it on any flat surface. Several mounts out there that let you get it higher. Personally, I see no benefit to having a graph on the bow if you have to spend all your time staring at the deck.
For the TM mount, you can fasten it with bit hose clamps, but a mount from Transducer Shields & Savers will keep it from being broken off when you hit a stump. Not cheap, but saving one transducer pays for it.
