FM - It works great, I didn't really think of it myself, a lot of guys up at KY lake have something similar. The big thing up there is fishing stakebeds but if you have the ducer on your TM, you are on top of the stakebed before you know it. That isn't a big deal in deeper water but right now, the best stakebeds are in shallow water but still deep enough that you can't see them, so it helps a lot. With the ram mount you can aim it ahead of the boat at an angle or straight down, whatever you need. The downside is that your GPS puck isn't very close to the ducer so if you find a good mat you still need to get the GPS puck over it to get an accurate mark.
