A Ram mount will hold up and they are good mounts. The preferred method would be to mount it in your console but that is not always possible. If you mount it close to the gunnel, make sure you are careful when docking or tying up to a dock. The Lowrance HDS10 is a large unit and it may stick out past the gunnel creating the potential for it to impact with the dock. Not always the case but just be aware it could happen and keep a close watch on the unit when docking. My unit is mounted on a Ram mount and next do my console in the area I would refer to as the top of the gunnel and I love it there because I can position it any way I need to. The Ram mount will allow you to remove the unit from your boat very easily when you are not using it. In my opinion, you will like the unit and the Ram mount.
