I am interested in buying a Matrix 47 3D because of its 3D capability.<br /><br />I am wondering if anyone has any thoughts/experience with it.<br /><br />I notice none of the other main manufacturers of depth finders offer a 3D version. Is that because it is patented by Hummingbird or it is just not worth a darn.<br /><br />I would love to see a review on depth finders but I can not find anyplace to see it.
