Jerry , i have priced a Vertex system . I gave them a drawing at the Pond Boss Convention showing the diff. depth's and the shape of my 1.6 acre pond , They took an aireal photo and figured what I needed . Todd Overton is there local distributer. I am going to do it but have not had the time to mess with it yet. they will install or I may do it . My wife want's me to let them ! she's afraid i'll screw it up . LOL
