Abstract: A portable depth-finder display support consisting of a cylindrical flexible bushing base, a tubular shaft and a mounting plate. The bushing base is sized to fit within the confines of a standard-sized cup holder such as those found molded into the deck structures of many recreational motor boats. One end of the tubular shaft is fitted into a substantially centered hole in the bushing base. The mounting plate is fixed atop the other end of the tubular shaft. The mounting plate has a plurality of circular openings specifically configured to accommodate the manufacturer supplied mounting brackets of many commercially available depth-finders.
