If I were to install a larger graph in my Sabre Id use the Sherms mount myself. I like the in-dash “factory” look vs. the off to the side look personally. I wouldnt mind it if i were mounting 2 graphs at the helm but for one Id go Sherms.Im opposite on the bow though, Id prefer a ballzout or RAM mount on the bow vs. a factory look close to the floor on the bow. Its easier to see and use in my opinion but I cant see the hood ornament on a Cadillac Im driving if I dont have my glasses on or contacts in. For the record, I dont drive a caddy…haPurchased new 5/4/15Bass Cat Sabre Vision EliteMercury Pro XS 150MotorGuide 75lb Tour EditionHumminbird – Stock (will be changing soon I hope)
