I never use digital. I always use the smartfind screen because an injun has it's own unique way of hitting on the screen. Unless I'm bored and desparate...OR in the mood to dig any possibility...I can tell an injun from a deep screwcap 9 out of 10 times. Even though I rely on sound first and formost...the "injun dance" on the screen is the final decision maker whether or not I dig that type of hit. All other hits I rely on sound 100%...but on an injun hit...I use the screen too.
