Have seen the mag shield but have never seen it in use. Does anyone on here use one?? Can they recommend it or not. I have no issue viewing the screen and can see it fine. However, was thinking that if it changed the viewable angle, meaning I could place the vex in the center of two fishermen in the shanty and it is easlier to view by both by each angler, than I may consider one. Other than that I really would not need one. Any input would be appreciated. ER
