The Aobelieve Sunshade Screen Cover is made for Garmin ECHOMAP UHD2 92sv, 93sv, 94sv and 95sv fish finders only. It is not a universal cover, so please check your fish finder model before ordering. This cover works in two ways. Open it during bright outdoor fishing to create a top and side shade around the display, helping reduce glare when checking sonar, maps or navigation information. Close it when the unit is not in use to help cover the screen from scratches, dust, outdoor debris, splashes and light rain during storage, carrying or short outdoor stops. The hard ABS plastic construction gives the cover a rigid shape, while the foldable side panels snap into the lower slots for stable normal use. Installation requires no drilling, screws or removal of the original bracket on compatible flush and gimbal mount setups. When open, the screen, side buttons, ports and bracket knob remain accessible.
