Was fortunate to acquire a new to me Lowrance Elite 7 HDI. Its been a very long time since I bought a lake contour card. This unit takes the micro SD. My question...which card to get. I fish pretty much exclusively in the east Texas area. Fork, Pines, Rayburn, Sandlin, Martin Creek etc. (Live in Longview). I have no idea what card is "the better" one these days. Any advice??
