I know this question has been asked before (probably numerous times), but would like to get current opinions/preferences regarding Lakemaster/Lakemaster Plus versus Navionics mapping chip(s)/cards). I realize that not all lakes are on Lakemaster. I am specifically interested in opinions regarding mapping for High Rock Lake which is on both cards. I would love to know which mapping is preferred and why to help me with making an educated decision about which mapping card I will purchase. Thanks in advance.
