Lake Master chip

I bought the Lake Master chip so my Minkota could follow the contours. I got the chip at Bass Pro in Concord . I asked the sales guy which chip I needed because I fish Wylie, Wateree, Badin, Norman.
Last weekend I was on Wateree and had no contour lines, I'm thinking dummy I've got the setting wrong. So I look at the lake list and Wateree isn't on the chip, Wylie is listed on the North Carolina list and it has contours in the SC side.
The I emailed HB about it asking if Wateree was on the chip ( giving them my chip #) they said no it isn't. So I ask which chip I needed, their response was the same chip I have.
Not a happy camper

Guess that means they haven't done a contour survey on that lake yet. Could be the case.

navionics has a decent map for wateree. I use their free web app a ton too. Navionics Webapp

I second the free web app comment. Seems like they recently made a change where you can share links and it will keep the same position/zoom settings, so it's pretty useful for saving bookmarks or sharing with friends. For $10 or so you can get the web app on iPhone (not sure about Android). Comes in pretty handy as a supplement to a map card.

I'm not sure what the problem is my Navonic chip has the contours and it's old. Unfortunately the MK won't work with the Lowrance
