[QUOTE="Browneye, post: 482890, member: 1051"] So now I'm using a 25 year old terrova thats been rebuilt once but still works. I have always wanted to be able to do the follow the contour feature. Contemplating getting a new terrova with the link and hopefully improved spot lock. I'm running an 859 with a lakemaster chip that is probably 10 to 12 years old and 7" with sidescan that I have a zero lines card in and have done some mapping. For those that have the follow contour feature how well does it work for you? I know on some lakes my lakemaster chip only has contours marked maybe every 3 to 5'. Does that mean it will only follow a line that is on the chip or will it follow a depth between the lines? I know its nothing as detailed as a navionics chip i have which i think shows every 1" depth line. Wondering if I would also need to get a newer lakemaster chip for better function? I read that it might work better on the maps I scanned on autochart. I have never been in a boat when its used but had a friend tell me in its early days a few times the troller would "get confused" about where to find the depth it was on sometimes and spin around in circles. Does that still happen on newer models too? Thanks in advance for any input on this. [/QUOTE]
