Livingston does have contours but those images are posted at the same zoom level you did and was done so consumers can compare the same level of data. Livingston is not HD yet but does have contour lines.

LakeMaster when a lake is HD is done to the best data that day...guess when you do it right the first time and capture the details as was suppose to be done you don't need to update as often. And LakeMaster when doing HD Scanning is using only their approved scan teams. There can tons of variables that can add inaccuracies using the general public...like how deep is the transducer in the water, are they getting good GPS REception, where the GPS Receiver is from the transducer and lake level the day they scanned. How are these variables over come? None of that was taken in account when I send recordings in..it was go get them. Then they didn't even use them. Guess I'll leave my mapping to the expert charter that LakeMaster uses. Also sounds like these updates are forever? Isn't it just one year on the updates then you have to pay again to extend? Why wasn't the data collected the first time?

Funny you don't want to help others compare Apple to Apples so they can make the best decision for themselves. Heck you pick the spots of HD Lakes booth brands have and I'm up for showing what LakeMaster has to offer from the current version 2 of Texas/Oklahoma Lakes. But lets look all over the lakes from the back of the creeks to main lake structure. Consumers deserve to see what they are getting. I'm just trying to give example of what they get with LakeMaster. Shouldn't they get the opportunity to see the same from Navionics. Both are great companies but there are differences in product. Let show them what their hard earned dollars are going towards and let them make the decision based on their needs and detail level.
