First map review

"I got a chance to try Doctor Sonar's new mapping card this weekend. This card is amazing. The area pictured here, I have attempted to fish several times. I never could fish it due to the amount of underbrush. On all other maps this area is one color and just reads SHALLOW. I was able to follow the old channel that is clear of underbrush, and was able fish my way between the brush. When I was out of the channel, I knew it because I snagged up quickly. This new mapping card has enabled me to fish areas in the past that I had given up on. Also I traveled over 190 miles on Lake Oahe this weekend and was amazed how the trees and channel hold true 100% to the map. This will be putting more fish in my boat this summer. "Get the Net" "
