Map Review
I have been using the Doctor Sonar chips for the last few years on a daily bases for both tournaments and even more importantly as a full time guide. I have been guiding on upper lake Oahe for 25 yrs, so to say I know this area is a understatement. This being said, I learn new spots and find subtle pieces of structure all the time that put fish in my boat. I upgraded this year to the new chips and the detail and ability to zoom in and keep the color contours is huge. I don't write recommendations to any product that I don't use or believe in. I give the Doctor Sonar chips my full endorsement.
