Bizer Chart for Garmin Handheld GPS ?
 

I know theres already a similiar thread but I didnt want to Hi-jack it with my own questions. I have been thinking of buying the Bizer SD card for my handheld Garmin GPS map 60CSX. Is anyone familiar with it? I was hoping to use it as an aid for traveling the lake at night. I have been camping on the lake for 15 years and I feel like I know it fairly well however I have always been pretty nervous about traveling the lake at night. I was hoping this would help greatly. Thoughts?
