Garmin DIY Contour Maps

[BURLEY]

I have been fishing places like Willard, Hyrum, Glendale, and the Snake River. My electronics came with basic mapping that didn't have contour lines for these waters. I read about Navionics mapping service, but I'm too cheap to pay the annual price and deal with storing data and sending it off and waiting to see what you actually recorded. I recently saw that Garmin had a Quickdraw Contour Mapping option that draws contour lines on YOUR map while you drive your boat. It stores map in a SD card and can be shared. Accurate mapping at up to 10 mph, but when I zoomed from North Willard to Island, it was still mapping at 20 mph. I recommend under 10.
I ordered and installed the Garmin echomap chirp plus 73SV . with the QuickDraw feature and Transducer. I took it out to Willard after lunch yesterday for it's first test. Turning on the app at the dock, I proceeded to map the bouy area at 7 mph before heading North to the outlet area. Still mapping I headed south at 20 mph to map the rock piles and the Island. At the Island I mapped at 8 mph . I used Tracks to help guide me. In about 23 feet of water, I would map an area out to 35 feet on either side, or a 70 foot swath with 1 foot contour lines with depth shading.
