Doctor Sonar Chips

Anyone ever use these? Sounds like Perch Patrol guys use them on Devil's Lake along with some tournament fishermen. Neat concept.

Overlays aerial photos of the lake from 1949, 1980, or 1990 with contours of lake elevation to get you started finding the "spot on the spot". You can see all the old roads, farmsteads, trees, etc. that are now underwater. Seems like you can then turn on your contours on your head unit and see lake depth overlaid.

I like to to get those Frito's Scoops, fill them with peanut butter then drizzle honey on the whole deal: It's good.

They are impressive chips.

There are some different options....side imaging, different years of overlay. Any insight into what a guy should start with or what the differences/benefits to variations are?

I have his chip for Sakakawea. Very good.

I’m no expert. I run bird graphs, so my only times with it has been in other boats, but I thought it was handy.

Most have ran these for the past 10 years plus. Zero secrets left.

I think they have value if you’re somewhere you’ve never spent much time on. A buddy had one for Sharpe and the old imagery is really good for fining the old trees. I feel the regular chips are just as good with standard contour mapping.

That's what I was thinking....I don't spend much time at all on Devil's Lake and it can be intimidating to try and dissect. Would at least help me find trees, rocks, roads, etc.

With a little time and work there is a way to use Google earth to make your own historical maps then send them to a Google map on your phone. Have done this for a handful over the years. Doesn't give depth so you need to go sample yourself but it has helped me find some interesting spots

I haven’t found pre flood imagery on Google for the Missouri River reservoirs. Am I missing it? That is what I found handy with the chips.
