2014 TROPHY BLUEGILL QUEST

[Slip Sinker]

My Master Angler quest for a 10 inch plus northern strain gill in Michigan continues in 2014...

Man, I envy the time you rich, retired guys have for fishing!

yesterday partly cloudy and a breeze so i made a beeline to one of my favorite spots to see if the weeds have cleared. looked on accuweather minutecast and i had about an two hours to fish before rain. caught many gills and three chunks two 9 in class gills and a 8 in class seed. drop shotting the 1 in gulp chartreuse minnow. this area was a deep tight inside turn in a weedline.

My wife agrees with me, I might add.
When I showed her your pics, she made that face... You know, when they think a guy is attractive, but aren't going to say it aloud.

Hahahaha

haha Dave

ive been told i look like a younger Al Lindner. 

yes its a great tool. what about side imaging 300 ft on both sides of your boat... now thats truly incredible...still cant afford it though. one day it will become affordable.

[David, aka, "McScruff"]

... and dammit you STILL look like a movie star, even after a day of fishing.

Congrats on the payoff - I love it when a plan comes together.

And a great explanation of what I already suspected. That unit of yours is truly a miracle, isnt it?

[Slip Sinker]

so my game plan paid off big time ... no lunkers over 9 or trophy 10 inchers but over 30 gills in my slot of 6.5 to 8 inch eaters. nothing was caught under 6.5 inches. i hit the largest weed pockets in the largest weedy flats in the lake drop shotting a Berkley Gulp hellgramite.

So in an extremely condensed version of this technology… the data received from the transducer as you are making these organized tracks with your boat, are processed in log files. These log files contain bottom depth, bottom composition and vegetation or weed beds set to gps cords. These log files are then processed and maps are then created. The maps come in three versions, contours only contours and vegetation layer and contours and bottom composition layer.    

The green is only one shade… the yellow contour lines are so close at one ft intervals it only appears as a shade of green.

tracks for the map creation i made are shown below.

PS Also of interest are the different colors. This suggests different densities of vegetation, which could be had from a thermal detector.... but probaly not from a camera.

It points to your system doing the data collection (you in your boat), and it being overlapped on the map.

[David, aka, "McScruff"]

I understand the concept behind sonar, so I think I was being unclear with my question.

What I'm wondering is how the vegetation layer is derived.

1. Did you do it by tracking back and forth across the subject area?

2. Did Insight do it using some sort of overhead imaging (satellite, etc.), and then it overlays it on your plotted map?
