Last Friday I attended the Doctor Sonar class that was to cover Lowrance, Huminbird Electronics and Navionics Mapping Chips and Apps.
The first thing Doctor Sonar aka Bruce "Doc" Sampson said to our group was "You'll have too much information at the end of the day". Yeah, he was right. I seldom take notes, but there is no way a person can retain all the information from this class without recording it or taking notes.
The goal of Doc's classes are to help us understand how we can make this technology work for us. After all, we spent the money on these units to help us catch more fish right?
Doc utilizes the latest in technology as well. If we had a question, we just spoke into a voice activated microphone and it was transmitted right into Doc's little hearing aid looking receiver. No matter where the student was in the room, Doc heard the question, repeated it and gave the answer.
The Power Point presentation started off with the basics to ensure we were all on the same page as far as understanding how the "2 D" sonar we are all use to worked.
Then it was on to figuring out what the heck all those different colors and marks were on the display. Now anyone can tell just by reading the owners manual that the color yellow is the most dense return, then red followed by blue.
What Doc does to help translate the colors in our brains is to show the display and the actual underwater video at the same time. Watching the bottom change from the blue (soft) bottom into a yellow (hard rock) bottom really help a person understand what your expensive electronics are showing the user.
Doc used the underwater video camera to show what bait fish, walleyes, suckers and sunfish look like on the sonar screen. Of course you'll still have to know the hang outs of these types of fish because your sonar will not label them for you. Confused? Here's one good example.
