Locating Humps with the Lowrance HDS Sonar GPS Unit
Humps are productive locations for finding and catching all species of game fish. There are two ways to locate them with a Lowrance HDS unit. One way is to locate the hump on the map before driving to it. The other is split screen the unit and watch for humps to appear on the GPS side. The two screenshots show how you can located humps using the Lowrance HDS unit. Read more about locating humps with sonar GPS units... Lowrance HDS Palette Color Choices
How do you change the color on the Lowrance HDS units and why does it matter? Would changing the Lowrance HDS unit’s color help me catch more fish? Doctor Sonar: The Lowrance HDS Unit has different palette choices which change the color of the screen. Read more on Lowrance HDS color choices... DownScan by Lowrance is it really that good!
DownScan is new technology from Lowrance which gives us a different view of what is below the boat than traditional sonar view. The images are crisper and look more like what is actually being seen. Read more on Lowrance DownScan with Doctor Sonar... |
Correct Transducer PLacement for High Speed Readings Doc Sonar,I just purchased a Ranger 620VS and have a Lowrance HDS 10 at the console and Lowrance HDS 5 on the bow. I am having problems with loosing bottom at speed over 10 mph. I took it back to the boat dealer and they put an external transducer mounted back by the drain plug to use instead of the thru-hull transducer. Well, my sonar unit I still have the same problem of not being able to read bottom when moving. I called the dealer and they said to turn up the ping speed as high as it goes, but that didn’t work so I called Lowrance and they told me the transducer was not mounted deep enough. Before this boat I had the same issue. Do you have any advice? Thanks, S.B. Read more about mounting a transducer... Adjusting the Lowrance HDS Window Choices and Resizing the HDS window screen

When you stop and think about how far Electronics have come it is just mind boggling. I was talking with my good friend Doug Vahrenberg and he asked me to do this article. He gave me some great photos of the old units of yesteryear which I have included. What in the world did we do before we had fishfinders like we have today? The Corps of Engineers started damming up large rivers creating "structure", but how did you find it out in the middle of the lake? I wanted to pass along this story Vahrenberg told me. "When I was displaying the old Humminbird graphs at a Sports show a man came up to me and told me how they found structure. They would drag an old window weight on a rope. When it would get slack in the line it was either a point or a hump. That's how they found structure in a lake. They said the slacker the line or farther it dragged behind the boat the shallower the hump. They said it made the difference as they were the first to fish offshore structure." Think how many hours or more like days, it took to learn the bottom with a window weight and string! Read more on the history of fishfinders... |
