Humminbird Down Imaging Mounted Sideways? Sidescan??

32 posts in this topic

Yes, each conductor has a shield and this particular one may have the shield under the outer insulation also. I haven't cut insulation to see. Just mashing the cable increases RF interference sometimes.

I didn't consider your comment as being a smartaxx. Actually an accurate statement and may be of some benefit to someone with a similar issue.

Yes, I have been continued with this experiment. It is very useful to look for submerged large objects (from 3-4 meter length) placed on big area, such as single tree, stones.

Maximum range is limited by 240 ft to ONE side(see Max. Depth adjustment). If you want more details or ability to see smaller objects like fish you should decrease Max. Depth. This model does not have Zoom function, nevertheless you can get "Zoom" using Upper Range and Lower Range of X-press menu.

I rarely take camera on boat. My boat slips badly on the ice river smiley.gif so, Waiting for a new season. Then new photos and videos will appear.

P.S. I often fish at twilight and adjust Light (Brightness) 5-7. When I off the unit and on again, Light level is 10 (default). It is not comfortable:(.

Great to hear. I was thinking about mounting it at an angle on my trolling motor so that I could swivel and "Look" around. I am a fisherman and think being able to see the structure from a distance and not driving directly over it and disturbing the fish would be better.

Question

If you scan a submerged tree say 50 feet away does it look like a tree? What I'm asking is the image good in your opinion?

Large tree looks like tree lying on the bottom up to 150ft from boat at 30ft depth. The image is quite good.

Another guy that does search and rescue says that they turn Down Imaging to the side to look under docks and underwater cutouts in banks for bodies and the images are pretty good.

Clint, I understand your thinking.

Yesterday I asked an individual at a local tackle shop that sells the Lowrance and Hummingbird units your query and he said that turning the transducer to the side would not work.

True or false, that is what he told me.

Have you ever heard of Wilson Frazier, the Professor of Sonar GPS?

Wilson has a series of three DVDs about sonar and GPS units. I suggest you consider investing in Sonar GPS 101 and then add the 202 and 303 videos. You will learn a lot about how sonar works and what you can do with your units.

The DVDs are produced by 2advise Productions at www.2adviseproductions.com.

You may also try to find Wilson Frazier on the Internet at Frazier Marine Group.

Frazier will be at the Richmond Fishing Expo and if I can catch up with him I will ask him your question.

I will let you know what he says if I can ask the question.

"Yesterday I asked an individual at a local tackle shop that sells the Lowrance and Hummingbird units your query and he said that turning the transducer to the side would not work."

Obviously that person knows nothing about the imaging technology. Selling those products vs. owning and operating those products are two different things.

Thanks for the suggestions Sam. I will check those videos out.

I think I have a pretty good idea of how sonar works, that is why I think it will work. The unit has no idea or care where it is pointed as long as it is in water

The guy from the other forum says that it works really well. He has his fixed at a 30 degree angle on the transom.

This just started as a idea, but wow, I never thought I would get this much feedback. I'll definitely give it a try in the spring.
