  1. That was a very nice video. As for size comparison it would be nice to know the size of something as we see dots or arches on the screen as to what size they really are. For instance you could have scanned Kyle below on 2d, DI and Side Scan to see how his size compared on the screen to how big he is. For we all wonder for the dots we see, how big is the fish, do the dots get bigger with bigger fish?

  2. Thanks for a great video. Really helps to put things into perspective. While looking at the detailed graph to the far right and far left, are their distance markers telling me how far and what direction is a group of a particular structure or group of rocks so I can head over to that area?

  3. Great video and showing comparisons of down, side imaging and traditional sonar.  We were using a Humminbird 797C2 with a 5" screen.  I wanted to upgrade to a bigger screen and new technology like recording maps.  We looked at the Humminbird Helix 9, 10 models at a store on display.  I noticed a big black border around the 9" screen.  Asked the sales guy what's with that.  He said 9" to 12" use the same case.  If you buy the 12" the screen is filled.  I told him I don't like that at all.  We ended up buying a Garmin with a 9" screen.  Pros has a lot of features, no limit to recording maps what ever your card will hold.  I purchased a lake map.  The unit comes with the marine maps.  I had to use an app to register after that it gave me the option to save to a SD card.  I took the 32 gb card out of my unit and saved to it.  Now I have everything on the SD card no switching cards.  Great feature.  Plus I made a backup card.  The original Lake Map is put away.  The Cons – I was not happy with the side imaging.  Really poor and very finicky, speed of boat has to be just right plus has to be moving.  The detail isn't even close to what my 2009 797C2 Humminbird does.  Garmin also states that side imaging is for structure only not finding fish.  I know salmon guides that use side imaging on rivers to figure out if fish are to the right or left of them.  Seems odd side imaging isn't for spotting fish.  I was told no Garmin side imaging is really good.  I don't see it.  While talking to Garmin support, which has been pretty good, I asked about enlarging the MPH on the screen so I can see it better from the back of the boat while trolling.  There is no way to change the size of the text on the screen.  I could hide some things but that was it.  I was told Humminbird is like a small block Chevy they just work.  Garmin I have been told is more of a pain with a lot of tinkering needed to get things to work right.  I have been messing with the transducer to get it right.  Never had to do that with the Humminbird.  Also can you recommend a Humminbird model in the 9" or 10", minus the big black border.  We are kicking around selling this Garmin and going back to Humminbird.

  4. I was really anticipating this video as I bought a Humminbird a few years ago & paid significantly more for down imaging. (Side imaging was just being introduced & way out of my price range.) I generally don't use the down imaging because it doesn't show anything. I go over a whole school of game fish on sonar & change to DI and there's absolutely nothing at all there – completely black screen. The only time I've ever seen anything in down imaging mode is when I run over a log or something else big, which I can tell on sonar. I feel that the down imaging is a gimmick and complete waste of money.

    You obviously have far more experience with it than I. Do you have any idea what I'm doing wrong?

  5. Great video.I'm a beginner with the 698ci HD SI unit.I would get more out of a it'll more basic stuff like explanation if the different Views available, which Views you were switching to and from, how to set display scale based on circumstances,..Also, where would you have thrown, in relation to the boat position, if you wanted to catch those 3-4 "walleye" you pointed out on the return?After your buddy, Kyle, dived in, he must have thrown a big return back. Where was he and why didn't you show us where he was on-screen and with respect to boat position?I need a lesson on how to read the different Views. I spend a lot of time switching Views without knowing which is giving me useful info for what I'm doing st the time.Thanks for the instruction.mgf

  6. Nice video. It would be nice to see how down imaging looks in a grassy lake. How pick out rocks in the weeds.

  7. Amazing tech. If you could just shoot an electrical shock down where you see fish, and have someone net them and put them straight into your live well, you could save the hassle of fishing altogether.

  8. Gentlemen, I want to use two similar humminbird fish-finder transducers as diver detection sonars. Because they have a shorter range than the actual diver detection sonar, I want to use them like security cameras (one next to the other) in order to cover a bigger area. I also want to combine their output to one TV screen just like security camera display. Is this possible? what do I need for this to happen?

  9. Love this video!  I've been frustrated over the last couple of years trying to get my Helix 9 to show screens like the videos show.  This was quite helpful but I have a question.  I assume that the sonar frequency setting plays a part….but that wasn't mentioned.  Any suggestions?
