I have a lowrance hook 7 fish finder and don’t under stand it .. it shows fish on it at different depths ..I guess. I just don’t know how to use it. I only use the gps , depth and way points on it . I want to learn how to use it for crappie and bass fishing. I’ve been to bass pro shop and they couldn’t help me just wanted to sale me a 1000$ different one . Can someone please help me with this.
How do you have it set ?? DI -- DI/2d -- 2d ??
Since I got Livescope I use my Hook 7 primarily for mapping/waypoints ... but, before getting LS I used it on DI only, and it did a pretty good job. When I used the DI/2d overlay it gobbed up the screen with too much "stuff".
Understand that the DI ping is a thin line spread to both sides of the transducer at an angle directly related to whether you're using 455kHz or 800kHz, and it's best picture is going to be when you're moving forward at a nice pace. "Fish" are going to show up as little "dots".
Here's some DI images to show you what to look for : (note: these are from my Elite 5DSI, not my Hook 7)

The "dots" around the log above are fish.
Attachment 439251
The "dots" around this log above are fish.
Attachment 439252
There are no fish seen on this downed tree above, and all the "dots" seen in the water column are likely just submerged particles/trash.
Here's what I mean by the DI ping being a thin line ....

The yellow area is the coverage area that DI shows .... the red area is the 2d coverage area. The "areas" shown by the two different colors are "bottom coverage". The 2d ping is a circular cone, so its a narrow area shallow & expands as it goes deeper. The DI ping is angled wider, but a thinner spread of coverage ... but also shows much greater detail.
455khz vs 800kHz :
A 455kHz cone angle has a greater coverage under water but will return an image with less definition. This is beneficial when scouting new country for the first time. An 800kHz cone angle will get a narrower coverage but with greater detail.

Thank you for answering.. how do I know if it is on d1 or d2.. I’m pretty much stupid on this thing .Quote:

Not exactly sure what you mean by d1 or d2 ...... DI (down image) has no #1 or #2Quote:

[QUOTE=Cashman;4303443]If that's "exactly" what you see, then there may be something wrong with the unit. I'm referring to the wide white columns and the blue/white checkerboard pattern I see in that picture. May be the camera's fault, but if not and those "things" are always a part of what's showing on the screen .... then you might want to contact Lowrance and see what they say could be causing them.Quote:

From the picture it looks like you have some other setting other than just Down Image on your Hook. I don't remember individual depth markings on "fish" with just the straight Down Image setting. That's with "Fish ID" turned on and would likely only occur if 2d sonar is being used (& not DI) or you have the 2d Overlay setting on your unit (combination of 2d and DI screen info).
[QUOTE=CrappiePappy;4303474]I guess what I’m saying is if there is that many fish under boat I just need a dip net and I would have a limit. Lol.. the gps,depth ,speed everything else works fine.. I just don’t understand what I’m looking at.. it shows fish and different size fish at different depths but I can honestly say I’ve never caught one using it..I mean I don’t understand how it can pick up fish going 10mph and then go 35 and the fish on screen don’t move with the speed of boat.. it all seems crazy to me and it drives me crazy.. cause I know the crappie are out in the middle of Kissimmee and I can’t find them.. but when they move into pads it is on ..thank you very much for your help.Quote:

First, read your owner's manual completely and learn what all the settings are and how to change them. Next, search Youtube videos for information on your exact unit. There are bound to be tutorials there that will help. Then, re-set factory settings, Youtube again, and change color palette to blue as others have said. If all that fails, contact Lowrance or your local Lowrance factory authorized repair shop and get unit looked at. Good Luck with it. It takes a while to learn any new electronics but it can be mastered.
I think you're mis-interpreting DI as D1; DI is short for "down imaging", not D with the numeral #1. The pictures you show above are what is commonly referred to as "2D"; I've always thought it meant "2 dimensional". It is the standard sonar view for nearly all makes of finders. These are 2 different ways to show the same information.
Crappie Pappy's first 3 pictures seems to be the DI view, not the standard 2D view that you're showing. Hopefully, that will get you a bit clearer on what the 2 views look like.
I'm not familiar with your unit but surely there must be Youtube videos on how to adjust it and ongoing explanations that should help understand what the adjustments are changing, as HappyCaster mentions above. Does it have a demo mode that you can play with when you're not out fishing? I found that helped me a lot when I was just starting out. I use Humminbird units, that's why I'm not up on exactly how your unit operates. Printed owners manual should also have explanations.
Edit to add: A quick Youtube search for Hook 7 Lowrance gives a couple basic videos right off the bat. You might also watch some "sonar for dummies" which does a good job of explaining things as well. Might not match exactly to your unit but will still be worth a look-see.
[QUOTE=Cashman;4303491]Everything you see on the screen (at any speed) is just "history", except for what is coming up on the far right edge of the screen. That's what the sonar ping is "seeing" at that moment.Quote:

Now, as far as seeing all those potential "fish", and not catching any of them .... remember, your depth finder is only a tool to show you what's within the ping of the sonar. It's not going to make them bite, or jump in the boat, just because you found out where they are. Believe me, Livescope has taught me that and humbled me in the process. :biggrin
I took several screenshots on my old E5DSI, and showed you most of them. But, to be honest, I don't remember catching any of the fish shown in those pics. :Doh: So don't feel bad about not catching what you see, just keep using your Hook to locate the cover and the fish (that's all they're designed for) .... you will eventually understand more about what you're seeing, and how to react with the proper method to lure them into biting your offerings.
Luck2ya in your adventures !!
Chart speed will change the speed at which your history passes to the left. The faster you're traveling, the faster your chart speed needs to be. That may be why you're seeing that big bunch of fish stay under your boat after you've moved a good distance.

Try this video from youtube. Hope that helps you it has 6 videos in one place to explain sonar. Sorry for the title it's not my video
Those are good videos to learn from.
I thought I might add to the Hook7 questions. I have recently purchased a boat with the Hook 7 on the console. Having always run Humminbird units, I struggle with the Lowrance. On my Humminbird 899 I always had a line that would show the channel. With the Hook 7 all I have is cookie trails from the previous owner. I’m fine in water I know but get real nervous elsewhere. I have spent quite a bit of time trying to see if there is an option to show the channel on the Lowrance and can’t find it. I have also installed a Lowrance compatible Navionics chip I had at home with no luck.
Am I missing something.
If not I also have a Garmin unit that is the same size I could switch out if that might help. This won’t work with Livescope but I already have that up front.

I haven't been out to check mine . The hook itself will only have base maps, but I thought it showed channels and channel markers.
