Sharpness takes away from crisp shots but much better results at slower speeds...thx kosmo
Noticed the fish at the bottom edge of the bed and a small group just inside. Anchored off and fished those two spots and got some keepers.
What did you have unit set on?
sharpness was set on low to see the fish, scroll speed was on 3 i think...will have to check. Had the 898 on the console recording and was setting on the TM making passes at about 1-1.5 in that cove. Had the 898 turned so I could see it. I'll check the recording and get some better details for ya.
----------------------
Isn't their a way to use the recording to change setting to fine tune it or is that a snap shot?
genec had brought up a good Q in another post...why is my depth reading showing deeper than my SI shows?
Sounds like a question for RickieQuote:

Nice shot slabbacks,I think you've mentioned that your si transducer is mounted on your trolling motor.if it is you can scan to find those beds but you can also use your trolling motor to scan out in front for more beds.it will keep you from running over those other beds that are always there,that are close to the big beds that you find.give it a try the next your scanning,just keep your boat moving just a little bit and stop running the trolling motor,then slowly turn it.you may get a big surprise of what you will see out in frontQuote:

Do you have your "Depth Offset" setting different from default "0"...??
Rickie
My 998 will often read 2x actural depth on a hard, shallow bottom..... must be a difference how SS gets depth vs the 200KZ depth.

cache I thought the depth reading was taken from a different part of the tx. dont know all the technical terms for it lolQuote:

thx rnvinc
COOL picture of those beds! I have a question about using SI. I am still kicking around getting a new SI to replace my DI. I have noticed that hardly anyone post SI images using "Contour View" taking out the water column. Is there a reason you guys do not like this setting? I would think that it would be MUCH easier to interpret what you are seeing without the water column, especially when looking for contour breaks in deeper creeks and channels.
There is interesting history behind the "Contour" feature....Quote:

Then after HB finally introduced the "Contour Off" feature....very few even use it...
I think during those 6 years ...users realized there is valuable information in that "dark water column"....and shutting off the "dark water column" hides that information...
Rickie
Rickie hit it on the head, I like the water column to show for a couple of reasons. At a glance I can tell what the bottom is doing and this really helps in the skinny water. yes I can just use depth reading at that spot but having the trail is just something I prefer better. Also I like it in deeper water due to the information it gives you on whats under the boat when it comes to fish in the water column and or structure.
I started with a DI unit but with the cone it shoots you have to cover a lot of water to get an idea of what's in the area not to mention in shallow water you have to run over or very close to check it out. (spooking the fish). SI covering 75-100, 1 or 2 passes and I know what's there and if I want to take a better look at something. I mark them with a waypoint, bring in the view and re-scan to see if it's worth dropping a jig.
Don't get me wrong. DI units are great and will put you on fish with some very detailed images. Just ask yourself what you need and how you like to fish. good luck
Get both, they are invaluable IMO
I fish all of the time and (imo) ive got the best di unit going between humminbird,lowrance, and garmin and I still believe that di's primary use is playing.it helps very little fishing and acually waist time.the only thing that I'm seeing that might be helpful would be if churp could be added to foward looking sonar in future.(its already being used in more expensive units)Quote:

EXACTLY the way I see it... SI/2DQuote:

:Rofl ... I'm just the opposite of some of you guys !!
I don't have, nor do I miss having the "finger paint" images of 2d sonar ... and the guessing game that goes along with trying to figure out what it is that I'm actually seeing on the screen.
My little 2d HB unit on the console is used for depth only, when idling, running, or launching/trailering the boat. My DSI unit is on the TM, where I am when fishing, and gives me GPS/Chartplotter capabilities while also showing me a "picture like" image of what I'm running over. I have little doubt of what I'm seeing on the screen, so no guessing or "interpretation" is needed. :biggrin
... cp :kewl
gene, I thought we didn't stop if we didn't see them on SI...:yikesQuote:

Sorry, I was off Monday and had to deal with a assembling and testing a new grill and also had a flat tire - which I got on the way to buy the new grill… the good news is the ribs and grilled corn were excellent!
I’m not sure what is going on with this guys. The Depth Offset menu setting should change where the lake bottom is graphed in all three sonar types (2D, Si and Di). I can’t think of any menu setting that could cause this. If the cursor was activated the water depth could change but the displayed sonar wouldn’t but we should also see the cursor on the display (which I don’t). So I guess I’m not help after all!
Good to hear about the ribs and corn...bad on the tire Greg.
To me it's not that big of deal. The thing just puts me on fish time and time again...dont get much better than that. went out today with a friend and this was the result. enough said :biggrin

Maybe there is a possibility that the Depth Offset setting only affects the "Digital Depth number displayed" and nothing else...whereas the distance from the xducer to the bottom is at 6ft...with a Depth Offset setting of +1.1 would simply display the real distance (6ft) + Depth Offset (1.1ft) for "displayed Depth" of 7.1...Quote:

I wonder if there's a way we can test this...??
Greg...can you pick the engineer's brains again...??
Rickie
I can try Rickie but I played with the Depth Offset menu with a 998 unit running in the Simulator mode and it changed the digital depth readout AND the distance the bottom was shown to the surface/zero line in all three sonars (2D, Si and Di).
Now I see what you are talking about. I'll change mine over to default off set and see if the readings change as well.
I need to try this on my 1197 on the water and see what happens also...Quote:
