Thread: Confused

This is a few pix I got playing around the other day I wonder what the cross thing is

Because the 455kHz is 180° coverage to the surface on both sides...it is best for finding suspended fish out to sides where the upper reaches of the beams can catch the suspended fish...the trade-off for 455kHz is that the image will be a little fuzzier...

Conversely...because the 800kHz is higher frequency.....it is best for discerning detail in targets closer to the boat....the trade-off for the 800kHz is that the SI image will be darker out to the sides of the images...

Here are 2 shots of the same structure with the only setting difference is frequency choice...

Notice the 455kHz is brighter out to the edge of the display...but fuzzier...
Notice the 800kHz is more detailed closer to the boat...but darker out to the sides...



Use the 455kHz for finding stuff all the way to the edges of the SI Range you have set....then set a waypoint on it...

Reposition the boat to rescan the waypoint with the 800kHz to see what it really looks like...

look at the picture thats using the 800khz above that rickie has posted.see how dark the bottom return is close to the boat.now look at the concrete structure thats in that shot.it shows very well but if the structure in that shot was made of wood it would not show very good at all.now look at this picture that i took.im using the 800khz.this is wood and it shows pretty good.now look at the si view. see how bright the bottom shows close to the boat.

Im guessing that you've reading slabbacks thread about using a dedicated di transducer.if you want the best di thats possible for your unit you could use a di transducer and your si along with a transducer switch to toggle between the to.this would give you the best from both without giving up one.i no of no one that has had any problems with this type of setup but humminbird will not cover your unit under warrinty if you do this.

So basically if I see something of interest mark it , ride over it at different angles change my setting to see what gets me the best result. I think im just lazy and looking for a quick setting . If im playing around on top of brush when will I have time to feed them all these minners I got in my bucket. I love seeing these pix and want to get the most out of my unit . I know you guys have years of experience playing and adjusting your units and its going to take time for me to get use to mine . I want all the info I can get . Thanks for the info and keep the tips coming . The pix I see are some great shots.

no not exactly.were i fish i can pretty much set my unit on the di setting to chart scroll speed 5 sensitivity 12 and contrast 7 using the 455khz.that pretty much covers water from 5 ft. To 30 with just turning the sensitivity up a little on the deep side and down a litle on the shallow side.i dont ever run over stuff in different angles.when run over from one angle thats enough for me.i think rickie was offering a sugestion of running over marked structure from different angles to help you get formiliar with your unit....i think i spelled that wrong......

This is correct Don...

The dedicated DI xducer's have ...:

*1 round disk 2d piezo that will vibrate at 2 separate frequencies...and...
*1 long rectangular "down-pointing" piezo that will vibrate at 2 separate frequencies...

Not complaining or bashing, just trying to understand

I'm playing catch-up because you guys been busy while I was away makin da cover holdits...

No problem at all Don...it's very confusing with all the different models and technologies...then throw into the mix the experimental xducer setups too...

Any HB unit that the model name ends in x97, x98, or x99 will be a SI unit (capable of "computer generated" DI images from the SI crystals)...the xducer's for these models will always have 1 round disk 2d piezo and 2 rectangular "side-pointing" piezoes...(NO "down-pointing" piezo)...

Any HB unit that the model name ends in x57, x58, or x59 will be a "dedicated DI unit"...the xducer's for these models will always have 1 round disk 2d piezo and 1 rectangular "down-pointing" piezo....(NO "side-pointing" piezoes)...

Neither of the 2 different technology xducer's (SI xducer's or dedicated DI xducer's)...are blessed by HB to use on the other technology based unit...(they are just not made for that)...

Does HB know what we are experimenting with...??....absolutely...
Will our experiments ever come to fruition in a new product...??...only HB knows...

I just can't leave stuff alone when I have so many experiments I want to try make this 1197 do...

This is dependent on what you need your unit to do for you....

If you use your SI unit for mainly finding and marking new structure out to the sides of the boat path...SI is the berries....therefore, DI may not be that important to you....

If your a vertical jigger or drop-shotter...then better DI images would be valuable for picking apart structure and seeing the fish echoes mixed in with the brush...

If you want both...you can buy a dedicated DI unit and (if it's a HB Ethernet model DI unit)...link it to your HB SI unit...

If you want both ...and you don't mind experimenting and you don't need your warranty....you can do as kosmo suggested and get the HB TS3 switch and a dedicated DI xducer and switch between the 2 (HDSI xducer and DI xducer)...depending on what you need to see at the time...

Some in the discussion have said that there is just not that much better DI images with the dedicated DI xducer on the HB SI unit.....I guess that's going to be in the eyes of the beholder...

You tell me...

This is brush with "DI from SI" on my 1197...



This is the exact same brush with a dedicated DI xducer thru the HB TS3 switch on my 1197...
