@ HB Greg

Greg,
A couple of ? for you if you have the time,

First, I've noticed that my SI feature on the 998c always has the right side being brighter than the left. I'm assuming that I need to rotate the ducer clockwise a bit to correct this. Correct?

2d, I still have room on my machine for another ducer. Would it work, or be possible to install an HB dedicated DI transducer and have it function with as my DI for the 998c unit?

Last, if I get question no. 1 fixed, (the unit nice and flat) , is it likely that this will greatly improve my current DI quality? I may be essentially missing the target with the current DI set up?

thanks for all the help,

Rotating the transducer may help, yet it could also be the transducer itself or the installation that is the problem. Usually it is the installation where one side of the Si sonar gets partially blocked by something on the boat – but not always. Post some pictures of your transducer installation for us to look at. Include some from behind the boat, from the left side of the transom looking across the boat and from the right side of the transom looking left across the boat. All should be taken at the same height as the transducer is mounted.

I don’t know where you think you have room for another transducer (I assume you mean a connection on the unit) but there is not one. You can install a DI transducer and use a TS3 Transducer Switch to change back and forth from one transducer to the other if you would like. Rickie (rvinc) is doing some experimenting with this set up now. http://www.crappie.com/crappie/side-...rimenting.html

Hard to tell as I do not know what you are seeing on your current DI sonar.

Thanks,
good points to consider,
next time out I'm going to raise the motor a good bit to make sure its not in the way,
I also have a drain plug that is to the side and below to ducer. That may be interfering with it I suppose.
I did consider extending the ducer out from the transom to get it away from the drain plug.
Perhaps Ill now try that.

Temporarily mount the xducer to a stick and stick it down in the water way past anything on the boat and see if both sides even up in brightness...

This will tell you if something on the boat is partially blocking the SI beam...

so, you flip the switch and the di pops up? do you interpret the image you posted as fish on a brush pile? please take and post more pictures. a bunch of us are interested. whats your cost so far ? thanks

The view choices of the SI unit in these experimental xducer setups stay the same as come from the factory...the DI data is just coming from a different xducer...

Using the TS3 switch is for convenience switching between the stock XHS 9 HDSI 180 T xducer and the XNT 9 DI T (or the XTM 9 WIDE DI 20 T)....whichever is used in this setup...

Most of the details can be found here...with lots of sample pix...
Ehrler's use of XNT-9-DI-T transducer with 1198?

so far no cost to me other than i probably dont have a warranty anymore.http://i826.photobucket.com/albums/z...ps4e6970ac.png

I've only tried this one time so i don't have lot of picture's. .i wanted to show one that's got the fish arches on the 2d to compare to..this picture's the best that I've got for now . trying to fish and experiment at the same time.. you need to go to that link that rickie provided for the most info.. http://i826.photobucket.com/albums/z...psaacffd71.png

Cost of this would depend on which experimental xducer setup you would want to use...

The cheapest would be to just buy either the XNT 9 DI T (200/455KHz 2d) ...or the XTM 9 WIDE DI 20 T (83/200kHz 2d)...

Just plug the DI xducer into the unit with either of the above to get "Dedicated DI" views...(this eliminates SI tho)...

If you want to be able to still use the stock HDSI xducer for SI and use the DI xducer for "Dedicated DI" views...you would also need to buy the TS3 switch to select between the HDSI xducer (for SI) and the DI xducer (for DI)...

If you want to use the xducer setup of the HDSI rotated 60° to get "Dedicated DI" views...you would have to buy the AS SIDB Y cable and an additional HB xducer capable of 83/200kHz 2d....(this also eliminates SI because now your HDSI xducer is rotated 60° and not capable of the left side of the SI image)...
