    Rick .... I know next to nothing about SI, other than what I've seen/read on here. But, even with that being said, it seems to me that you would get better images with a smaller span. Say, something around the 50' or 75' range ??

    Hey Rick...

    Are you using the stock XNT 9 SI 180 T "Compact SI" xducer that came with the 798 unit...??
    (This number should be printed on the xducer cable about 1ft up from the puck)

    It is possible to use the XHS 9 HDSI 180 T "Full size" SI xducer on your 798 and possibly get better images than the "Compact SI" xducer will give...

    This is because the crystal elements in the "Full size" SI xducer are physically longer....(longer elements make thinner SI beams which can give sharper SI images)...

    (If you decide to use the XHS 9 HDSI 180 T "Full size" SI xducer...realize the 455kHz beam will be the only one active as the 798 cannot process the 800kHz frequency)..

    Wilbur has a XHS 9 HDSI 180 T for sale in the classifieds....http://www.crappie.com/crappie/perso...hdsi-180t.html

    As already mention, i would slow chart speed to about 3 and boat speed to about 2 for a good detail pic,would change color to amb, and change to about 40 to 50 feet wide and if knew where i was looking would set to just one side on 798 for a better detail and also hit zoom ,all this is when you want a good detail of the object you want to see, i too have the 798

    thx for the replies and suggestions. i will defintly get the chart speed down. the xducer is factory that came in in box, the xnt model. i looked at that xducer wilbur has for sale. thats a really good price considering what HB wants for it alone. i've got a lot of learning to do w/ this si/di. but i did see a big difference in SIM MODE when i decreased the si down to 50 ft. i also adjusted max depth to 50 ft on 2d and di and they are showing alot better. it looks alot better quality and images are getting clearer. i need to get it to the lake for more testing, but too cold and the water is very muddy from all the rain. i just hope the RFI stays out once i put it in the water. thx again, rick
