Thread: Need a little help......

The horizontal black lines (that are not indicative of structure shadows) are usually a sign of turbulent aerated water flowing across the face of the xducer...

If we eliminate this issue...your pix are actually pretty good...

Can you post pix of your xducer installation ...??

I personally dont think the images are too bad. Are these pics of your screenshots, or been uploaded to computer and then enhanced? Can probably get a little more detail with increasing image size, and ya can do that by just setting the screen to show just one side of the boat at a time. Also switch between pallets to determine which color shows the most detail. Outside light can cause the need for a different color pallet each trip out. When ya stop the screen on something then you can experiment with these different pallets and settings to get the optimum image. Great shots man, keep em coming. I love these kinds of threads!

Learned something new again Rickie! I would have thought the lines were RF interference.

I can, but the transducer is mounted in a way to catch turbulent water coming from under the boat. I actually have it mounted on a "temporary" mount. I can experiment this way until I find the optimum place for the transducer and then mount it permanently. I will adjust the mount and get the lines out that are not part of the structure. That will probably take care of my poor screens at speeds above 3.5 mph.

I'll be back on the water near the end of the week and post some results after the changes.

I appreciate the quick feedback. This SI is exciting and fun. I have already found I can burn up a lot of gas riding around "looking" at stuff.

OOOOOHH but ain't it fun!!!!!

good shots, keep them coming after ya get the mount in.

Black horizontal lines are usually aerated water (bubbles blocking minuscule sections of the sound pulse)...


Light colored horizontal bands (of a lighter color of the same Pallete color)..are usually TM interference...


"Sprites" on the SI image are usually crosstalk from another unit or just errant RFI...


Note I use the word "usually" in all instances above...

THATS GOOD RICKIE,GOOD INFORMATION,ARKCRAPPIE,GET THAT DUCER CORRECTED AND YOU WILL HAVE IT

Thanks for the excellent tutorial Rickie!
