Thread: Humminbird 899

The black horizontal lines in the SI images are an indication of aerated water ... Bubbles blocking the sound pulse...

Slow the boat down or re-Positon the xducer into cleaner bubble free water...

I would suggest opening the SI Enhance menu and adjust the SI Sensitivity frequently as the bottom composition changes...higher Sensitivity to brighten image - lower Sensitivity to darken image...

Are you using the stock xducer that came with the 899...??

Rickie

These guys will get you on the right track. I HAD some of the same issues. Keep giving us some screen shots.

Rickie will get you on track!! I agree need to bump up the sensitivity to brighten the pics.

Yes using the 455 xducer that came with it. Do you guys think it is worth the upgrade?

I will play with the sens. this weekend and repost some pics. Is there anything else I should try?Any other setting that may not be obvious?

gooseslayer I traded the transducer that came with my 899 and I believe the picture quality is quite a bit better than with the compact side transducer that came with the unit. I also purchased a da'ducer from rickie and put my hi def transducer on the front of the boat and saw a world of difference in the quality of the image. The da'ducer got the hi def down below my troll motor and it is about a foot under water so no problem with interference from anything on the boat. I just mentally add a foot to the depth showing on the depth reading. I don't think you will be disappointed in getting a hi def or getting the da'ducer from Rickie. Has anyone that has a 899, 999 had the 800 khz problem fixed by sending theirs in to humminbird for repair. Was just wondering.

gooseslayer here are three pics of si on my 899. First one is with original transducer at 455 khs and the last two are with the hi def transducer at 455 khs.
