Omeroruc,

Thank you for you inquiry. We need to have more details and explanation in order to help out. Just saying the unit does not work at night does not give us any way to help. Please post some photos of the sounder fishing in the day when it is working and photos at night when it does not appear to be finding bottom. We also need to know how you have the sounder set up? Gain, Clutter, TVG ect. Please provide as much detail as you can.

Omeroruc,
Thank you for your inquiry. I'm not sure if I understand the nature of the problem/question.
"I see rock sand everythink. But when i go to fish night......i try realy i dont see"
are you referring to not seeing the bottom discrimination mode on the GP1870F echo sounder? please be aware that the bottom discrimination mode is operable only between 16 - 328 ft and at less than 10 knts of speed.

Good afternoon Omeroruc,

Probably the best way is to upload the video to YouTube,

Then post a link that will take us to the video.

Kind Regards,
