the owners manual doesn't say how to adjust the factory depth sounder on my boat. its the little two inch round digital one. it came set at five feet for shallow setting, off on the deep setting, and set at a -2. can anyone fill me in on how it should be set?

ok, anyone know who manufacturers it so i could call and ask them? phone number for searay's Baja tech line?

Does it have two buttons on the front, a down arrow and an up arrow?

It has three. Up and down arrow buttons and a "set" button inbetween them.

It's made by Humminbird. Should be an HDR 610.

Awesome! Thank you big time!

I've got the Humminbird owners manual at home. Let me know if you don't find what you're looking for and I can FAX you a copy of the manual....it has instructions in there.

mr ortega at livorsi just emailed me the complete pdf file on it. big thanks to him also for helping me out too

Never mind, found it on the humminbird website
