I have a DFF 3 paired to an MFD 8 with a airmar R509lh tansducer. It holds the bottom out to about 500 fa then looses the bottom and I never seem to get the bottom reading back until I get back in "shallow" (50-60 fa). I was lead to believe this unit could see down to 10,000 ft.
My tap settings are on B for both high and low freq. The dip switches are set as from the factory compatable for MFD 8. Am I expecting too much from this unit? Any advice for settings? I have been running the unit in fishing mode. Also, the I believe the unit has selectable outputs of 1,2,3 kw and I am not sure where in the menu I adjust those from.
