Thanks Johnny.
I would most certainly like to utilize my Transducers to give me the depth information but there have been ongoing problems with accomplishing that goal. It started with a DFF-3 with a R309 transducer vintage 2013. I would consistently lose my depth readings on my TZT14's. Had the DFF-3 serviced. No difference. Everyone pointed at the depth sensor on the R309. Decided to fix the problem by upgrading to a DFF-3D with a 165T? and add a DFF-1UHD with a R599 instead of my R309. No difference. Did find out that with my DFF-3D, if I set my range much deeper than my depth, depth info will not show. As an example, cross the channel with the range set to 600 ft and when I get to the island, a depth of 40 ft doesn't show up. Just some anomaly that if the range on the DFF-3D is too large for the current depth, there is no output on the depth indicator on the TZT14 if the preference is set to DFF-3D. I haven't done the same with my DFF-1UHD, so I will check. My initial solution was to just set my navigation depth on the TZT14 to the DST800. That way I can monitor navigation depth all the time. But as I said, the TZT preference will then jump to the DFF-3D and unless I have the DFF-3D in the proper range for the depth I am currently in, I have no indicator of depth. Bart took pictures of the DFF-3D issue. I thought I had a work around, but since I cannot lock in the preference of which sensor to use, I am still fighting the problem.
