The one thing I loved about my lcx 28chd was that the tracking was so smooth. The arrow was always correct in accordance to my boat and when I would anchor over a piece the tracking movement was so smooth. Now that I have the hds, the track movement is so jerky.....is ther a way to make the tracking smoother.....?? Thanks guys

see if this helps

The GPS refresh rates on Lowrance HDS units come from the factory with a default �auto� setting. This auto setting adjusts the GPS refresh rate based on your speed. Some settings work pretty well from the factory, but this is not one of them. If you�re speeding down the lake, the refresh rate is fast. If you�re idling slowly down a ledge, the refresh rate is very slow and does not update the micro movements. This causes serious update delays� causing your unit to live in the past. If precise boat positioning is important to you � and it should be � you want real time updates.

The best way to get around these slow refresh rates is by going into the �Waypoints, Routes, and Trails menu.

1) Press �Page�

2) Press the right arrow on the cursor pad to scroll over to �Waypoints, Routes and Trails�

3) Use the arrows to select �trails� and hit the �menu� button.

4) Use the cursor pad to highlight settings, then press the enter button

5) Change the �logging type� to �Time�

6) Finally, set the time to �1 sec�. Press close and exit out.

That's good to know.
