While fishing offshore this weekend my tzt 14 would not show me my drift speed while fishing. It will show my speed over 4kts while under way. the machine is running the latest software ver 4 and i did a clear on the machine after the update. I also did a reset on preferd data sources. before the update i was able to see my drift while fishing with no problems. whats the problem?
