I just bought a HDS 5 Lowrance Insight to replace my X97-(which worked outstanding by the way). I wanted to get a GPS/Sonar system to replace my etrex for waypoints and tracking of trolling. My old unit's transducer had a temp sensor on the back and had a wheel for speed that fed in with the sonar acble together. The HDS mentions both of these items in their setup, but I can't tell if it has a temp unit in the transducer. I had also assumed that since the HDS is a GPS-tha it would show speed. Can anyone tell me if the HDS does either without external xtras? I'm not so much for temp as I am for trolling speed. Any help would be appreciated.
Thanks,
Mike
