The boat was listed as having no electronics, but when we had it surveyed, a GPS unit and a Humminbird 200 DX Fishfinder suddenly appeared. I have yet to work the plot setup for the GPS. Will that give me accurate speed? The fishfinder lists a temp and mph, but I'm not getting mph readings. No manuals came with this stuff, so the Internet is helping piece it together. The fishfinder has a second transducer, just a small round cylinder, so I'm worried it is only a temp sensor, but I was going to contact Humminbird this week to try and figure it out. It definitely shows fish, Friday we cruised to Sheldrake for dinner and at low speed it lighted up with fish in the 60-110 fot range.
