As we don't really know how Spearfish III trolls for trout ... We can't be sure if the sock is moving away from the xducer (maybe sinking with no float)... or the xducer is moving away from the sock (as the boat turns)...

We can be sure that the distance between the xducer and the sock is changing ...
