Re: Fishfinder vs depth sensor


On the GPS units I have used (2 lowrance and 2 garmin) the gps speed readings are instantaneous. The lowrance responds faster, if the boat surfs down a wave the speed shows it right away. If the boat rolls in a swell, the speed can show that as well. The garmin is a little more damped, it responds to surfing a little slower and doesn't seem to respond to rolling.
