1 If a water speed sensor is not present, a less-accurate reading can be calculated using a GPS antenna instead.
2 If a water speed sensor is not present, a less-accurate reading can be calculated using a GPS antenna instead.
3 If a water speed sensor is not present, a less-accurate reading can be calculated using a GPS antenna instead.
4 If a water speed sensor is not present, a less-accurate reading can be calculated using a GPS antenna instead.
5 If a water speed sensor is not present, a less-accurate reading can be calculated using a GPS antenna instead.
