Sperry Marine ANS244 Speed Indicator -5 to 30kn

Specifications:

Part: ANS244 / Alt. 44773-07

Manufacturer: Sperry Marine by Northrop Grumman

Type: Speed Indicator Dial - Knots


Usage:
The speeds of vessels relative to the fluids in which they travel (boat speeds and air speeds) are measured in knots.

For consistency, the speeds of navigational fluids (tidal streams, river currents and wind speeds) are also measured in knots.

Thus, speed over the ground (SOG) (ground speed (GS) in aircraft) and rate of progress towards a distant point ("velocity made good", VMG) are also given in knots.

Used. Please see photos of actual item.
