Height measurements

This sensor measures the height over the bottom. That is the distance from the bottom and up to wherever the sensor is physically located. This measurement provides you with a valuable range of applications for bottom and pelagic trawling.

Bottom trawl

Place the height sensor behind the headrope, and it will tell you the height of the trawl opening. This allows you to adjust you equipment immediately if the opening is reduced, and you will avoid loosing catch.

Pelagic trawl

With a height sensor behind the footrope you will know at once if the trawl sinks closer to the bottom. If you use a second sensor behind the headrope, the difference between the two height measurements will give you the vertical height of the trawl opening.
