The air pressure is more or less suitable for fishing.

990- 1005 hectopascals, which means high pressure is better for fishing. Generally, before the arrival of cold air, windy days and typhoons, the air pressure is relatively high, which is more suitable for fishing.

Low pressure weather, bad fish mouth, not suitable for fishing. Many people don't know that fishing is also related to air pressure. Pay attention to the following items when fishing: For fishing in spring, generally choose a portable pole of 5.4 or 6.3 meters and a thin line of 0.4 or 0.6.

Fishing barometer:

Atmospheric pressure affects the activity of fish. Under high pressure, the dissolved oxygen in the water is high, the activity of fish is high and the appetite is good. On the contrary, fish have low activity and poor appetite. If we know the change of air pressure, it will be of great help to improve the chance of catching fish.

The main functions of this product are air pressure measurement, altitude measurement, temperature measurement, N groups of fishing point data recording, fishing point water depth recording, fishing point air pressure recording, air pressure correction, weather forecast, 24-hour air pressure change chart display and time.
