2. Precautions for using bee-hunting binoculars:
① Distance and viewing angle
When using bee-hunting telescopes, it should be noted that 500 meters is a medium-to-long-distance observation, and it is necessary to magnify 8-12 times to see the details clearly. If the distance is very far, the minimum resolution angle of the human eye is about 1 minute (1/60 degree), and a 3 cm object can be seen at 100 meters. By similar proportion, 500 meters needs to be magnified about 10 times.
② Environmental factors
Bee activities are greatly affected by temperature and humidity. When using bee-hunting telescopes to find bees, you should choose the early morning or evening when the air transparency is high. The spring and summer seasons (March-May) and after rain are the best time to find nests, because bees are most active at this time and easier to find.
When using bee-hunting telescopes to find bees, you should give priority to searching in hidden places such as foothills, mountainsides, bushes, and caves facing north and south, and avoid open areas with strong winds. These places are more suitable as natural barriers for beehives.
Therefore, when choosing a bee telescope, you must choose one that is waterproof, dustproof, fogproof, non-slip, rainproof, and vibration-proof, so as to avoid the impact of many actual environmental factors.
