how to choose binoculars for travel?

I believe that the best binoculars  www.atncorp.com/smart-hd-binocular  for travel and walking are lightweight binoculars. There is no pleasure in carrying a bulky and heavy optical instrument with you all the time. But for hunting and fishing, you should not choose the lightest and most compact binoculars. Still, an optical device for these purposes, first of all, must provide a good overview, be protected from bad weather and transmit a clear picture even in low light.
