Thats a good looking lab. I have a friend that has 2 white labs, they are both stark white. one is about 150lbs his name is moose and the females name martha. she's not very big maybe 60lbs. both ae great dogs, he trained them to be duck hunting dogs. maybe some day I'll get into water fowl hunting and get me a good dog and train it up.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
