The Montgomery Ward 7x35 mm binoculars featuring Bak-4 prisms were typically produced in the 1970s, although the exact year can vary based on specific models and production runs. Montgomery Ward sold various optical products during this time, and Bak-4 prisms became a popular choice for better light transmission and image clarity. For precise dating, it would be helpful to refer to the specific model number or any identifying marks on the binoculars themselves.
What bright planet is often thought to be a UFO?
Mars, Venus, Jupiter, Saturn, all of these are Bright Planets that are visible to the naked eye in the right situations of lighting, clarity of the sky etc. I once and only once saw Saturn through 7x35 Binoculars through an apartment window- it was quite impressive with the rings. Of course any experienced star gazer would see these objects as Planets and not moving vehicles!

Why is 7x50 better than 7x35 binoculars?
The 7 is the magnification produced - it is a ratio of the focal lengths of the lens at the eyepiece and the front (objective) lens. The 50 is width of the objective lens - in millimetres.
What is the best type of binoculars at the cheapest price?
Good binoculars for hunting should be waterproof, 7x35 (for the best light-gathering for their size), center-focusing, long eye relief if you wear glasses, and have one adjustable eyepiece so that they can be adjusted to your personal setting for your vision. You should be able to pick up a pair meeting those specifications online for between $100 and $200.We do not recommend anything less for hunting. It doesn't make much sense to buy a cheap pair that will have to be replaced the first time you're caught in the rain. Nor does it make sense to invest hundreds of dollars in other equipment, but get cheap on the piece that will make it possible to find game. A decent pair of binoculars will cost twice as much as a poor pair, and will last a lifetime. The cheaper glasses may not make it 100 yds from the truck.
