I used to keep a pair of cheap nikon 10x56 in the car and used them very rarely. then I started watching, and seeking out birds during the pandemic. I bought a nicer pair of nikons (monarch 5 8x42) but would never leave them in the car. Now i've gone completely nuts and bought swarovski Els for my primary use and leave the monarchs in the car. Yesterday I stopped by a park for lunch and took a walk with my monarch 5s and started wondering if i need to upgrade my car binos, but, upgrading would likely conflict with two of my apparent criteria, a) inexpensive, b) lower tier and less-loved than my primary.
What are your criteria for binos you leave in the car, i.e., just in case you see something cool or decide to take an unplanned look-see?
