The "classic" Zen-Ray ED3 8×43 lives next to me on the passenger seat under a newspaper (though somewhat luxuriously on a full leather seat), and has been there permanently for a good ~6 years now - it has had several high speed adventures into the passenger footwell during emergency stops - all good.
It has no objective covers and I don't bother putting the eyepiece covers on (unless I am caught out in a rain shower). Somewhat of a "beater bin", even though it is my only bino. Outside temperatures range from -3°C to 47°C plus solar radiation on a black car, so gawd only knows what temperature swings it goes through inside the car.
May I suggest that if you think performance has dropped off since new originally - to blow the dust etc off the objectives and eyepieces and give them all a good 'gentle' clean with lens solution and some appropriate scratch and lint free cloth/paper ..... that's all mine ever get to bring them back - good as gold ! :t:
I suppose now that the Zen's are "classics" I may have to dig out the bin bag and give them more security and padding in the glovebox to save all the high speed impacts - that's certainly how I would treat better bins ......:cat:
Chosun :gh:
Why not just leave them in the footwell, with a long strap attached so you can fish them out quickly?
I do remember an anecdote from Bill Cook, how a binocular fell off the bridge of the ship he was on, bounced down two decks and was entirely unharmed, while a similar one was knocked silly falling over on the mess table.
This glass serves you well, you should treat it correspondingly.
