I have listed all of the positives - There are two other slight downsides to using this system abd it would appear that they are only going to come into play when bowhunting - because the deer (or other game) may be very close to you when you first see them...
It takes just a second longer to bring the binos to bear when you want to use them - with a harness (which is the minimum I think you would want to use - the neck strap is for the birds) you simply raise the binos, flip off the front and rear covers and you in business - with this case it is just a little slower however
What I gave noticed is that the objective lens covers on my binos have little thumb tabs on them and in most cases just pulling thrm out of the case opens these covers - so that was a hidden bonus!
The other thing is that while the case is softly made and opens and closes almost silently, there is the tiniest bit of noise involved on getting the binos out of the case
This would be a problem ONLY if your quarry were literally right on top of you
Let me start off by saying that I am a scaredy cat.
For someone that spent 3 years in 82nd Airborne jumping out of all manner of military aircraft, my friends find this ludicrous - but... it is what it is!
Climbing stand? Yep, still scared - put me up 15' and that is about it.
Ladder stands? I am better in these - but still cautious.
Chain on stands? Used to love them, now they terrify me.
I was once ridiculed for putting chain on stands waaaay too high - some of my friends...
