On my last trip I had no problems with my carry on baggage.
In side my carryon I had the follwing:
4 spare rifle scopes in mounts.
2 pair binos.
Rangefinder.
5 Surefire Flashlights, including 2 set up to mount on a rifle scope, and the M3 Guardian, about the size of a 2 D cell flashlight.
12 Petzal headlights [most for the trackers, PH and crew].
About 40 extra batterys for above lights, along with extra bulbs.

My wife had 4 scopes in her carry on as well as binos etc.
No problems at all.

That must be more than $10K worth of stuff in your carry ons.

My last 2 elephant hunts I did not even bother to take the binos out as they were not needed at all. Next trip they will stay at home. All I really need are 3 pair of undies, 3 t-shirts, 3 pair of socks and a toothbrush. If the checked luggage arrives that is fine, and if not I will rent a gun in Harare.

That is why they were in my carryon.
Heck the bag only weighed 48 lbs.
