Hi all,

Any material softens with increasing temperature. So theoretically, the limbs of a bow get weaker at warmer climate, and arrow's velocity drops.

Can anyone tell the magnitude of this issue? What is the difference between winter and summer?Between the morning chill and noon? Or even the effect of leaving the bow in direct sun light?

I would think heat will have more of an affect on your cables/strings than the limbs. I don't think we could survive shooting in temps that the limbs could withstand LOL...

I left my Hoyt Protec locked up in under the toneau cover of my truck for 2 weeks in July here in PA. I took it out, went to the 3d range, and it shot fine. I don't shoot 3d enough to get in depth about that, maybe someone who shoots a ton in hot weather can tell ya more. I personally hate shooting in hot weather.

As far as cold goes, I sight in with broadheads in late august, and shoot regularly throughout the season to keep a eye on things. After 20 years of doing it that way, I never experienced any noticable changes in sights, only when I had a junky set of strings/cables on the bow. I've been using aftermarket strings for 6 or 7 years now, and maybe, maybe once or twice since then, I've had to move pins during hunting season, then proceeded to hunt and take game. I hunt in any weather I get time to hunt it, and the worst thing I've had happen becasue of weather is getting factory Hoyt strings soaked in a rainstorm on an '04 Xtec and then having to re-sight and re-set cam timing the next day.3 days later the strings were thrown away, and aftermarkets installed. Problem solved.

Don't worry about the limbs. Keep an eye on the strings.
