Did you mean 4000ft or 400ft ??????? If it was 4k and now hes at sea level on Whidbey, could be noticeable difference.

I think if anything it would be the other way around. He would shoot low here.
Exactly............

I have hunted up to 10k feet and never noticed a difference, even when I sighted in at 800 feet above sea level.

Prolly had his bow upside down....shooting 400-500 yards aswell :chuckle:
Jokes aside no it's not the altitudes fault,altitude does affect everything but it's gona be a incredibly small amount in typical archery ranges

It wouldn't be a huge difference but depending on arrow and the accuracy of the individual that could make a difference. More fletching the bigger the difference in the heavier air. Becomes more noticeable the further your shoot.
If it is more than a slight difference at say 30 yards then it's most likely mechanical. Most common causes are peep slippage and string or cable creep. With BCY 8125 on a single cam bow I've seen string creep effect 30 yards by as much as four inches in a single day. That rarely ever happens with 452X. There are usually witness marks on the string if the peep has slipped.
On a hybrid cam there is much more tension on the power cable than there is on the control cable. So one usually creeps faster than the other. This pulls the cam out of timing rather easy. However, that usually advances the upper cam making it shoot lower rather than higher.
I would shoot 20, 40, 60 & 80 yards without making a change. If you only see a difference at the longer ranges it's likely the difference in altitude. If it presents at all distances it's mechanical. If it's a single cam bow I would put a couple twists in the control side of the string and see if that corrects it. If not slide the peep to reset 30 yards and everything should fall back in line.

It's a bowtech that about sums it up.
Less likely to see string creep effect a binary cam. So more likely a Hoyt or Mathews single cam. ;)
However, the faster the bow shoots the more you will notice a change in air density resistance. So if altitude is the issue it could be a Bowtech :chuckle:
Or a Bear, or a PSE, or a ...

And I like helping them out...well...because you're a Hoyt guy :chuckle: :chuckle: :chuckle:
Although I have a feeling you might be a Mathews guy by this time next year. Only six more days and you should be able to shoot the new one! Probably the most anticipated new Mathews release ever! Even I'm getting excited for this one!!

If it's a Bowtech produced prior to the Admiral or it's one of the aluminum inserted 10# club limbs it could be a failing limb issue. I'm a Bowtech fan, but I refuse to shoot those limbs. Anyone who has ever produced that limb design, regardless of manufacture, has had some sort of issue sooner or later. I used to have a strict policy, "No Mathews and No Bowtech...Ever!" Mainly due to that limb design. But everything changed around the time Savage started producing the Admiral and Mathews started producing the better limbed McPherson.
The new string materials while being brilliant in color and quite creep resistant also have a shortcoming. And that is they are extremely slick and non porous. So glues don't stick well to them and serving doesn't always stay where it is suppose to. As a result of this issue peeps slip easier and center servings don't often allow much twisting of tied on nock sets or D-Loop to change nock height. I now tie in peeps with much more serving thread and in a different pattern than I use to only a few years ago. Plus I am much more aware of how I apply pressure to my D-Loop. Making sure I always pull straight back instead of up as I draw in an attempt to eliminate any nock height slippage.
Seeing as it is a Bowtech and you are now shooting high at a lower elevation I'd say the logical cause is a slipped peep sight. Sight in at 30 yards using nothing more than moving the peep. Once completed go back to 80 and see if your marks are still good. If they are further secure your peep servings with some waxed dental floss or more serving thread. And then mark the distance from your D-Loop to the peep aperture center somewhere on the bow. So if it changes again a quick measurement will tell you if the peep is again the problem. If it measures the same you know you have some bigger problems. All archers should do this!!!

Good luck, I hope you get it worked out quickly.

What string material are you using?
