When shooting in a cross-wind you can use the bubble level to intentionally cant the top limb into the wind to compensate for its sideways push. For example, suppose the wind feels moderate - maybe 10 to 15 mph. Your practice sessions have told you that such a wind requires that you cant the bow a half bubble into the wind. Tip the bow until the bubble is correctly positioned and then aim with the pin dead-on as you normally would. This simple step eliminates the need to guess where to hold at different ranges as the canting bow automatically takes care of this.
Many companies make sights with a bubble level built-in.
Consider one of these next time you buy a new sight. In the meantime you can try one of the after-market styles that attach to the inside of your pin guard, or to your pin slot. Hunting Tips Look for a lightweight bow. This will make it easier to carry it if you walk long distances through the woods.
