Your whole sight tape from two marks.
For compound bows with a single-pin slider sight. Shoot two distances, type what your sight scale reads, and PinGap works out where every yardage belongs. Print the tape at true size on a home printer, cut it out and stick it on.

You shoot two marks. PinGap fills in the rest.
Elk bow, 70 lb · 280 fps · 452 gr arrowThree reasons to choose PinGap
Buy it once and keep it. No account to create, and it works fully offline at the range or in the field.
Print a calibration page, measure its two 100 mm bars with a ruler, and PinGap corrects every tape for that printer.
Short-range marks that fold back above 20 yd are handled, and the tape shows how sure each part is: solid between your marks, fading beyond them.
The corrected mark, fast.
Type the distance from your rangefinder and read the angle from the phone's tilt. PinGap gives you the pin setting for that shot.

Enter shaft, point, insert, nock and vanes. PinGap adds up total grains and works out FOC, kinetic energy and momentum at your bow's speed. Enter a measured balance point to replace the FOC estimate.
Calculated marks are estimates. Always confirm your marks by shooting at known distances before hunting or competing.
