The Ishi Archery Pins app. Is an easy, simple and accurate way to set up your pin sights using your smart phone. Just shoot your bow at 20-yard and set your 20 yard pin, then hold the phone up to your sight and position all other pins to the desired yardage. It’s that simple!
To get started you will need to know the *speed of your arrow ft/s (feet per second), *arrow weight (grains), distance from your sight to your peep sight (inches) and finally the distance from your peep sight to your arrow (inches). Enter these numbers into the app then click the calculate button and you have a display that shows you where to set all your other pins on your smart phone.
To get these measurements go to your local Archery shop and bring a tape measure.
*Shoot your arrow throw their chronograph (speed of arrow)
*Ask them to weigh your arrow (you can also find the weights on the web from the manufacturers (arrow, knocks, inserters, points and fletching)
* Give them you tape measure and ask them to measure the distance from, sight to peep and peep to arrow when you are at full draw.
