Select arrows archery

Every arrow catalog asks the same question first: what spine do you shoot? Most people answer with a guess, a forum thread, or whatever the shop had two seasons ago. Select arrows archery turns the guess into arithmetic. Enter your bow — recurve, compound or longbow — with its peak weight, draw length and brace height. Enter the arrow length you cut and the point you plan to use. The app converts all of it into an equivalent draw weight, runs the matching law, and hands you a spine group with the requirement spelled out underneath: not just "500", but "550 required, leans stiff". A cursor shows exactly where your number sits between the neighbouring groups, and a three-beam diagram draws the static deflection test the number comes from. Weight is the second half of the story. Build an arrow from components — shaft gpi, point, insert, vanes, nock — and watch total weight, GPP and FOC update together. A diagram marks the balance point against the conventional 7–15 % band, and a warning appears the moment your build drops under the 5 grains-per-pound line compounds care about. Then the part nobody shows you in the shop: the force-draw curve. Select arrows archery integrates it — let-off valley included — to get stored energy, then splits it into speed, kinetic energy and momentum for any arrow weight. Slide from 300 to 500 grains and watch the trade plainly: speed falls, kinetic energy barely moves, momentum climbs. That is the entire physics case for heavy arrows, on one screen. Everything you tune is saved as builds in a local quiver — spine, weight, FOC, notes — ready to show the pro shop. No account, no network, no analytics; every number is computed on this device. Selection charts agree within one group, and so does this app. The bare shaft test remains the final word — Select arrows archery just tells you which boxes to buy for it.
