SightMark Bow Kit

SightMark Bow Kit is an offline-first sight-tape and arrow-matching studio for backyard compound shooters, 4-H archery families, bowhunter prep students, and club coaches. Build trustworthy marks and arrow setups before you reach the range so every end is spent shooting—not guessing yardage or spine.

LIVE SIGHT-TAPE WORKBENCH
Set peep height, sight radius, and anchor geometry, add a speed estimate, and choose your distances. The workbench converts that geometry into sequential yardage marks on a scaled tape preview you can trust at the line.

ARROW FOC BALANCER
Enter point, insert, shaft, nock, and fletch mass. Get a clear front-of-center percentage with a simple stability cue so builds stay predictable from practice to hunt prep.

SPINE MATCH GUIDE
Link draw weight, draw length, point weight, and shaft spine charts. Seeded aluminum and carbon families help you compare options quickly without leaving the bench.

BOW & ARROW LIBRARIES
Save compound and recurve profiles—ATA, brace, peep height, sight radius, IBO or chrono speed—with rich starter presets. Store shaft spine, GPI, length, point grains, vanes, and nock mass for fast swap comparisons across projects.

DISTANCE SETS & BALLISTICS EDUCATION
Compose practice blocks such as 20–60 yd ladders that feed the tape generator directly. Estimate kinetic energy and momentum from speed and arrow mass for ethical hunting-distance education overlays. This is a setup studio, not a score scrapbook or gear diary.

EXPORT & OFFLINE WORKFLOW
Render a high-contrast printable sight tape image to device storage or the share sheet. Toggle yards/meters and grains/grams with instant recalculation across open projects. Everything runs locally so club nights and range days still work without signal.

SEEDED DEMO KITS
Open youth recurve, indoor 18 m compound, or outdoor 3D compound demos and see a full working bench on cold start.

Spend range time shooting. Build tapes and arrow matches with SightMark Bow Kit first.
