Mechanical Efficiency
PNL Testers measures how efficiently your compound bow transfers stored energy into the arrow.
We analyze:
Force–draw curves Stored energy mechanical efficiency percentage Arrow energy transfer
Deliverables:
Full PDF report with graphs, tables, and calculated metrics.
Static Spine
We provide precision static spine measurements using controlled, repeatable instrumentation.
We test:
Measured static spine (deflection) Variation between shafts Manufacturer vs. actual spine comparison
Deliverables:
Full PDF report with measurement tables.
Custom Testing & Business Services
For manufacturers, pro shops, and creators needing detailed physics-based testing.
Available tests:
Aerodynamic drag (Fd) & drag coefficient (Cd) Velocity loss & time-of-flight studies Arrow stability & rotation testing Precision/accuracy (mean radius) analysis Product validation for R&D and marketing
Deliverables:
Custom reports tailored to your project.
