Arixel runs a strain-engine calculation across your complete tackle chain every time you adjust drag, swap line, or tie a new leader knot. The app measures true working load — not theoretical breaking strength — by factoring in knot efficiency degradation, line age condition, rod angle under load, and friction loss through rod guides.
When you set up a rig in Arixel, the pull-test simulator shows you exactly where the chain will fail. If your leader knot drops efficiency to twenty-four percent while your main knot holds ninety-seven percent, the simulator displays the exact load threshold where the leader knot pops. You see the weak link before you hook a fish.
Six precision benches solve specific tackle problems: drag setter calibrates your reel to known force, spool bench calculates backing capacity from arbor geometry, leader match pairs diameter to main line or picks shock leader for target species, rod window checks power class against rig load, retrieve bench converts gear ratio to lure speed across six retrieve windows, and terminal bench cross-references hook strength to line rating.
