Source: 4iiii.com (verified 2026-07-13) · corroborated by shop.4iiii.com. The official 4iiii product page (4iiii.com/precision-3-plus/) confirms this is the single-sided PRECISION 3+ "Non-Drive Side" model — shown side by side with, and distinct from, the dual-sided PRECISION 3+ PRO (29 g, up to 550 hrs) — and its Key Specifications table lists +/-1% accuracy, CR2032 Coin Cell, up to 800 hrs battery life, IPx7 waterproof rating, 9 g weight, ANT+ & Bluetooth Smart, and a 3 year warranty; Left/Right Balance is shown as a dash for this model while the Cycling Metrics row (pedal smoothness, torque effectiveness) is present. The 4iiii US shop Factory Install page (shop.4iiii.com) corroborates the identical PRECISION 3+ single-column spec table (Non-Drive Side, +/-1%, CR2032, 800 hrs, IPx7, 9 g) and describes it as a "crank-based power meter," and lists the price of $339.99 USD for the power meter installed on a customer-supplied crank. Both retailer pages price the sibling PRO separately, confirming this entry is the base single-sided sensor and not the dual variant.
