Instant Pass/PRO Indicator: Quickly see if a card is dead-centered. If variances are detected, the exact deviation is locked behind the Pro tier. Universal Compatibility: Works seamlessly across the hobby’s top platforms, including eBay, COMC, Fanatics Collect, MySlabs, BuySportsCards, and virtually any website with a card image. 🔥 UPGRADE TO GEMSCOUT PRO 🔥 Need to know the exact centering split, save screen shots of potential cards, or do a little deeper surface scan of the card image; GemScout Pro will let you do all of that! ✅ Precision Centering Calculator: Unlock the exact math. Get instant L/R and T/B centering percentage ratios to know exactly what grade the card qualifies for before you buy. ✅ Multi-Grader Standards: Switch standards with one click to match your target grading company: PSA Mode: 60/40 Standard SGC / BGS Mode: 55/45 Standard Pristine Mode: 50/50 Strict Logic (TAG / BGS Black Label) ✅ Independent Split-Rotation: Is the seller's photo crooked? No problem. Micro-adjust the rotation of the underlying image AND the grading grid completely independent of one another by precise 0.10° increments to perfectly align with the card/card image borders. ✅ Smart Screenshots: Save your graded* cards with auto-generated filenames (e.g., "eBay_Jordan_RC_PSA10.png") for effortless inventory tracking and submission prep. ✅ Surface Defect Hunter (‘X-Ray Mode’): Go beyond centering. Use our filter to invert and isolate surface textures, revealing hidden creases, edge wear, and print lines the naked eye might miss. 🛠️ BUILT FOR EFFICIENCY Sports & TCG Support: Dedicated aspect ratio logic for both standard Sports cards and TCG (Pokémon, Magic: The Gathering). Dark & High-Vis Modes: Switch overlay themes to ensure the grid is visible against any dark or light card border. Pixel-Perfect Control: Fine-tune the overlay using keyboard arrow keys for maximum precision (Hold Shift for fast-nudge). 👋 FROM A COLLECTOR, FOR COLLECTORS I built GemScout because I was tired of the struggle. As a collector returning to the hobby and diving into reselling, I lacked confidence buying raw cards online. I wanted a tool that felt like holding a physical centering overlay in my hand—but for the digital world. GemScout is that tool. It stops the guessing game. 💰 PRICING GemScout uses a Freemium model. Use the basic visual overlay for free, forever. Ready for exact percentages and smart exports?
