Licensed General Contractor & Independent Tool Reviewer
Nashville, Tennessee, 22+ Years Field Experience
Dane Spruill spent 22 years managing residential and light commercial builds across the Mid-South before turning his full attention to testing the tools he relied on daily. He has personally evaluated more than 160 laser levels, and precision layout instruments under real job site conditions. His reviews are grounded in the same accountability that governs a licensed contractor: if a measurement is off, the wall doesn't plumb out, and someone pays for it.

Areas of expertise
Stud Finders
Magnetic, edge-finding, AC-detection and deep-scan radar models. Performance evaluated across five wall types: standard drywall, double-layer, plaster and lath, tile over cement board, and older wood-frame construction.
General Contracting
22 years managing ground-up builds, additions, and whole-home renovations from 1,800 to 4,500 sq ft across Davidson, Williamson, and Rutherford counties. Multi-trade coordination from framing to finish.
Tool Benchmarking
Structured protocol: accuracy at 3, 10, 25, and 50 feet against a calibrated reference; battery endurance to depletion; IP resistance under active site conditions. Manufacturer specs compared against field results.
DIY Translation
A decade of explaining technical decisions to homeowners who didn't grow up in the trades. Dane knows which features matter to a weekend renovator and which are pro-spec overkill that adds cost without adding real-world value.
Layout Precision
Floor leveling, wall layout, tile installation, staircase stringers, suspended ceiling grids. Accuracy requirements by application: from ±1/16 inch per 10 feet for tile to ±1/4 inch per 100 feet for exterior grading.
"I've bought tools that cost me more in frustration and rework than they ever saved me in price. What I do now is simple: I test them the way I would have used them on a real job, write down what actually happened, and tell you whether I'd buy it again, and whether I'd recommend it to a first-timer or only to someone who already knows what they're doing."Dane Spruill, Licensed General Contractor, Nashville TN

2022 – Present
Independent Tool Consultant & Reviewer
RayXact.com, Nashville, TN
Systematic field testing of laser levels and precision layout instruments began in 2022, following a series of equipment failures across active job sites, culminating in a $2,200 tile reset on a Brentwood renovation in fall 2021 that made the problem impossible to ignore. Over 160 tools evaluated using a structured, reproducible protocol before RayXact.com published its first review. The site launched publicly in May 2026.
