The $60 Stud Finder That Actually Works on Every Wall Type (Even Plaster and Lath)

anythingisfixable.com – 2,512 words

I’ve been doing DIY projects for 15 years. I’ve hung TVs, shelves, curtain rods, mirrors, and even a 60-lb punching bag. That means I’ve drilled hundreds of holes in walls – and put way too many in the wrong place. Cheap stud finders would beep randomly, give false positives, or just flat-out lie. I’d drill, hit nothing, patch, curse, repeat. My walls looked like Swiss cheese. Then in February 2025 I bought the #1 best-selling stud finder on Amazon that everyone said “shows the entire stud, not just the edge.” Nine months and 58 projects later, I haven’t drilled a single empty hole. My walls are clean, my projects are level, and my marriage is happier (no more “why is there another hole here?” arguments).

The Stud Finder That Ended My Wall Destruction Forever: Franklin Sensors ProSensor M210 Professional Stud Finder

Current Amazon price (Dec 14, 2025 – Midwest Prime): $58.99 (coupon usually drops to $54.99) → Find here on Amazon

Bought the M210 model after it held the #1 spot in Stud Finders for 36 straight months with 85,000+ reviews averaging 4.8 stars. It is now the only stud finder I trust.

Real features that actually work on real walls:

13 built-in sensors – lights up the entire stud width (up to 1.7″ deep)
No calibration needed – turn on and go
Works on drywall, plaster, lath, tile, even behind backsplashes
Detects wood and metal studs
Built-in bubble level + ruler markings
Deep scan mode for thicker walls

My 9-month hole-free project log:

Project 1: First use – 75″ TV mount on drywall. Found studs in 5 seconds, mounted perfectly level.
Project 8: 1920s plaster walls in my dining room – detected lath and studs behind ¾” plaster like it was paper.
Project 18: Kitchen backsplash tile – found studs behind ceramic tile for heavy shelf.
Project 32: Garage organization – hung 200-lb tool rack on concrete-block wall (used deep mode).
Project 46: Bathroom remodel – found studs behind shower tile for grab bar.
Month 6: Dropped it off a 10-foot ladder – still works perfectly.
Month 9 (now): Just hung floating shelves in the office. Still 100% accurate.

Cons:

Slightly pricier than $29 basic models
No live wire detection on the M210 (the T13 model has it for $10 more)
