The 13-sensor ProSensor M210 is the model the Franklin faithful point to most often. Across r/handyman it's described as "much better than your typical hardware store junk stud finder," and homedepot verified-purchase reviewers say it never missed a stud where generic tools misallocated them. A woodtalkonline poster summed up the recurring sentiment: "accurate and repeatable and easier to use than others I tried... expensive, but I don't regret the cost."
The extra LEDs over the 9-sensor models give finer resolution of the stud outline, which trim carpenters and pros value. The disagreement is real, though: one high-trust r/Tools thread reports the unit "was giving me bad" reads, so it isn't infallible. At around $60 it costs more than the M150 for largely the same core capability, which is why we rank it a hair lower despite its bigger review base. For buyers who want Franklin's flagship everyday scanner and the densest LED readout, it's the standout.

I wasn't impressed with stud buddy. It only detects metal nails or other metal, so you don't know exactly what it is.
