Best Stud Finder for Hanging TV: Franklin ProSensor 710+ Review (2026)

Your new TV is still in the box, the wall mount is on the table, and one question stands between you and a Saturday afternoon well spent: where exactly is the stud? Drill into plain drywall and a heavy TV can rip straight out of the wall. Drill into a stud and it will hang there for years. The best stud finder for hanging TV is not the cheapest gadget in the drawer, and it is not the one with the most beeps. It is the one that shows you the full width of the stud, clearly, on the first pass, without a calibration dance. In this guide we review one tool that earns that job — the Franklin Sensors ProSensor 710+ — and we are honest about where it struggles too.

Quick Verdict

Best for most TV mounting jobs: the Franklin Sensors ProSensor 710+. Instead of a single sensor that guesses at an edge, it uses 13 sensors side by side to light up the full width of the stud at once, so you can see both edges and the center in one sweep. There is no calibration step, it works even if you start the scan right on top of a stud, and it finds wood and metal studs up to 1.5 inches deep. Skip it if your walls are thick plaster or double-layer drywall; depth is capped at about 1.5 inches, and no handheld finder in this price range is magic on those walls. For standard single-layer drywall — which is what most American living rooms have — this is the finder to buy first. Check the current price of the Franklin ProSensor 710+ on Amazon — prices change, so treat any range you see as approximate only.

Detailed Review: Franklin Sensors ProSensor 710+

The first thing you notice when you use the 710+ is what it does not ask you to do. Most electronic stud finders want a calibration ritual: hold it flat on an empty patch of wall, press a button, wait, then sweep slowly and hope you did not calibrate over a stud by accident. The 710+ has no calibration step at all. You press the button, place it on the wall, and slide. The row of LEDs lights up wherever a stud sits underneath, and as you move back and forth the lit section tracks the stud, so the center becomes obvious instead of a guess between two pencil marks.

That wide view is the real advantage for TV mounting. A TV bracket needs at least two solid lag-bolt points, and ideally both land in the middle of two separate studs. With a single-sensor finder you find one edge, mark it, find the other edge, mark it, then split the difference — and every step adds error. With the 710+ you see the whole stud width in one glance, which makes it far easier to center a bolt and avoid splitting the edge of the stud, the classic mistake that leaves a mount feeling wobbly even though it technically hit wood.

The 1.5-inch depth rating covers standard drywall over wood or metal studs, which is the normal case in most homes built in the last fifty years. It also matters that the tool is made in the USA and built around a simple idea — more sensors, less guessing — rather than a screen full of modes most people never use. There is no app, no firmware, and nothing to update. That simplicity is a feature, not a gap, for a tool you may use four times a year.

Pros

• 13 sensors show the full width of the stud at once — center finding is visual, not estimated.
• No calibration, and it works even when you start scanning directly over a stud.
• Finds both wood and metal studs up to 1.5 inches deep.
• Simple one-button operation; no modes to learn or mis-set before a big mount.
• Made in the USA with a straightforward, durable design.

Cons

• Depth limit of about 1.5 inches — thick plaster, tile over backer board, or double-layer drywall can beat it.
• No deep-scan or dedicated live-wire display mode like some pricier multi-scanners offer.
• It is wider than a pocket magnetic finder, so it is less convenient as a toss-in-the-pocket tool.
• Like every electronic finder, it can be fooled by dense knots, heavy texture, or metal plates — always confirm with a small pilot hole.

Who Should Buy It

Buy the 710+ if you are mounting a TV, floating shelves, a heavy mirror, or kitchen cabinets on standard drywall and you want the mounting points right the first time. It is also a good pick if you have been burned by a cheap finder before — the no-calibration design removes the most common reason cheap finders lie. Skip it, or pair it with a deep-scan model, if your home has lath-and-plaster walls or you regularly work through tile and backer board. And if you only ever hang light picture frames, a simple magnetic finder will do and costs less — the 710+ earns its keep on heavy jobs.

Tips for Mounting a TV With a Stud Finder

• Sweep slowly and twice. Go left to right, then right to left. A stud that lights up the same way both directions is a real stud.
• Find two studs, not one. Studs usually sit 16 inches apart. Once you find one, measure 16 inches over and confirm the next.
• Mark the center, then pilot-drill. A small pilot hole confirms wood (not a pipe or wire plate) before you drive a lag bolt.
• Check for outlets and switches. Studs sit beside electrical boxes, and wires run vertically from them — avoid drilling straight above or below a box.
• Use the right hardware. A TV mount needs lag bolts into studs, not drywall anchors alone, for any TV over about 30 pounds. Check current price and hardware guidance on the listing before you buy.

Frequently Asked Questions

What is the best stud finder for hanging a TV?

For most homes with standard drywall, a multi-sensor finder like the Franklin ProSensor 710+ is the best choice because it shows the full width of the stud, so you can center your lag bolts instead of estimating edges. Magnetic finders are cheaper but only find screws, not the stud itself.

Do I really need a stud finder to mount a TV?

Yes, for any TV heavier than a small monitor. Drywall alone cannot reliably hold a TV mount under load and movement; lag bolts driven into the center of studs carry the weight safely for years.

How deep can the Franklin ProSensor 710+ detect studs?

Up to about 1.5 inches, which covers standard single-layer drywall over wood or metal studs. It is not the right tool for thick plaster or double-layer walls.

Does the 710+ need calibration?

No. There is no calibration procedure — press the button and sweep. It even works if you start the scan directly over a stud, which is where many single-sensor finders fail.

Can it find metal studs?

Yes, it detects both wood and metal studs. For metal studs, use fine-thread screws rated for metal framing rather than wood lag bolts, and confirm the stud type with a pilot hole first.

Why does my old stud finder give false readings?

Most false readings come from bad calibration, scanning too fast, or dense material in the wall. Sweep slowly, scan in both directions, and confirm any reading with a small pilot hole before mounting.

Conclusion

Hanging a TV is a one-afternoon job that lives on your wall for years, and the difference between a mount that feels rock-solid and one that slowly loosens is usually a few inches of stud position. The Franklin ProSensor 710+ removes the guessing from that step: thirteen sensors, a clear full-width display, and no calibration to get wrong. It is not a deep-scan tool for plaster mansions, and it will not replace common sense about wires and pipes — but for the standard drywall living room, it is the most honest stud finder we have used in this price range. Check the current price of the Franklin ProSensor 710+ on Amazon before your next mount, and hang it once, hang it right.
