Bosch GLM 50 C Laser Measure Review: Still Worth Buying?

Quick verdict

The Bosch GLM 50 C is a mid-range laser distance measure that has been on the market for years, and after reading the maker's specs, the Amazon listing, three independent write-ups and two video reviews, our verdict is simple: it is still a good choice if you want a laser measure with a clear color screen, a full set of modes and an optional phone app.

It is not the newest Bosch, and it is not the toughest. But buyers keep praising its accuracy and ease of use, and reviewers describe menus that make sense. If you are new to laser measures, start with our laser distance meter basics. This page is about one exact model.

Is the GLM 50 C still sold, or has it been replaced?

We checked, because this matters. As of 13 October 2026:

• The GLM 50 C still has a live Amazon listing in the United States, with the 165-foot range and plus-or-minus 1/16 inch accuracy in its bullets.
• Bosch sells a newer-looking relative, the GLM 50-27 C, in other markets. Bosch's own page for it says it has longer battery life than the GLM 50 C, and lists IP65 protection, AA batteries, Bluetooth 4.2 and drop resistance from about 1.5 meters. The page does not say it replaces the GLM 50 C, so we will not claim that.
• We did not find the GLM 50-27 C in our Amazon US search. What came up instead was Bosch's Blaze line (for example the GLM100-23 and GLM165-22 families), which is Bosch's US range of laser measures.
• At least one retailer's page for the GLM 50 C lists it as discontinued in its region. Stock and availability differ by country and seller.

In plain words: the GLM 50 C is an older model that is still on sale in the US, and Bosch has other models above and beside it. If you can buy a GLM 50-27 C where you live and want the tougher rating and longer battery life, it is worth comparing. If you are buying in the US on Amazon, the GLM 50 C is the one you will most likely see.

What you get

According to the listing and the reviews we read:

• The laser measure with a backlit color display that rotates so the numbers stay upright.
• Two AAA batteries, a hand strap, target cards and a pouch in the box.
• Real-time length, length, area and volume, plus indirect (Pythagoras) measuring, stake-out and an inclinometer for level and angles.
• Bluetooth to the free Bosch MeasureOn app.
• A quarter-inch tripod thread, according to Tools in Action's spec list.

Hammer and Home's video walks through the modes one by one: wall area for paint or drywall, volume for concrete, stake-out for fence posts or beam spacing, and a built-in level that shows degrees when you turn the tool on its side. It then pairs the tool to an iPad to put arrows and dimensions on a photo of a couch.

What buyers and testers say

We read the customer review summary on the Amazon listing, the Tools in Action and Gadgeteer reviews, a long forum thread and two video reviews. The same points come up again and again.

The three things buyers praise most

1. Accuracy. The listing's review summary says customers find it extremely accurate. In The Tall Carpenter's video, he cuts a board to a reading and it fits tight, and a check against a Leica Disto D110 over about 12 meters differed by around a millimeter.
2. Ease of use. Buyers describe it as point, click, record, and easier than fighting a metal tape alone. Tools in Action praises the simple menus and the way the reference edge changes with a single button.
3. The screen and the small size. Customers like the bright, easy-to-read display and a body small enough for a pocket. A Festool Owners Group member who had owned the older GLM 50 called the color screen a big step up.

The most common complaints

1. The app is hit or miss. The listing summary says app opinions are mixed. Tools in Action notes that the value of Bluetooth depends on whether you actually use the app.
2. Limited memory. The Gadgeteer found only 30 stored readings without the app, with no names or times on them.
3. Technique matters. The Gadgeteer's reviewer saw some off readings and put them down to how the tool was held. A tool this fast makes it easy to rush. Rest it on a surface for tight work.
4. Battery behavior. One reader comment on the Tools in Action review reports a unit that died after short use and recovered after resting. The reviewers themselves saw no battery problems, and the editor suggested that unit was defective. We found no wider pattern, but it is worth testing yours when it arrives.

Pros and cons

How it compares

Against budget laser measures. Cheaper meters measure distance fine. What you give up is usually the clear screen, the tilt sensor and tidy modes. Buyers who use a laser a few times a year are often happy with a basic one. If you measure weekly, the extra features here save time.

Against the GLM 50-27 C. If you work on rough sites, the 50-27 C's tougher rating and longer battery life on paper are the reasons to look at it. Bosch lists the same 50-meter range and about 1.5 mm typical accuracy for both, so the measuring itself is similar.

Against Bosch's Blaze models. These are Bosch's current US laser measures, with different ranges and features. We did not compare them feature by feature here, so check the listing for each.

Against a Leica Disto. In The Tall Carpenter's video he compared the two on a 12-meter shot and saw about a millimeter of difference. For most home and trade tasks, that is not a deciding factor.

Against a tape measure. A laser is quicker for rooms and long runs, and lets one person do the job. A tape is still better for small parts, curves and lumber. Most people end up with both.

Tips if you buy one

1. Check the reference edge. If every number is off by the same amount, you probably have the wrong measuring edge selected.
2. Test it once. Compare a reading against a tape on a wall you know. It builds trust and catches setup mistakes.
3. Rest it on a surface for tight work. Pressing the button can move the tool.
4. Aim at a plain, solid wall. Glass, mirrors and shiny metal can scatter the beam.
5. Turn readings into quantities. Our square footage calculator on figuremyhome.com helps turn length and width into flooring or paint amounts.

Usefulness 8/10 · Value 7/10 · Durability 7/10. This is our own opinion, based on specs, buyer reviews and independent tests. It is not an Amazon or customer rating.

If you will mostly measure outdoors, pick up a pack of AAA batteries and keep the included target cards in the pouch.
