Cooper Ray Mini Pocket Laser Measure Review

One owner worked out exactly why this is hard to read outdoors, and it has nothing to do with the laser. The display sits deep in its recess, so the bezel casts a shadow across the numbers. That is a design observation, not a complaint about brightness, and we have not seen anyone else make it.

Verdict

Well liked by the people who bought it for the right reason, on the weakest rating of any pocket unit we cover.

Owners who wanted something pocketable for rooms and furniture are pleased. At 3.8 across 124 ratings it sits below every comparable tool here, which is reason enough to check it properly in the first week.

The shadow problem, which is a design issue rather than a brightness one

One owner found it a bit difficult to read in sunlight and, unusually, explained why: the depth of the display is rather deep and prone to edge shadow.

That is a different fault from the ones we normally document. Almost every complaint about reading a laser measure outdoors is about the screen being too dim or washed out by glare. This is about geometry. If the LCD sits well below the surrounding case, the bezel throws a shadow across part of the numbers whenever the sun is off to one side.

Worth knowing because it is not fixable by a brighter backlight, and because it is the kind of thing you only notice once somebody names it. Look at how deeply recessed the screen is on any small tool you are considering.

What it is genuinely good at

The most detailed positive review describes it becoming a favourite addition to a toolbox. Compact enough for a pocket, accurate, easy to use, with measurements they describe as fast and consistent, and much more convenient than pulling out a tape for every task.

Their use cases are the ones this category is really for: measuring rooms, measuring furniture, and DIY projects around the house. They praise the display as easy to read, indoors, and note the device feels solid despite its size.

Another owner calls it very functional and quite accurate, and mentions they will make a belt case for it, which tells you one does not come in the box.

The rating, stated plainly

At 3.8 across 124 ratings this is the second lowest score anywhere in our review set, and the lowest of any pocket unit.

For comparison, the 55 ft pocket LDM holds 4.5 across 233 ratings and the CRAFTSMAN pocket laser holds 4.4. Budget units in this category normally sit between 4.1 and 4.6, so anything at 4.0 or below is unusual and worth pausing over.

We are not going to invent a reason for it. The negative reviews we can read are about signal strength and readability rather than accuracy, and none of them contain the kind of documented failure that has led us to reject other products. But a low average across a hundred plus people is information in itself, and it is the reason this page recommends checking the tool properly rather than trusting it.

How to check it in five minutes

Two tests, in this order, and they answer different questions.

Repeatability. Rest it on something solid so it cannot move, aim at a fixed point, and measure four times. Identical readings mean the tool repeats.

Accuracy. Measure something you can check with a tape, ideally at both a short and a long distance. A consistent offset can be allowed for. A changing one cannot.

The full procedure is here, and on a tool with a 3.8 average we would do it on day one rather than day thirty.

Who should buy it

Someone who specifically wants a pocket tool for room and furniture measuring, is buying somewhere with easy returns, and will test it on arrival.

Who should not

Anyone measuring outdoors, both for the 100 ft red beam and the display shadow. Anyone whose measurements end at a saw. And anyone who would rather buy the better rated pocket alternatives, which is most people.

What to buy instead, by reason

If you want a pocket unit with a better record. The 55 ft pocket LDM holds 4.5 across 233 ratings, is rechargeable, and owners praise how quickly it locks a reading.

If you want a brand name. The CRAFTSMAN CMHT77721 is smaller still at 1.5 by 2.5 inches, with the caveat that owners report about a year of life.

If you want a pocket clip rather than a case. The Klein 100 ft has one, plus 1,120 ratings and a selectable reference end.

If pocket size was not really the requirement. The RockSeed two pack gives you two units for about the same money and has the largest owner sample in the category.
