Bosch DLR165 Digital Laser Rangefinder Review

Many things we review here at The Gadgeteer are devices somewhere between tech-toy and tech-gadget or accessories meant to protect, carry or power those devices. All perfectly well and good, mind you….most of those (still) make my tech-geek heart a flutter. But, other than iPod speakers or noise isolation earbuds, few assist me in my other passion; fixing up old houses, home improvement projects, working on the yard, etc.  The Bosch DLR165 digital laser rangefinder is a great gadget-tool, designed to replace your old tape measure in a multitude of construction applications.

My initial impression of the DLR165 was that it was a slick/high-tech tape measure. Allowing you to measure distance quickly and easily without the hassle of stretching a tape across a room or whatever distance you are looking at. But after playing with it I come to find out, it can do a great deal more. Once you figure out how to use some of its more complicated capabilities, it can take care of the burdensome/heavy-lift calculations that are potentially needed during construction efforts; standard length (A to B), area (A x B), volume (A x B x C), continuous length (adjusts while moving), and indirect length (Pythagorean theorem (a2 + b2= c2)) plus being able to add or subtract measurements as you go (M+ or M-, just like a calculator).

Measuring Modes:


  • Length
  • Area
  • Volume
  • Continuous
  • Indirect Length

The DLR165K, where the ‘K’ stands for kit; includes instructions, batteries, belt case, strap/handle, and the the range finder itself.

Features

  • Precision Laser Measuring Technology – Laser beam does both pointing and measuring
  • Pocket-Sized Only 4″ tall
  • Four Measuring Reference Points – Back, front, swingout extension pin for measuring from inside corners or channels, or center of optional tripod
  • Three Measurement Systems — Feet and inches, decimal feet, and metric
  • Length, Area and Volume Measuring Capability
  • Continuous Measurement Mode — Measurement automatically adjusts when walking-off distances
  • Continuous Laser Mode — Reduces the number of key strokes when making rapid sequence of measurements
  • Indirect Length Measurement Mode — Calculates inaccessible distances that cannot be measured directly due to obstruction or lack of reflecting surface using Pythagorean theorem (a2 + b2= c2)
  • Limited 3-Year Warranty
  • Ergonomic Soft-Grip Area — For sure grip and comfort

Specifications

  • Accuracy: +/- 1/16″ (1.5 mm)
  • Battery Life: Approximately 30,000 Individual Measurements
  • Dimensions: 4″ x 2-15/16″ x 1-1/4″ (100 mm x 68 mm x 32 mm)
  • Laser Class: 2
  • Laser Diode: 635 nm, < 1mW
  • Measuring Time, Max: 4 sec.
  • Measuring Time, Typ: < 0.5 sec
  • Power: 4 AAA Batteries
  • Range: 2″ – 165′

On the front of the DLR165 are the laser and distance sensor. The rear has a swing out extension pin for measuring from inside corners or channels. The rangefinder has four measuring points of reference; front, center, rear, and end of the extension pin. The device can measure between two inches and 165 feet with an accuracy of 1/16″. The measurement appears on the display almost instantaneously. Distances can be displayed in three systems of measurements; feet and inches, decimal feet, and metric.

The device has an ergonomic form and is lightweight, much lighter than a quality tape measure. Bosch includes a very simple but functional belt holder for the measuring device. Allowing the rangefinder to be at your side whenever you need it, much easier to get on/off your belt than the typical clip of your tape measure.

I have found the DLR165 laser rangefinder very accurate (using a standard tape measure as my reference). As you can see, both are measuring exactly 5 feet. I compared the two in several scenarios, all of which showed within 1/8″. That difference can easily be attributed to human error (especially over longer distances).

The DLR165 rangefinder is ideal for measuring distance with some sort of backstop (aka a wall or side of a hill or building). It would be difficult to measure a board for cutting or plotting out an area of land to put a foundation.

Unless you have someone to hold something at the desired point of measure for the laser to hit. That limitation not withstanding, this compact, lightweight, highly accurate rangefinder will be a great benefit to many future construction projects.

  1. Gadgeteer Comment Policy - Please read before commenting
  2. I have an earlier model of this and it works very well and is highly accurate. Makes measuring rooms, etc. a breeze.

  3. I am thinking of getting this for my dad for Fathers Day. What is the difference between the Digital Distance Measurer Kit and the Digital Laser Range Finder Kit?

    My dad is a pretty skilled at-home handy man, fixing things from bathrooms to molding to shelving to gardening beds to plumbing to…you name it. I’m willing to spend a little more to get the better tool but don’t know enough about either to make an informed decision. I’ve read reviews but I don’t understand the difference or why someone would choose the cheaper model over the laser range finder other than the metric/inches issue.

    Can you help please?

  4. Replacing my tape measure was one of the best decisions i have ever made! No more awkward situations fumbling around with tape. I use my bosch not only in construction projects though…it also comes in very handy whenever i build new furniture to fit a room perfectly!
