POBnow offers its product surveys in a searchable, user-friendly, regularly updated web format; laser rangefinder survey kicks off rollout.

In 2004,POBpublished an inaugural laser rangefinder product survey in our April issue, complete with the participating manufacturers' specs for their products' aiming/display/measurement and software and advanced measurements features, available accessories and more. We were happy to be the producer of this exclusive product survey.

This year, we've taken it yet another step further. POBis excited to announce our 2006 Laser Rangefinder Survey in asearchable, user-friendly web format. As part of our efforts to provide superior information for our readers and online visitors, we will be enhancing all of our exclusive product surveys through this multimedia format.

Our new format will better serve you, our valued readers, as well as the product manufacturers and distributors. We hope you use our new format to research products before making purchasing decisions as you have with our printed surveys. With our new, easy-to-use online format, you will be able to review the specs of a particular product or compare several products at a glance, along with the accompanying notes and product shots provided by the manufacturers. Manufacturers will regularly update their entries inPOB's surveys to keep you updated on what products have been discontinued, which products have had improvements made to them and which products are new to the market.

The Benefits of Laser Rangefinders

Used universally with GPS-based mapping systems, often in a reflectorless mode, laser rangefinders are great devices for determining the location of inaccessible points from a GPS-established position. Laser rangefinders can extend the positioning capabilities of a GPS system through electronic data transfer of the distance and related information from the rangefinder to the GPS controller. This data transfer may occur through a command sent from the "master" GPS system to first make a measurement and then send the data, or to automatically or manually follow a measurement on the rangefinder that the user initiated. Use of rangefinders in this capacity has increased the desirability for built-in slope reduction capability (tilt sensor). Electronic compasses were also added so the complete vector could be measured. While not all laser rangefinders have the slope reduction and azimuth determining capabilities, they have all improved in characteristics such as range, weight, power requirements and accuracy.

With the inclusion of the slope reduction and azimuth capabilities, depending on whether the device is handheld or mounted on a tripod, the user can make an appropriate selection to achieve the level of accuracy desired. While the accuracy of total stations is not achieved, the convenience, speed and portability of the technology makes it a sound choice, especially where it is impractical, impossible or imprudent to use a total station.

Pointing systems, which began with sighting telescopes mounted on top of the units, now also include heads-up displays (HUDs), markers in the field of view of binocular systems and visible laser dots. Software functions run the gamut from calculation of coordinates to intersections to determining azimuth and distance between two observed points. Other software routines found in this batch include various options to determine height, coordinates, vertical distances between the observer's position and the point being observed, or between two observed points; settings to prevent false measurements by eliminating the distance ranges at which clutter along the line of sight may return a spurious signal; and inversing between points. Some have internal data collection capabilities.
