The best laser level kit has the features that match your particular needs. A typical laser level kit has a fully adjustable 360-degree swivel base, an adjustable tripod or mounting pole, and two laser prisms, one for a straight beam and one for a 90-degree bent beam projection which is visible up to about 30 feet (9.14 m). Most laser level kits feature a self-leveling which provides accurate level and plumb laser lines. Most of the lower priced laser levels will not project a beam which is visible outdoors in the sun.
Accuracy is also an important factor to consider when choosing the best laser level kit. Even the best laser level kit is worthless unless it has a solid base or foundation. A 360-degree swivel unit with a quick-release mount is a must-have for any laser level kit. Since accurate measurements are essential for any construction or remodeling project, a stable and secure base unit is required. Most laser levels will have a camera mount and attach easily to a standard camera tripod, and other units will include a large or small tripod or even a mounting pole. Some of the more expensive laser levels have a built-in alarm which sounds if the level is altered.
The type of beam projected and its brightness level is also an important consideration in choosing the best laser level kit. Lesser quality laser levels may utilize optics and lenses of a lower quality, which may produce an inferior beam that is harder to see, especially over a long distance. Look for a laser level kit that can project a vertical and horizontal line at the simple touch of a button. Another helpful feature to look for in a laser level kit is a detector to assist you in establishing a perfectly horizontal beam line over long distances, where a laser line is virtually invisible. The receiver unit can still see the laser level and assist in locking on and projecting the correct level beam.
A self-leveling or automatic leveling capability is a must for any effective laser level. This feature allows the laser level device to determine the accurate level line in any situation, at the push of a button without requiring you to check any bubble vials. The better laser levels will automatically adjust to the correct level line without any operator intervention. This function works best with a remote control so that the operation does not disturb the device. Remote control of all functions is a handy feature, especially when your hands are otherwise occupied in another part of the room. Other considerations when looking for a laser level kit are superior durability, ease of transport, a rechargeable battery pack and laser glasses which provide a clear view of the projected laser beam.
The best tools are the tools that are used the most, and this applies to laser levels as well. If you are going to use a laser level to put up some pictures or hang a few shelves and then leave it in the toolbox for the rest of the year, this may not be the tool for you. If you are continually remodeling, building, or installing trim then a quality laser level is likely to be a very useful tool for you.
