UltraLyte Overview

Laser Technology’s UltraLyte Series were created to provide police agencies with the most durable and reliable speed enforcement tools on the market. No other laser can compare to the UltraLyte’s ruggedness and courtroom reliability, which is why our lasers are used 3 to 1 around the world.

LTI 20/20 Ultralyte 100 LR

Every UltraLyte model has a high-impact waterproof casing that has been proven time and time again it’s able to hold up in the harshest conditions.

Some have referred to the UltraLyte laser as “a tank” because they truly do stand up to all kinds of situations faced by law enforcement professionals.

All our laser speed guns have LTI’s exclusive Accuracy Validation software, which ensures the accuracy of every speed measurement before it even displays reading in the device.

Accuracy validation is what makes all LTI lasers the most dependable speed devices in the world and why they always have stood up in court.

All UltraLyte models have pinpoint targeting, which is the only effective way to enforce speeds within multilane traffic. The laser’s beam is approximately 3 feet wide when it reaches a distance of 1000 feet away. This is how our equipment makes it possible for officers to visually identify a speeding vehicle, pinpoint its exact location on the roadway, and then validate its precise speed.

Providing unmatched versatility at your fingertips and offering a wide variety of add-on options – you can collect and report speed statistics, enforce the 2-second following rule, capture an image of a violator’s license plate or even map a crash or crime scene. With a range of models, there is sure to be an UltraLyte with the features to fulfill your needs.

Lijst met codes (uit de handleiding)

Code Explanation
doF Display overflow. The measurement exceeds the display
capacity. It is possible to receive a doF message in the
scope and still have a valid measurement display on the
E01 Measurement error – target never acquired. The target
was out of range or was too close.
E02 Measurement error – insufficient data. The instrument’s
view was obstructed or the target moved out of range.
Measurement error – unstable targeting. Caused by poor
aiming or by panning off the target.

Measurement error – low level of interference from a light
source such as a headlight or a laser jamming device

E07 Jam detect – high level of interference from a light source
such as a headlight or laser jamming device.
E52 Temperature too cold. Stop operation.
E53 Temperature too hot. Stop operation.
Calibration or memory checksum failure.
If the error persists, contact Laser Technology, Inc.
