What Rangefinder Shows Red Squares Over Multiple Ranges? – Everything You Need to Know

People often ask, what rangefinder shows red squares over multiple ranges?

Let’s find out!

What Rangefinder Shows Red Squares Over Multiple Ranges?

The laser rangefinder shows red squares over multiple ranges.

The laser rangefinder is a device that uses the Doppler effect to measure the distances and speeds of moving objects. It works by sending out a beam of light, which bounces off an object and returns to the device.

The time it takes for the beam to return depends on how far away the object is from the device. By measuring this time, the distance can be calculated.

Laser Rangefinder – Eliminator Laserscope

The Eliminator Lasercopes is the most innovative and effective laser scope in the world. With just one touch of a button, they instantly calculate and display the distance to the target, including the angle.

They also instantly calculate and display the exact aim points and wind data all within the scope for complete situational analysis. No need for any additional devices or apps.

The Eliminator significantly improves your effectiveness as a huntress and the distance at which an ethical game may be taken.

The built-in range finder can now measure distances out to two thousand meters. The trajectory compensator works accurately at any magnification level, and the included inclinometer allows shooting uphill or downhill angles.

The Eliminator IV & V offers improved ballistics for centerfire, rimfire, muzzleloader, and slug guns. It also includes a wireless trigger control for laser firing.

Built-in Inclinometer

Shooting up, or down, steep hills can seriously throw off your aim point. The Eliminator accounts for that.

Eliminate Guesswork

At which range do you need to hold over to ensure a kill? The Eliminator calculates exactly where you need to hold over for your specific cartridge so you get an accurate hit every time.

Wind Information

If you want to adjust your shot for the breeze, use the Eliminator to figure out where the breeze is coming from and then adjust your position accordingly.

Heads Up Information

With the X96 reticle, you get plenty of through-the-scope info to ensure the perfect hit. This shows a target at 500 yards, with a wind value set to 0.9 holdoffs, and the hold point has been adjusted so that it’s right where you want it.

How Does the Ultrasonic Range Finder Works?

An ultrasonic rangefinder sensor allows a robot to sense objects in its path by emitting a high-pitched 40kHz tone which reflects off an obstacle and then returns to the sensor.

Using the amount of time it took for the reflected signal to reach the sensor, the distance between the robot and the obstacle can be calculated.

The usable range of a Range Finder is between 3 inches (7.6 cm) and 115 inches (300 cm). When the device tries to measure an item smaller than 3 inches, the echo returns so fast that the device cannot pick up the signal.

At greater distances, the intensity of the echo becomes too low to be detected by the device.

If the object which is being sensed has no hard surfaces, then the sound wave may be reflected at the sensor and cause inaccurate readings.

If the object being measured is spherical like a ball or has an irregular shape like a sphere, the ultrasonic sensor returns a value that is relatively close to its actual size.

However, if the object being measured is flat and hard, like a tabletop, then the ultrasonic sensor will return a value that is closer to its true size than if the object were round or soft.

To get started, you need to pair the ultrasonic range finder with a computer language such as the VexCode V5 or VexCode Pro V5.

You can then write a user program for the brain to use the sensor to control the bot. The rangefinder measures distances in either inches or millimeters.

Common Uses of an Ultrasonic Rangefinder

An ultrasonic rangefinder is a type of distance-measuring device that uses sound waves instead of light waves to measure distances. It works by sending out high-frequency sounds (ultrasounds) at different angles from the device.

When these sounds hit objects they bounce back to the device where their time of return is measured. By comparing the times of return for each angle, the device calculates the distance between itself and the object.

Obstacle Avoidance

Robots can detect obstacles by using sensors to measure their distance from them.

Many vehicles use ultrasonic rangefinders to help them avoid obstacles in their path and warn drivers when they’re too close.

Gesture control

An interesting class project is to orientate the ultrasonic range finder so a person’s arm can be moved within a given distance range of the detector. When the robotic system detects this movement it can alter its behavior.

For example, this could be utilized as an occasion where the robotic system won’t move until a person waves his/her arm over the detector. Most gaming systems have particular guidelines forbidding this sort of human interaction with the robotic system during the autonomous period of a game.


A proportional feedback control system uses the error (the difference) between the target and actual distances to adjust the percentage of power sent to the drive train.

This causes the robot’s velocity to decrease as it approaches its destination point. When it has reached the specified distance, the robot will stop moving. This helps prevent the robot from overshooting when traveling at high speeds.
