Do Rangefinders Work In Rain

The rainy season often is the period you may cancel all your hunting or golfing expeditions, sit back and kick your feet up in front of the fireplace while perusing through your favorite book.

The main reason for this is because most of the equipment you will require for these activities are not water-resistant, and so being indoors is the only alternative.

Heavy rainfall can be very destructive to devices like rangefinders that require proper care to serve you for a long time.

Unfortunately, most rangefinders you may find around are not properly suited to be used under the rain.

To fully understand how the rain prevents rangefinders from getting clear, accurate measurements, we first must understand how these rangefinders work in normal weather conditions.

How Do Rangefinders Work?

All laser rangefinders available on the market work under the same general principle, so understanding how one works gives you a general idea of how all other laser rangefinders work.

  • When you push the button to measure a particular distance, the rangefinder emits powerful laser beams in the direction of the target.
  • The beams bounce off the target and return to the rangefinder.
  • The rangefinder possesses a high-speed clock that records the time spent from when the beam left the rangefinder to when it returned.
  • With the value for time recorded and the speed of the beam known (same as the speed of light), it is easier to calculate the distance of the target from your position.

Although most laser rangefinders work with this general principle, there are a few recent models with modern innovative changes in the implementation of the rangefinder.

Effect Of Rain On The Rangefinder

As a rule of thumb, severe environmental or weather conditions can hinder the movement of the beam, or disperses the beam immediately it leaves the rangefinder.

In a vacuum, the speed at which light travels is constant, but when it is made to travel in presence of fog or rain, the speed changes.

The value of the speed of the beam also depends on the state of matter obstructing the beam.

For example, the beam would be faster in light fog than in heavy rain. Although both negatively affect the accuracy of the laser rangefinder.

The effect of rain on rangefinders is so evident that more expensive rangefinders now come equipped with a rain mode.

Which may not solve all the problems outrightly, but help a great deal. Depending on the severity of the downpour, the rangefinder could become useless.

What Can Be Done?

As we have stated, rangefinders with rain mode will still not serve you well in the case of severe rainfall.

The most common solution to tackling the problems faced by rangefinders in the rain is waterproofing.

By waterproofing your rangefinder you reduce the effect the rain will have on the device. Waterproofing stops water from getting into your rangefinder and damaging it.

Even though this may not have any significant impact on the accuracy of the rangefinder in measurement.
