Simmons 801405 Rangefinder, 4x20LRF 600

Written by Michael on . Posted in Laser Rangefinders

Zeroing on a teeny tiny flag is hard enough, making sure the ball lands where it is supposed to is a challenge that has floored better golfers than you! If you are a novice golfer or you want to preserve your eagle eyes, then the Simmons 801405 Rangefinder, 4x20LRF 600 is just what you need. This device provides golfers accurate range from 10 to 600 yards at least and it comes with a 4x magnification setting that can bring the subject you are focusing on closer. The Simmons 801405 comes in black and offers crystal clear optics that can make that far off flag seem as if it is right in front of you. How is that possible you ask? When the device is activated it gives off (safe) infrared pulses of energy that help the user determine the distance between himself (and herself) and the target with almost pinpoint accuracy. This it offers in both yards and meters which are displayed on the in-view LCD that offers clear views of the range. However, you can only get accurate range for a single yard, which will be enough for you if you are new at the sport. Range and Capabilities So far we have learned that this baby offers: Magnification up to 4x which allows golfers to zoom in with accuracy 600 yard ranging capabilities Complete accuracy up to 1 yard. However, the Simmons 801405 has a lot more going for it than just its range and magnification capabilities. It also boasts a number of adjustments and features that can aid you in bringing your A game to every game. If it is taken care of it can provide you years of service so read the manual that comes with it carefully. Infrared Rays for Accuracy The device is activated by a single button which when pressed emits the aforementioned infrared energy rays. These calculate the distance from a subject by measuring the time it takes for said rays to discharge from the rangefinder, bounce off the object and return. The maximum range those pulses can cover will depend on the reflective nature of the object you are targeting. For most it is 400 yards or 366 meters while for extra shiny objects the range is 600 yards or approximately 549 meters. In other words, be prepared to ruin a couple of shots the first couple of times you use this rangefinder; you will get shorter or longer shots than expected according to the reflective properties of the target and also the weather you are measuring in. This includes the size, surface finish and shape of the object so the brighter it is, the longer the range you will get. Take the color red for instance. That shade is as bright as it gets so a rosy flag will look way further than it actually is. Understandably, you can get accurate enough range with black, but if that dark…

Range and Capabilities

So far we have learned that this baby offers:

  • Magnification up to 4x which allows golfers to zoom in with accuracy
  • 600 yard ranging capabilities
  • Complete accuracy up to 1 yard.

However, the Simmons 801405 has a lot more going for it than just its range and magnification capabilities. It also boasts a number of adjustments and features that can aid you in bringing your A game to every game.

Infrared Rays for Accuracy

The device is activated by a single button which when pressed emits the aforementioned infrared energy rays. These calculate the distance from a subject by measuring the time it takes for said rays to discharge from the rangefinder, bounce off the object and return. The maximum range those pulses can cover will depend on the reflective nature of the object you are targeting. For most it is 400 yards or 366 meters while for extra shiny objects the range is 600 yards or approximately 549 meters.

In other words, be prepared to ruin a couple of shots the first couple of times you use this rangefinder; you will get shorter or longer shots than expected according to the reflective properties of the target and also the weather you are measuring in. This includes the size, surface finish and shape of the object so the brighter it is, the longer the range you will get.

Take the color red for instance. That shade is as bright as it gets so a rosy flag will look way further than it actually is. Understandably, you can get accurate enough range with black, but if that dark object seems teensy in the distance then you may have difficulty getting accuracy.

The angle you are measuring the range from will also affect the reading you get. So if you are focusing at a 90° angle (i.e. the surface of the target is perpendicular to the path of the energy pulses being emitted) then you can get precise readings. If you are standing on an incline on the other hand, then the angle will be too skewed to provide accurate measurements.

The lighting conditions will also have an effect on the actual measurements that you receive from the rangefinder. If you are playing during an overcast day or there are more clouds in the sky than normal, then you can the device will work at its maximum potential. Ironically, you will probably get incorrect range measurements on bright and sunny days.

Operational Summary

The Simmons 801405 looks like a small camcorder, but it won’t shoot any movies for you or that great shot you are aiming for. But it’s as simple to use as one though. While you are peering through the monocular (just a fancy word for the lens), press down on the power button to activate the device until you see the display LCD display light up at the bottom.

Aim the device at an object that is at least 10 yards away and release the power button. The rangefinder will display the range measurements for at least 30 seconds so memorize them before they do. To take more measurements, focus on other targets and press down on that button once again to get new readings. Whatever you do, do not turn around the rangefinder and try to look through the lens, especially when it is active! Like any laser, those rays will damage your eyes which last time we checked, were crucial for seeing!

Features

The Battery

The Simmons 801405 rangefinder’s LCD has illuminated indicators that give the unit of measure when the device is active and emitting lasers. It also lets the user know when the battery charge is low with the battery charge icon which will indicate if the device is fully charged, 2/3rd charged, 1/3rd charged or when it is about to run out. The icon will start blinking when this happens and is an indication that the battery needs to be replaced.

When you need to replace the battery, remove the cap that is screwed on top counterclockwise. This will lift the door of the battery allowing you take out the old ones and replace them with new ones. Even if your device does not run out of use for a year, it would be a good idea to replace the batteries with new ones every 12 months. That’s what the experts and manufacturers say anyway so it must be true!

Unit of Measure

As mentioned before the Simmons 801405 can measure in yards as well as meters and these will be indicated on the lower right part of the LCD screen. To choose between the two, turn off the device first so that it can reset to the new settings. Hold the Power button down for at least 5 seconds to get an accurate reading. As long as the button is depressed, the device will keep toggling between yards and meters so you have to be quick.

Once the unit of measure you need lights up press that button like your life depends on it. Just kidding, a long press will do. When you turn off the rangefinder, it will return to the last unit of measure it was on so you won’t have to switch each time.

Optical Design

The Simmons 801405 rangefinder has a fixed monocular optical system that allows users to view the targets they are focusing on with clarity. The liquid LCD display is in-built in the system itself and displays several features which have been discussed before. You will also see small, black spots that will appear on the optical system. These are completely normal so no need to freak out when you see them. They will not have an effect on the performance of the unit whatsoever.

Specifications

Dimensions: 4.2 x 9.6 x 1.9” so it can easily fit in a pocket.

Accuracy: plus or minus 1 yard

Magnification capabilities: 4x

Power: runs on 9 volt alkaline batteries

Eye Relief: up to 20mm

Cleaning

The unit also comes with its own case and can be cleaned free of dust when it is blown on. You can also use a soft lens brush to ensure the device does not get damaged. If you want your Simmons 801405 free of fingerprints and smudges, rub a soft, cotton cloth in a circular motion across it. Don’t use any old cloth lying around. It could make the device dirtier than it is and if the cloth material is coarse the lens can get irreparably damaged. If the lens is too grungy for the soft cloth to work, then use special photographic lens tissues and cleaning fluid (such as isopropyl alcohol) to clean.

Note: DO NOT douse the device with the cleaning solution. Apply a little on the soft cleaning cloth and then clean it.

Troubleshooting

  • If the LCD screen does not light up when you press the button, take out the batteries and place them back in. If that doesn’t work, then it probably means the batteries need to be replaced. Do not use heavy alkaline batteries though.
  • You won’t need to clear the last ranging measurements before targeting something else on the range.
  • Make sure the LCD is lit and the power button is pressed down to get readings
  • Hold the device steady when the button is pressed down
  • Make sure your finger is not blocking the lens while you are ‘ranging’.

Needless to say, the Simmons 801405 Rangefinder, 4x20LRF 600 golf ranger might be the only thing you need to refine your golfing skills and take them to the next level.
