Key Considerations when Purchasing a Laser Boresight

Laser Color/ Quality

The laser light for bore sights are usually green or red in color. The green color laser light is usually better and a tad bit more expensive compared to the red laser light as the green laser is clearer to be viewed during the daytime or under direct sun.

However, under low light conditions, both red and green laser lights are excellent so you are able to view the laser dot on the paper very easily once sighted in. The laser quality depends on how well you can view the laser light as well as the dot when aiming at your target.

Battery Life

The battery life of your laser bore sight is very essential. Hunting trips usually take a long time, at least a whole day if you are a serious hunter. Therefore, batteries which longer shelf life are preferable so you can save cost of buying new batteries frequently and changing them each time. You will also be able to concentrate more on your target rather than worrying about your battery level each time as the laser light will most likely drain your battery.


Once you get the hang of the setup and the zeroing in process, you can easily handle your laser bow sight. You just basically have to align your bore sight according to the laser dot and set the distance between your target and the weapon. With hi-tech systems such as the Ballistic Targeting system, it will be so much easier to sight in your weapon as the targets can be printed out and adjusted accordingly to set the target distances.

You should also take into consideration the O-rings of your laser bore sight. Handle them properly by applying recommended lube and Vaseline onto it to ensure they are tightly secured to the end of the barrel.


Choosing the best laser bore sight well suited to you is no easy task. You should take into consideration factors such as battery life, durability, laser light performance and quality as well as setup. Getting yourself a hunting camera for you to document your hunts can be useful as you can learn from your mistakes. Therefore, I hope my review assists you in making the right choice.
