  Users who need more power and visibility may consider the powerful version of this pointer. It comes with an enhanced optical system that increases the laser beam's brightness and range. This pointer can reach several kilometers depending on atmospheric conditions.

• Adjustable Focus JD 303:

  Both beginners and expert users can adjust their pointers for the desired focus. This model comes with a lens that can be moved to expand or minimize the laser beam. When the beam is expanded, it covers a large area or region, and when it is focused, it can reach a very small point far away. Users can use this model for burning objects and engraving. It also works well for hunting and searching.

• Waterproof & JD 303 Pointer:

  Wet and muddy conditions should not stop users from pointing, highlighting, or tagging objects. This model comes in a robust and sealed housing that prevents moisture and water from damaging the internal parts. It allows users to work outdoors and in rainy or wet conditions easily.

• Presentation JD 303 Laser Pointer:

  This model has additional features like built-in timers, Ergonomic designs, and red-light pointers for users who need it for PowerPoint presentations or business meetings. Some versions come with RF (Radio Frequency) laser pens, which allow users to transmit laser beams from a distance of 10 meters or more.

Functions & Features of Laser Pointer JD 303

• Power Output:

  The JD 303 laser pointer has a power output of 1-5 milliwatts. This is the standard for confiscation-grade green lasers. Lasers in this power range are highly visible and can burn or cause permanent eye damage if pointed at anyone. This power output is sufficient for creating bright beams and dots visible even in broad daylight.

• Exact Wavelength:

  The JD 303 pointer's wavelength may vary, but common wavelengths are 532nm for green and 650nm for red. The 532nm green laser is highly visible and may appear to the naked eye to be brighter than a red laser of higher power. The 650nm red laser is less expensive but is useful for other things like indicating an object in dark areas. It is not as visible in bright daylight, though.

• Range:

  Green laser pointers can reach more than 10 miles, but objects with the naked eye cannot see the beam. The JD 303 model pointer can light up objects up to a distance of 1 mile indoors and 50 yards outdoors in daylight. The JD pointer shows its beam more clearly at night and in foggy conditions.

• Focus Adjustable Lens:

  Focusing laser pointers can change the size of the dot or line the laser makes. The dot made by the laser when it hits an object is called the point of impact. The line made when the laser is shone sideways is called a laser level line. Some laser level lines are straight, but the ones with a focusing lens can make lines that curve or bend.

• High Visibility Output:

  Sometimes, focusing laser pointers may not work well, or the laser level line may be too straight to see. At those times, a person may need a second or a third laser pointer to help them see the laser beam better. comparing the brightness of the pointer's beam can also help decide which one works better. Pointing the laser at a bright glass window also helps the laser beam show better.

• Durability and Robustness:

  The JD 303 laser pointer is robust. It can resist accidental falls and light rain but is not resistant to water. It fits well inside a person's hand, so it does not get lost. Some models have clips that fit onto pockets or notebooks.

• Beam Visibility:

  The JD 303 model offers good visibility of the beam, especially if conditions are not very bright. Factors like fog, smoke, or darkness will make the laser pointer show its beam better. The beam should be visible enough to be tracked by the eye without the pointer shaking.

Applications of laser pointer JD 303
