Water Resistant for Broader Applications

Now you can take your Astro Aimer anywhere, including the dewiest of star parties. It's perfect for camping, hiking and rafting. Use it in the rain, or for any emergency situation in almost any environment. Astro Aimer's green laser is perfect for pinpointing star locations as well as any other pointing needs. The two-color LED flashlight is ideal for any indoor and outdoor illumination. Its multi functions make Astro Aimer a very useful tool for astronomers, educators, hikers, campers, any outdoor goers, rescuers, law enforcement, military, CSI laser investigation tools and many others.


Factory Tuned High Output Green Laser with Automatic Power Control Circuit

True 5mW high power green laser, 532nm wavelength. Green laser is 20 times brighter than red laser at the same output power as perceived by human eyes. The extremely visible green laser line allows an audience in about 3 meter radius around you to clearly trace the laser line to the intended star.

Our Astro Aimer G3 has a built-in feedback circuit that constantly monitors the laser output power to keep it stable. The control allows the laser to operate stably under cold or warm ambient temperatures.


Laser ON Light Indicator

When the laser is turned on, a blue LED light under the laser switch glows dimly to signal you the device is on, so you will not accidentally point the laser to others or yourself (as shown above).


Variable Brightness Modes Red LED

There are total of 3 brightness modes. Low and intermediate modes are for map reading. High brightness mode (4,000 mcd) is for night illumination without disrupting other stargazers' dark-adapted vision. Red-light modes are activated by turning front flashlight bezel to the left.


3 High Efficient White LEDs

Three white LEDs provide true color and bright illumination (apx. 21,000 mcd total), the best tool for packing up, searching for lost items, identifying colored items, and field illumination. Activate the white light by turning front flashlight bezel to the right.

Our voltage regulated power control circuit keeps both Red and White LEDs performing at a constant brightness. The circuitry keeps the LEDs operating at maximum brightness until a minimum voltage cut off point (4 volt). LED brightness does not decay according to the battery drain as with the other battery powered flashlights.

In addition, you may turn ON either of the LED flashlights in combination with the activated green laser to pin point an illuminated object. This feature is useful especially when the object is large, which requires additional lighting for better visual confirmation.


Knurled LED Flashlight Switch Control

The knurled flashlight cap can be easily operated with a thick glove on a cold night. Also distinguishable detents identify each light mode to help you operate in the dark.


Easy Telescope Aiming Adjustment

Our time delayed laser switch frees both hands for telescope aiming without having to hold the laser ON button as with other green pointers. Please see the How to Align Your Astro Aimer with Your Telescope for details.


Universal Mounting

- 1" diameter fits most existing 6x30 finder scope mounts and our TLM02-MT laser mount.
