Product Info

Manufacturer Description

Astro Aimer G3 has all the features of Astro Aimer Gen II and the same dimensions and appearance of Astro Aimer Gen II. In addition, new Astro Aimer G3 is dust and water resistant with redesigned internal construction and an anti-reflection coated optical glass window to optimize its outdoor applications.

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. The 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.

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 Highly 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.

The HoTech Astro Aimer G3's 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 detentes identify each light mode to help you operate in the dark.

Easy Telescope Aiming Adjustment
The HoTech Astro Aimer G3's time delayed laser switch frees both hands for telescope aiming without having to hold the laser ON button as with other green pointers.

Universal Mounting
1" diameter fits most existing 6x30 finder scope mounts. No mount is included with this item.
1/4-20 standard screw hole ready for any tripod or ball mount.

Precision Machined Quality
The well crafted Astro Aimer is precision CNC-machined from aero-space grade aluminum material, and then sand blasted and anodized for a rugged and long lasting surface finish.

Extra Long Battery Life
Operated by three AAA batteries (included) providing approximately 20 hours of continuous operation.

Convenient Field Carrying
Package includes one detachable 15" adjustable strap to hang on your neck or wrist, belt clip pouch, and foam protected box for field transportation.

Dimensions and Weight
1" diameter x 5-3/4" length. 5.3 oz. with batteries.

      4.0 Green Laser and Flashlight—A Good Combo

      Pros:

      Cons:

      Comments:

      I purchased the HoTech Astro Aimer G3 - Green Laser and Flashlight, even though I already had several green lasers, several red flashlights, and several white flashlights. Having all three in one package is wonderfully convenient!

      5.0 HoTech Astro Aimer G3 Green Laser and Flashlight

      Pros:

      Adjustable Beam,Durable,Bright

      Cons:

      Comments:

      I use the Astro Aimer G3 primarily when setting up and taking down the telescope and binoculars for the evening.
      The variable 3-position red led brightness levels are very useful for keeping track of items and setting up in total darkness.
      The white led does a great job for use as a flashlight. The well-defined green laser assists in pointing out features in the night sky. Overall, an excellent light that combines white and red led's and a green laser in a well-designed package.

      2.0 Good, Bad and Ugly

      Pros:

      Adjustable Beam,Durable,Waterproof

      Cons:

      Poor Laser

      Comments:

      Good - Unsurpassed build quality, feels solid to use, white light and adjustable red light work very well for astronomy use.
      Bad - Turning the front lens to turn on the white and red lights is a 2 hand operation because the action is very stiff. I prefer the cheaper red astro light I already have because I can turn it on with one hand which is helpful at night when holding astro gear or charts.
      Ugly - When the temperature starts to cool, the laser stops functioning. I have to put it back in my pocket and warm it up with my hands, then I get a few seconds use from it again before the laser fails once more.

      5.0 Wish I had bought this long ago.

      Pros:

      Well Thought Out Design,Replaced Several Tools

      Cons:

      Comments:

      This sure streamlind the things I carry when taking the telescope out for observing the night sky. The laser is cleaner and clearer than the laser pointer I had used before. This unit is well thought out and looks very expensive and high-tech, definitely not a toy and it seems that HoTech doesn't skimp on quality. I wish I had seen this model long ago when I first bought a laser pointer for astronomy.

      5.0 Excellent gizmo

      Pros:

      Compact,Strong Construction

      Cons:

      Comments:

      Nice positive switch for the LED red/white, with good illumination red brightness levels. Much better than my Celestron red-only flashlight with a difficult to use thumbwheel. The laser seems good, although I don't have any comparator. And nice rugged feel to the unit as a whole.

      5.0 Very useful - well designed

      Pros:

      Accurate,Strong Construction

      Cons:

      Comments:

      This proved itself to be a well-designed, all-purpose light that I suspect will be my constant observing companion.

      Here what I really like about it:
      * The white beam is powerful enough to light up the work area and path for setting up, cleaning up and going back and forth to the house.
      * There are two red beams. One is powerful enough to work by without destroying your night vision - the other is significantly weaker, but just right for reading charts.
      * The laser is turned on by one button , turned off by a second - and when on the switch area glows very dimly so you know the laser is on. As for the beam itself it is easily as good as my best other laser which now is mounted on a small scope as a finder/pointer.
      * To turn on the red light you twist the bulb end of the flashlight to the left. To turn on the white light, you twist it to the right. This is significantly different and well-separated from the buttons for the laser, so you shouldn’t confuse them.

      The whole thing seems well built, comes with a nice carrying case, and a lanyard so you can wear it around your neck. I found this last extremely handy. With the white light on it lit my path while leaving my hands free to carry stuff. I also found that even in my small observatory, where I have a red light on a dimmer switch, it was easier, in most instances, to reach for the one around my neck and I did this frequently - and it meant I could direct the light exactly where I needed it.

      Very handy!
