The Astro Presenter is the first of its kind to have two laser activation features. The 5mW laser can be activated momentary during presentation by using the round toggle switch for a quick pointing. And the laser can be activated continuously with the sliding switch. Ideal to use as a star finder for a telescope or any aiming puspose. The continuous ON switch frees user's both hands to slew the telescope with the aid of the activated laser beam to the desire star without holding the laser activation switch like others.
In addition, the Astro Presenter uses the included high capacity CR123, 3V lithium battery which provides over 6 hours of continuous use battery life time. The battery operates well under a typical cold night and it has a 10 years shelf life. This is a great advantage not having to worry about changing batteries frequently in the dark like other pointers.
