First off, I know nothing about laser pointers so I joined this forum to get your help. I bought a green laser pointer from Dragon Lasers (in China) but it died and the company no longer stocks the Viper. My uses for this tool are 1) birding watching to point out a bird (I seek a laser for day time use and some night time use for owling), and 2) looking at constellations (night time use). I live in Mexico and haven't a clue where to find one here but I will be in Arizona the last half of this month and want to bring one back with me. Thanks in advance for any suggestions.
