Priced between $19-$40 for cheapies on the web and .1, 1, 3 and 5mw laser power rating.
Is there any point in getting the green laser at 532nm?
What Mw rating/power level should I get?
Can the laser be used for other optical tests?
Thanks
Steve

Steve, the purchase and use of handheld laser pointers with output over 1mW in ACT is regulated and are deemed as prohibited weapons. There is however an available exemption from the Firearms Registrar (AFP-ACT) that allows the use of more powerful laser pointers by members of an approved astronomy society in connection with the activity.
