i would like to buy a green laser pointer that has a METAL CASING, not plastic, that uses two AAA oy AA batteries, or rechargables with a charger, that can be seen in broad daylight on tree limbs. I assume it will be more powerful than 5mw. I do not want to pay more than $20.00, but would consider doing so if absolutely necessary. Does anyone have a link or direction that won't be removed?
