What Laser Pointer Is Good For The Following Purposes?

Hello everybody. I would like to know which laser pointer and of what color are good for DIY home jobs where i need to mark places for drilling/hammering nails and other stuff in the daylight.

Second purpose is to point at night to show specific locations, directions and landmarks in the night. Third purpose which is least important is presentations that maybe i will be doing in the future.

I live in Israel so i don't know restrictions, but i want laser for $15 or better yet less. I heard that 5mW are not good in daylight so i guess i would need something like 15mW?

Thanks!

I think a 5mW green/red would do the job pretty well.

For your 1st purpose, a 'laser level' seems to be what you need, but as these can be rather expensive (more than $15) I think you could use a pointer in coordination ( perhaps atop or affixed to) a standard level to hang pictures, align nails etc.

When it comes to pointers, green mW per mW is much brighter than red. You should be able to see the point from a 5mW green in daylight where this is more difficult with the 5mW red when outdoors (both tend to work just fine for pointing inside). You may also be able to see the beam of the 5mW green at night given there is some dust/water vapor in the air, making them great for pointing out objects. You have to be careful though, many of the cheap green pointers sold on the internet as 5mW can actually be much more powerful, in some cases 40mW+ so proper eyewear must be used whenever using one of these.

here is a link to a trusted company: Laserglow Technologies - Handheld Lasers, Alignment Lasers and Lab / OEM Lasers, while being more expensive the stated output will be accurate and general quality of the laser will be much better than the cheap amazon or ebay items.

good luck!
