Must have for THOR H2 long distances

This is a must have for the THOR H2 for long distance. The beam expander makes the dot smaller at larger distances and it makes a huge difference!


Didn’t really know what the exact purpose of the magnifier was being that I’m kind of new to laser pointers, but from what I read it was a must and I’m glad I bought it. It really does make a huge difference and I love how you can focus the beam in reverse when using the magnifier, it starts off as a wide beam and when you focus your laser pointer with the magnifier on the beam begins to narrow the farther you point. It’s great for trying to get a small dot on a further distance. I would definitely recommend it.

Great performance enhancing

It's works amazing. I just want to get another expanded. With higher magnification my laser pointer. Works so much better than without it

solid equipment that feels well built. .

It does get a little loose though where the seal wears down. I would add a second seat for another seal to stop it from getting loose and add some parafin wax to stop seal rubber from wearing down

Can__ really tell the difference

Maybe it__ just me but the expander seems to make the beam less focused and thus not able to burn stuff as good. To be honest, there are too many things to adjust to get a focused beam in my opinion. In any case, the laser does burn stuff without the expander so overall I__ happy.
