Hi guys.

I have decided to embark upon my first laser pointer build and so would like a laser power meter.

I am stuck for choice between the laserbee ax and the 3.7w usb models.

The ax has a zeroing feature (will i ever need to use this?) and a display however it is only rated up to 3.1w whereas the usb version is rated up to 3.7w.

I cant imagine me building a laser that powerful anytime soon however im thinking for future use the extra 600mw may be good to have.

Which do you guys think will be a better option?

All advice greatly appreciated.
