Looking at two Par Meters the Apogee SQ-520 and the BioTek Marine BTM3000 that seems to be made by Apogee. The SQ-520 suppose to be full spectrum and have a wider range and is $345. The BTM3000 is around $190. Both are USB and connect to a computer.
Is the SQ-520 with full spectrum really worth the price difference?
Thanks for the help
