I have an Apogee SQ-520 par meter that I would like to sell/trade. I am looking for a xr15 g6 blue and will put cash on top.

The par meter has worked great for me. It is the usb version with a long cable, so you will be able to plug it in to a computer. I would keep it, but I decided to get a mq-510 instead since my computer is in another room now.
