Sorry to exhume this old thread but I ended up here looking for reviews of the 502 as I was looking to buy a cheap lightweight spotter to mess around with this year before I eventually buy a Kowa 554. Did you ever end up getting rid of that 502? (I would’ve sent a PM but don’t have privileges yet as I am new).I have the 502 and might consider selling them if interested. I am leaning to go with just 12x binos and leave all other optics at home.
