Which compact spotter is best 600 or under? vortex razor 11-33x50, the athlon cronus 12-36x50, Hawke Endurance ED, Nikon fieldscope ED or is there something I'm missing or If I jump to the 65mm it would be the Vangaurd Endevor ED or the Athlon Area. If there sweet scope I'm missing let me know I'll give it a look. thanks all for the advice and experience.
