I have a sportys E6B for sale that was useful for my ATP written exam. I’d recommend it or something similar for any of you soon to be new hires about to get your ATP. I paid 80 bucks for it but would sell it for 50 if I can leave it for you in the sea or Pdx crew room or meet you to hand it off. Perfect condition with original packaging though I did highlight a few of the functions in the instruction book that I found useful for the atp while studying Shepard Air. PM me if interested.
