Dear Zak,
I'm new on this sport and some friend gave me his old dive computer. A Mares surveyor, i know it's old enough but i can't affort anything else at the moment. I tried to download the zip file of it's users manual you post so long ago but i was unable to do so, because the file is no longer availiable. I would be very happy if you could sent it to my mail so i can read it and use this computer the best possible way i can.
Thank you in advance for your time and your answer,
Aristotelis.
