Hey, I am using SCUBA PRO CHROMIS since 2015, but recently I noticed I have lost all the dive record of previous year, usually we dives in between Sep-Apr in Karachi Pakistan due to weather limitation and my dive logs of 2015-2016 totally lost... the battery was changed in last season i.e. during 2015-2016 season but as I remember after that all logs was intact perfectly which are now not shown on dive computer... can anybody tell me the limitation of Chromis dive log memory or the lost accrued because of battery changing ? Please do reply at this thread or I'm available on WhatsApp : +92-300-9236041 advice is much needed. Regards. KHIZAR
