I've had my Wisdom 2 for almost 2 years now and this has always kind of bugged me. I would like to know if there is a way to shut it off after a day of diving, instead of it sitting there killing my battery for 24 hours in "fly" mode till it shuts itself off. I have read the manual multiple times, and have been unable to find anything. Not sure if this is just a safety feature, so it cant be accidentally shut off while diving. I would just like to know if this feature is available.
