Hello All, I just purchased a new Perdix 2 a couple weeks ago. I have done 6 dives with it so far and the bottom temperatures are way off. I have several dives at 60 feet in freshwater rock query that the bottom temp is 56 degrees. Several of my dive buddies registered this temperature on their dive computers which are different brands. We were at that temp for about 10 min. Mine only registers 71 degrees. The surface temp water is about 88 and surface air 100-110 here in Texas. Any ideas why the bottom temps are not accurate but surface temps seem to be. Does it normally take more than 10 min for it to update the proper bottom temp?
