I recently completed a dive with max depth about 105' with most of the dive ranging between 85' and 100'. I was diving with 2 computers - a Tusa IQ-800 and an older Oceanic Data Plus. The Tusa put me in Deco while I was still in a comfortable range on the Oceanic. Both computers on SF-0. My instructions on the Tusa were to do a 3 minute Deco Stop at 10'...that depth seemed strange to me as that is shallower than even a normal Safety Stop. On my ascent I decided to do a Deep Stop for a minute at 50'. While doing this Deep Stop my Tusa started adding time to my 10' Deco Stop ..and in fact actually got up to a 5 minute Deco stop at 10'. After my minute expired at 50' I decided to do a slow ascent to about 20 - 15' and see what adjustments my computer might make. Once in that range my computer was still telling me to make a 4/5 minute Deco Stop at 10'.... so I ascended to 10 ' and hung out and sure enough I was able to wait out the 4 minutes (a big rock ledge aided in this) and then my computer gave me a 3 minute Safety Stop.
This is only my 10th dive with this Tusa IQ-800. The manual sheds no light on this. Does this seem normal to anyone out there? Anyone with any light on this? Thanks!
