Cressi computer problem

There's no such thing as descending too fast. As long as your ears can handle it you can plunge straight to to the bottom and start your dive.

Deco alarms were my second thought that occurred to me about 30 seconds after I typed my earlier response.

I never blew past a deco stop on the Leo but I've a vague memory from The Fine Manual that it may flash the down arrows and beep when you do that.

Not if you're a saturation diver working on pipelines and fiber optic cables: for those guys there very much is such a thing as descending too fast.

What is the issue for them?

Neither have I. And your memory is impeccable.

From "The Fine Manual" for the Leo:

If the decompression stage is missed by surfacing above the depth given by the computer, an alarm will sound and the down arrow of the decompression icon will flash on the display until the diver descends back to the proper depth or below it. In the opposite case, that is when the diver goes below under the stage depth by a specific amount, an arrow flashes, indicating that it is necessary to go up. The computer allows a maximum time of 2 minutes to correct this dangerous situation; during this time, the alarm will keep sounding.

OP, could this be what you were experiencing?

Google HPNS.

ISTR a thread in A&I a few years back about an entire shift killed by the op pressurizing them way too fast.

Speaking for myself:
Rapid descend is to be avoided especially the first couple of dives on diving trip. Narcosis at 20m spoil the fun.

How did your depth change with your buddy as the reference when you used the inflator/deflator in your bcd?

Hi
I was diving yesterday and turned the dive after 20 minutes, I was diving the second dive of the day to the MV Xlendi wreck in Gozo with the first dive to the Cominoland Wreck with max depth of 36.9m. This is the 8th dive in 4 days and the previous days dive were 40m and 23.6 with all other dives to a depth of less than 20 m. I encountered a problem with the descent readings on my cressi leonardo computer which was showing I was desending way to quickly but I was level with my buddy in the blue at the time. I added air to the bcd but it still showed my descent rate was to quick so I added more air, when the computer reading changed I was ascending to quick and I then deflated but again the computer reading did not change this led to me going up and down and I turned the dive and done the safety stop and abandoned after 33 mins.
At first I thought maybe I was parked and pressed the wrong inflate and deflate buttons but I dive a scubapro glide bcd with red and grey inflate and deflate buttons which are difficult to get wrong.
Has anyone else had problems with the readings on Cressi Loenardo computers or was this diver error.
Thankfully I am OK with no side affect and will not dive again on this holiday Thanks in advance

how long was your surface interval after the first dive ?
