Elite T3 memory capacity

[Frito Bandito]

I finally got my ACI data moved from the desktop to the laptop. Now I want to make the most of the portable setup, without taking the laptop on the boat.

How many minutes of diving can I do before it loses dives? The first time I used the computer I was on a week long live aboard trip. I had set it on 2 second interval sampling rate. When I got home it only had 2 dives in memory.

Next week I'll be doing a week of boat dives again, but they will only be 2-tank day trips. I'd like to crank it back up to the 2 second interval, but I don't know how close I came to filling memory at the end of my first experience.

Ideally I would like the parameters T, D, and S in the formula:

T > xD + yS

Where:

T = total available dive log memory
x = number of dives
D = Maximum memory used per dive
y = number of samples
S = Maximum memory used per sample

That way I could juggle x and y if the first dive went long, etc. This would let me make maximum use of the computer's memory

I don't know about a formula per se, but I'm at 30 dives and counting (most of my dives are
between 35 and 50 minutes) set at 15 sec interval. I think it is advertised to store 24 dives.

2 sec sampling seems excessive - what is the goal of that much data? Most of the divers I talk to
run 15 or 30 sec sample rates. At 15 I get a very reasonable profile graph of my dive and more on-board history than advertised.

Go to Aeris website then go to T3 computer and click on spec and you will find the answer.

I agree with Sladerer. My T3 is set for 15 sec sampling. This is more than adequate to create an excellent profile with lots of extra data.

 

[Frito Bandito]

I've been using 15 second interval and you all are right, that seems to be adequate.

There are a couple of problems though. Every couple of dives the history shows one to five "spikes" where it seems like I jumped up 10-30 feet for a sample or two and then continued my normal profile. It does this without making note of a too-fast ascent. Is this a bug in the T3's logging, the transfer between the T3 and the PC, or the PC's logging? The lack of the too-fast alarm makes me think the problem is with the PC software.

Hard to say for sure - my first ET3 would drop me off the depth chart when it lost the air pressure
signal. It might be worth a call to Aeris. They wound up shipping me a new DC because of this
and the DTR table in the DC being off by one ATM.

 

[Frito Bandito]

I should probably call Aeris. The temperature also seems to be consistently low by a few degrees.

was just looking this up the other day on aeris. i did a compare computers and found that if i remember right it will store 40 hours of data at 30 second sample rate.
here is the link

looks like 110 hours ar 60 sec sample rate.
