Apecs 2.5 HUD sequence

denismc66 · 16th October 2007, 14:43

The HUD sequence for Apecs 2.5 uses 3 long flashes for Po2 over 1.5. I want to know if people find that these 3 flashes of green are sufficient to alert you to high PO2 and i wonder if a different colour such as amber would give a better warning. I also worry that i or more likely an o.c buddy would mistake these 3 flashes for a PO2 of 1.1

About the colours, well, i find the colors to be difficult to distinguish when i am in very clear water, but as soon as i get deeper or in dark waters there is no problem seing the difference.
About the buddy... Well anyone that looks on the hud for more than one minute will quickly realize that the pauce between each cell is mush shorter than the switch to a new sequence.

Don't you mean it uses one long green flash for a PO2 over 1.5?

It is letting you know all three cells are 1.5 or greater when you get three together.

I like it personally. Much easier to distinguish at a glance what's going on. I don't think another colour is a good idea personally. Green high, red low, orange bang on 1.0

No. I meant exactly what I said. A long green flash indicates a PO2 >= 1.5 from a cell. The fact he sees three, one after the other, is that the HUD is showing the state of the three cells individually.

IMO the short and long flashes are easy to distinguish.

Long flash, long flash, long flash, break - all cells >= 1.5

Short flash, short flash, short flash, break - all cells 1.1

I'm not really concerned what my OC buddy thinks. The information is for me to act on.

Seems what we have here is a failure to communicate

I don't disagree with you by the way as to the two being easy to distinguish - I'm just clarifying that you and him are basically saying the same thing different ways.

I put it down to a failure to understand....but then I would, wouldn't I?

In my first post I was trying to point out the one long green flash is the indicator of a PO2 greater than 1.5, not three long green flashes. Picky maybe.

I think you'll find I'm right.

Dive safe.

Maybe i worded it wrong. A PO2 over 1.5 will give a long green flash for each cell hence 3 long flashes followed by a gap of 5 secs.

I'll quote from the Apecs 2.5 manual - "The system is very simple and is more complex to explain than to interpret"
