Inspiration MOD

hex · 9th October 2006, 14:58

Hi,

I have a question concerning the maximum operating depth of the Inpiration. I want to use it in the future for wrecks in depths between 100 and 150 m. Are there any problems with the Inspiration which occur at these depths or can I use it safely.

thanks for your help

Rich Stevenson has taken his to 153m on the Carpathia
See LINK

This is from the specification sheet for the unit from AP:

40m - max. Depth with air diluent.
100m - max. Depth at which all rebreather parameters are proven: CO2 endurance, O2 control and work of breathing.
100m - the limit of the CE approval.
110m - max. Depth at which the work of breathing has been tested using Trimix diluent.
150m - max. Depth at which the work of breathing has been tested with an Heliox diluent.
160m - Depth at which all components are pressure tested during type approval (not during production).

WARNING! Diving deeper than 100m carries the following additional risks.

Deeper than 100m: CO2 endurance unknown.
Deeper than 100m: Onboard decompression invalid.
Deeper than 110m: Work of breathing with a Trimix diluent unknown.
Deeper than 130m: Depth gauge inaccurate.
Deeper than 150m: Work of breathing with an Heliox diluent unknown.
Deeper than 160m: Structural integrity of components unknown - the air cavity within the buzzer will implode eventually, and other components may fail.

now Simon,

Admit it - how deep hav you taken yours to?

Thanks for your help,

I was asking, because I'm interested in diving the Carpathia.

Make sure your heart is being checked before the dive !

Hi Hex,

Being based in Germany(?) you might like to know of the Triple world record attempt in deep diving with a closed circuit rebreather Chris Ullmann (Germany), Manfred Führmann (Germany) und Volker Clausen (Germany) on the 21.08.2003 in Safaga/Egypt. All three divers safely conducted the dive and reached a confirmed depth of 224.5 metres. This was on inspirations.

However on every unit the buzzers imploded after about 180m causing a critical short and dragging the power below the "brown out" threshold. The unit resets, tries to power the buzzer as it does when you switch on, the power shorts, the voltage drops below the brown out value the unit resets and so on and so on. So the screen shows the first display, goes blank, shows the first display, goes blank. Etc., ad infinitum. Also certain minature 20mm contents guages implode about 110m.

You'll be fine on the Carpathia with an Inspo., it's the weather that will stuff you!

Have a good dive, if you get good conditions there will be enough daylight for you to read your instruments at 153m without switching your tourch on.

Regards,
The Penguine

Are you sure the contents gauges will implode past 110m ? Can you say this from your experience ? Has anyone here taken theirs deeper, think so!

I think he ment some small gauges don't take the pressure beyond 110m. He did not mean YBOD ones.
