why analog?

Two SPG's (in my opinion) on the same tank is overkill. Two BT's -- well, it depends on the dive I guess. For recreational or "shallow" tech dive, not necessary.

Ah... I thinks it's clear from the original post that he meant the Cobra as his one and only SPG device. The redundancy would pertain only to its computer/bottom-timer capability.

Relative to DIR, I've already posted that if he intends to go DIR he should adhere to its standards.

Well, he is obviously free to do whatever
I would not use such a device, and have no need for it.

I try to choose a reasonable level of redundancy mixed with practicality and find the DIR approach gives me that.

YMMV

TomP, why can't he look at DIR and choose the parts of it he likes, and not have to label himself as full on DIR and follow every single standard.

While that is somewhat possible, a lot of things in DIR are inter-related (gas choice affects ascent profile, repetitive diving profiles, long hose/bungee backup affects OOA procedures, and ideally owning a canister light etc. etc.)

so I think it is possible to pick and choose some things (as long as you practice with them if they change your gear or way of diving), but you do have to be careful with what you pick & choose.

absolutely they need to practice with any changes in configuration and procedures that they adopt. But how many people that consider themselves DIR have never actually taken a GUE course?

First, since I'm not DIR I hesitate to comment on what is or isn't DIR and Limeyx covered it fairly well. In a nutshell, standardization is a fundamental principle of simplicity. Once you introduce change you no longer have standarization and things become more complex. Where then do you draw the line?

To be clear, this is not to say that anyone should not adopt those aspects [probably most] of DIR that work for them. But, if becoming a DIR diver is the goal then it should be embraced in its entirety.

I honestly dont see where he said he was def planning on going DIR.

He didn't and I didn't mean to suggest that he did. He asked if using his Cobra as an SPG was DIR. Therefore, I inferred that he might be considering DIR.

 

[Cheekymonkey]

ah, alrighty

 

[scuberd]

let me settle this:
My question was from a tech diving standpoint primarily, but also I wanted some input from any die-hard DIR guys out there.

Thanks for such a lively debate, it's been informative and entertaining.
