Even if it is flush, it still adds to your profile in the worst possible place.

If I'm following this correctly isn't he connecting it near the middle of the torso to the crotch strap?

How is the addition of an SPG at that point affecting your profile?

It is not flush against my crotch strap...the clip is "forward "of the spg so the spg itself is about an inch to the left and above of the crotch strap...

It adds, at most, ½inch to my profile...I can live with that because it means I never have to unclip it to read it and I can see it by bending my neck...
Of course...I don´t dive that way at the moment...but I still have a hard time seeing the "entanglement hazard" as anything more than a theoretical....

When in trim, your crotch is the lowest point. Having something below that is just asking for trouble, IMO. If something is clipped to your crotch Dring and is *not* the lowest point, you are out of trim.

I'd have to see a picture of what Grazie is describing, but I am incredibly skeptical based on the laws of physics and buoyancy. I guess I'm not particularly interested, though since it is a solution in search of a problem.

I always thought it was more of a horizontal line from your knees to your shoulders, but with the arching of the back whatwith the doubles and keeping my feet high yeah its probably the crotch that is the lowest point.

So you're referring to profile as the silhouette of the diver against the water column? Like nascar drivers talk about the draft, right? Something that equates to the drag coefficient, yes?

Roughly, though I'm not concerned about a little 2inch SPG causing drag. It's catching on line and crap in the water that would concern me. It's something that doesn't need to be there since there is a better place for it, which the poster apparently agrees with since he doesn't dive that way.

This is how I visualize it as well...the crotch d-ring is lowest but so is your knees and shoulders...if it´s ok to clip things to the shoulder d-rings (backup lights comes to mind) then I don´t see what´s wrong with clipping the spg to the SAME lowest point:06:

Backup lights are held out of the way with rubber holders. An SPG will hang down via gravity. So its not the same thing.

You shouldn't be putting your crotch anywhere that line and crap accumulate though :D

At first I thought we were debating the profile differences IE Depth readings from mid hip to crotch and though geezsh wth, but now that I have a firm grasp on your argument against...

It seems that with your hands, your backup, your d/s valve, etc breaking the water column at the forward end of the silhouette the crotch might not be the lowest point anyway. I agree with your placement because I learned it that way too, but I dunno that I agree with the argument. If we're here in BSD to debate the why's please allow me to theorize...

Progressing to a new level introduces articles that protocol says attach there (Scooter, right?), its more of a don't change this or you'll impact that justification. And that is ok, DIR does it, other guys that just try to dive safe plans do it, they just don't do it the same, they say "we like" instead of "you must" but it all equates out to we do it together.
