Dive Alert Air Horns ???

[detroit diver]

I would hate to attach anything to my inflator hose, other than the inflator. But I can see a use while drift diving. Can these be attached on the surface after inflating your wing/bc?

I've owned one for many years but never had to use it (well, almost once when a couple of divers on my team decided to end the dive and ascend away from the up line...the current took us quite a ways from the boat by the time we surfaced...that ever happen to you Jack?)...I keep it in my pocket though (made a loop of shock cord that fits over it and use a small bolt snap to attach to inside of pocket bungee). I check it before leaving for the charter to ensure it works properly. I know there are many divers who swear by them and would not think of doing an open ocean/Great Lake dive w/o something like this....(to include me.)

Ya know, I was thinking of exactly that same dive when I wrote that last post! Couldn't find that darn upline......!!

I have the same concern, that's why I was concidering putting it on its own LP Hose and tucking it away somewhere or clipping it to a D-Ring. Any comments ?

Yeh. Just another potential failure point. Why not just stick it in your pocket and use it IF you have to? That's what I think I'll do. No need to have it hanging around for the once in a millenium time I'll need it. I'll just put it in my pocket when I do a lake dive, or drift dive.

edit: Or I'll just hang around with Brando and watch him laugh at me!

any suggestions on cave line vs. zip ties and double enders vs. single enders for rigging a DA for clipping?

I've been steered away from zip ties. My guess is a single bolt snap will do as you are on the surface while using it. With a DE, you will need to hook up some kind of loop to attach/detach to/from. With the bolt snap, it would already be attached to the DA, so you'd just unclip it from your bungee loop in your pocket.

To be honest with you, I've never had a reason to use mine.

I used mine often, primarily to annoy others.

I was using it tonight in the apartment complex parking lot.

I told the neighbors that my boat pickup was late.

Works like a charm.

Annoying others, that is.

Keep in mind, if you're leeward, your chances of being heard on the boat decrease dramatically.

A careful analysis of the potential failure point and the potential advantage of having it already in place might lead you to carry it in place.

In the unlikely failure mode of it somehow blowing apart and starting to leak gas, you simply disconnect it the same way you would a stuck inflator.

OTOH, I can easily envision a lot of circumstances where, if you want to use the Dive Alert, that you want to use it NOW! w/o having to dig it out of a pocket and mount it while simultaneously taking care of some emergency situation.


YMMV.

Failure point, that's a little far fetched. As Charlie99 points out the DiveAlert needs to be on your hose all the time. Here's a very simple scenario- Your buddy makes a rapid ascent, you don't know why. When you ascend and find him on the surface, say not breathing, you lay on the DA and just about everybody within a mile will know you're looking for some assistance. You simply don't or shouldn't take the time to hook it up.
The ONLY time I don't have it attached is when I'm cave diving, and that's where I am more concerned with failure points. Get a DiveAlert and have it attached anytime your diving, even in a lake or river.-M
