This is for Cathy, but you guys are free to order your own, patent pending, i don't accept paypal hehehehe

It's a dirt-cheap way to help secure your $$$ dive comp... the inspiration came to me when i was buying my mosquito and a guy walked in asking to buy a stinger because it fell off the boat in apo reef! - i thought to myself: "hell no!"

so i rigged up this simple DCSS (dive comp security system) and after i'll discuss how it's used

first find a bungee cellphone lanyard (these are available anywhere, mine was an expensive P50!). i suggest this vs. regular dive shop bungee as this one already comes complete with a quick release clip and nylon cord.

i used mine out-of-the-box until the cheap metal corroded to nothing, this took several dives. if you want to avoid the hassle, pry the metal clip away from the bungee. loop and secure the bungee with zip ties; burn off the ends to avoid fraying

i purposely left my QR clip hanging on the metal ring, it has rust right now, and i will soon replace this with either a sturdier keychain ring or zip tie...

loop the nylon cord around the DC buckle the same way it would go around a cellphone (these nylon cords are designed to carry the weight of a dangling cellphone, they're pretty strong)

when donning/ doffing a wetsuit or rashguard, you can unclip the computer (recommended in a "safe" place) or let the computer hang, grip it in your hand and wear your exposure suit as normal

the computer can be detached from the system via the quick release when you're rinsing it or wish to put it aside/away at the end of a dive day

the above item is available on ebay.ph for P500 (includes delivery w/in metro areas) hehehehe

hope you never have to walk into a shop looking to replace a sunken computer!

jonix:
what for? does the strap come off by itself?
it's just for "your" peace of mind it won't fall off your wrist...suggest the line be tied to the boat. If the diver is lost the unit can be retrieved/saved. And the diver? goodbye...
 
Jag - The plastic clip is not DIR! That is a failure point right there! What were you thinking? :D

great idea bro!
 
Jai beat me to it, stupid meetings! Rather than the "plastic failure point of death", we can swap in a stainless steel double-ended snap. It'll be just a bit bulkier (4 inches vs. 1 inch) but it'll be secure. :wink:

A lot of the losses occur because the strap ends at the pin. If you lose one pin, the entire strap flops loose and the computer gets lost. You can also replace the strap with something like this strap so that if one pin gets lost, you don't lose the computer.

@jai: that's ok... yo no hablo "DIR" hehehehehehe

@eric: it's really designed to give you the alternative of removing the computer from your wrist when stripping down from your wetsuit... underwater your computer is generally safe and secure... but remove it and place somewhere on a dive boat and it can get nudged into the drink, used as a rollguard by a tank or stepped on by an errant k diver...

I understand what you're getting at and think it's fine for that purpose, just that other related problems exist too.
