Yeah I quiet often wear a diaper when I'm going on a long dive, as do my dive buddies. Ever peed in a dry suit? Once and you probably won't ever do it again!
A very impotent service you provided, probably just as well with that pay-load….the consequences of premature whatsdowesay would have been unthinkable….not that we would be debating it otherwise now.i always took a submarine along while diving..... (i liked staying dry, and warm; grin.. giggles)
For me, I like to use it with dive with drysuit. But after an serious motorbike accident, I have to use foley catheter with a urine bag. I have try to connect the foley catheter direct to the p-valve. It work! But also diaper ^^
About foley cath directly to the P-Valve:
Just make REALLY SURE that the unidirection flow-back protection WORKS...
Also be aware, that you potentially create a very unsterile catheter environment, with some serious risks involved...
If you don't mind me asking:
Why do you wear an indwelling catheter (sound like permanent)?
Can you cope with intermittent catheters?
(I'm just asking, cause usually the indwelling ones are prone to cause a load of problems in prolonged use...)
