cvchief: Thanks ! I've been to Cozumel before; know where that is. I will contact them. I like the 'spray and pray' method! Also, thanks for being the only one here to actually ANSWER my question rather than try to critique my diving and buoyancy without knowing anything about me.
Can you please show me where I critiqued you? You have no information in your profile other than you have been certified for 6 - 10 years, - which means nothing to anyone here - for all we know, you could have been certified and only dove once since certification - so don't assume that anyone here knows that you have an "advanced card" - which also tells us nothing about your experience!
In fact, I SPECIFICALLY SAID: "I don't know your dive experience" - and followed that with "...UNLESS you are comfortable..." again qualifying that I have no idea what your diving experience is - so left that up to you. I will not apologize for not being a mind reader!
Furthermore, I did answer your question about Armando AND suggested that you check with your selected dive shop for rental cameras. There are VERY, VERY few places that rent cameras these days - some dive shops may have one or two on hand, but there is not a big market or advertising for them.
I'll add, that if you have a little Canon or Sony type point and shoot, check with B & H Photo online - they carry very affordable housings for A LOT of those cameras - they are model specific, so just make sure you are getting the right one. They usually run right at $200 or less, which would be less than renting a camera for the week anywhere. Won't help for this trip as I just noticed your dates, but something to consider for next trip.
Just as we don't know anything about your diving experience, you don't know anything about the regulars here that are trying to help and answer your questions, so the courtesy goes both ways!
