Just returned. Diving at Cano island was really good. Not exceptional, but well above average. In two dives we saw white tipped reef sharks, 1 bull shark, manta rays up close, a number of other rays, lots of fish schools, and some big jacks and other large ocean fish. Nice to see some...

Hi, I've tried searching but haven't come up with much. I'll be in Drake bay for a couple days mostly visiting corcovado. I'll have one day to either snorkle or dive at Cano island. It's the first week of April. I seem to read a lot of mixed reviews of Cano island diving. Is it worth...

This is one of the few forums that we can actually have a discussion without turning into name calling and childish behavior. I like it! I'm surprised there isn't a single unit that will do a full air analysis. The actual CO sensor is only $10 or so. I'm not sure what it would take to...

Is it fair to assume that you don't check your nitrox mix either? If you do I'd be interested in the logic of checking the mix but not the CO.

I believe there's a bit more to the equation than simply looking at PPM equivalent at depth. There is also an issue of how the CO is absorbed under pressure. CO will attach to hemoglobin much easier than Oxygen. My general understanding is that at depth, the oxygen concentration is greater...

I think the same reasoning that we use dive computers for is equally applicable to CO. I could trust the DM to dive a safe profile. They do it every day and 99.999% of the time, the guests don't get bent. I could probably dive with any reputable dive shop without a computer and never take a...

I believe the tank is probably emptied and sent back to refill with new air. It was set aside on our boat not to be used. Fortunately the dive op stocked the boat with a few extra tanks. For all I know it was left on the boat for the next dive group, but I kinda doubt it. I think you could...

Dandydon, You may not realize it, but I think your testing and reporting has gone a long way toward the safety relating to CO. Were it not for reading through your experiences a year or two ago I would not have really been aware that it might be an issue. I bought the toxiRAE after reading...

I was with a group in Cancun for the week and we went over on Sunday to Coz. to dive. The Dive op was Deep Blue. I have a ToxiRAE3 CO sensor. I have not calibrated recently, but it is about 1 year old and is stored in an air tight container in a wine cellar when not in use to prolong the...

That's interesting. I was going by the Paypal "Philippines cross border transaction fee" schedule. As far as conversion rate, does paypal cheat you on conversion when billing in your own currency? Paypal can invoice in Php. When we looked at it they were going to invoice my paypal in...

Thanks Ali, We still had fun. The actual sea life and diving was really good. There were some some good things along with a few other "issues" with the dive resort. I'll put an objective review with pics and video in the Philippines sub-forum soon. I'm not trying to badmouth anyone. I...

Thanks for the responses! It's great to have a site like this to get some objective advice. To help clarify, the website says nothing about payment options either way. We emailed a couple resorts in the area to get quoted prices and availability. The package I understood to be basically...

I'll keep the dive op's info and location out of this for the time being, so just a generic question: Should you expect to add 7-10% to your payment if you pay by card in S.E. Asia if the country has a withholding tax or should you expect the company to include the tax in it's pricing. Basic...

I have a yellow 4' one. Only inflates from LP hose or by mouth. I use the LP hose and have never had a problem with that. You just need to be comfortable popping the hose on and off. I suppose I could add another hose just for the SMB, but I don't see any reason to do so. It's easy enough as it...

I'm not familiar with the Nautilus Lifeline enough to know if this is a plausible option or could be added, but here's a suggestion: Add a wire to a SMB that, when inflated could be connected to your lifeline as an extended range antenna. I'm not entirely familiar with radio transmission...

Is there any enforcement of the marine park rules now? I unknowingly violated the rules last week. I have a small <3" dive knife that lives on my BCD. It went with me for quite a few dives in the park. Neither my DM nor anyone else mentioned anything about it. Before reading this I had no idea...

FWIW, on our recent trip we only saw 1 lion fish. Compared to my trip to Curacao, I'm convinced that the Cozumel hunting of them is having a positive effect on the numbers. Will it eradicate them? No probably not, but there are a heck of a lot less in Cozumel than there are on other reefs...

I think you may be correct on that. They are newer mares built regs, but parts may still be hard to find. This may even mean servicing isn't an option.

I am somewhat of the same opinion as the OP regarding long or no servicing. We've owned our regs for about one year now. Mine are Dacor Eagle pro DPD, and the wife has a Mares MR12 XL. We dive about 30 dives/yr and store them in a wine cellar. (A real wine cellar made of concrete in the...

I don't maintain proper weight, trim, buoyancy etc. because my training suggested it. (And my PADI course spent 2hr a week for 12 weeks in the pool, so there was a lot of trim/buoyancy practice and training). I do it because I like to enjoy the dives. Having proper buoyancy and trim makes diving...
