Typical dive canisters are rated for much deeper. The McMurdo is rated to 450 ft. giving plenty of safety margin.


Fastfind, Fastfind Plus and FastFind Max G PLBs

The McMurdo PLB Dive Canister Page says their aluminum canister is designed (and tested) to protect the McMurdo Fastfind PLB down to 150 meter (500 ft / 15 atmospheres) depth , so it certainly does seem like a good choice for a diver with the larger versions of the McMurdo Fastfind PLB, but if you have the smaller 200/210 model, see the PVC model below. It took me a while to find the McMurdo Fast Find PLB Dive Canister manual. This page says it will also hold the GME MT410/MT410G but not the KANNAD and ACR PLBs.

The Landfall Page says it is designed for the Fastfind, Fastfind Plus and FastFind Max G PLBs, and is slightly cheaper than the PLB itself. This page has what seems to be the same unit (same 150m depth cite), though they call it a "Revere(R) Dive Canister, with some larger images of the unit, a slightly lower price, and says the unit is 6.5"x3.75"diameter, adds 1 lb positive buoyancy. This vendor cautions that the Fastfind PLB must have the -20deg C battery, and this page is more specific about the " -20 deg C Non Hazardous Lithium Battery". This site has a nice photo I didn't see at the other sites, and also mentions the battery compatibility issue.

Fast Find 200/210

McMurdo recommends a cheaper canister for the smaller Fast Find 200/210 ( the 210 is the new lightweight unit Doug Ritter reviewed here ) which is "depth rated to 180 metres", is PVC rather than aluminum, and positive buoyancy with the PLB in it, which seems like a nice feature. I'd prefer a more visible color than black - preferably retroreflective so I can locate it with a flashlight at night or signal mirror by day, but some SOLAS retroreflective tape around the unit might address that. This McMurdo page says that unit is only available from Custom Divers. It is also a lot cheaper - the equivalent of $113 vs the $286 street price for the McMurdo canister. They also sell replacement O-rings and suggest you change them each season.

The McMurdo Fast Find 210 web page has a link to download the manual, and shows both the aluminum and PVC canisters on its accessories page.

Actualy this looks like a great backup plan, but I would still have another backup plan past that like a PLB that can go diving with me just in case this doesn't work

I'm no diver, but I did some poking around.

There is a nice, quite detailed article on the Nautilus Lifeline here: Alert Diver Online.

There's a good summary of the popular diving "backup plan" hardware at the Scuba STAR (Safety Tracking and Reporting) website.

On that site, they present the results of a number of their (quite interesting) diver safety surveys, but the most pertinent one to the Nautilus is here: Search this page for the "DEC/JAN '09 SAFETY SURVEY: Surface Signaling Equipment"

95% of the respondents indicated that they have needed urgent/abnormal pickup at least once (which I infer means they needed to use some of the hardware below). { I think this is an "opt-in" survey, so there is probably some selection bias - those who have had problems might be more likely to respond to the survey).

In summary, the signaling devices the responding divers carried most often (from most to least common) were:
Safety Sausage (nearly universal), whistle, flashlight, signal mirror, air horn and strobe.

What they most commonly actually used (from most to least common) were:
Safety Sausage, (whistle or flashlight) (2-way tie), (signal mirror | air horn | strobe) (3-way tie).

-----------
To indulge in my particular focus: it looks like about 1 in 3.5 signal mirror carriers received specialized training in their use, and no-one reported a signal mirror malfunction or failure.

(There's lots more info in the survey results - I encourage those interested to read the full article to get it w/o my filtering.)
