The 1 to 5 min i was refering to above was the time available before the boat went down, not how long it takes to get a EPIRB signal out. My unit does have the built in GPS and the ability to be connected to my onboard GPS so the the first signal could contain my current position. It would be ideal to have this connected however i do not see that happening in the near future for me. If when the poop hits the fan i and my crew end up in my dinghy with the EPIRB transmitting within 1 mile of me i will consider myself lucky. I if also have my ditch bag with handheld VHF and all the other goodies, well thats iceing on the cake. In my neck of the woods i would expect a rescue within 6 hours with a working EPIRB.

In that situation we all hope never happens, isn`t the best place for the EPIRB beside you in the dinghy or raft, not 1 mile away still with the boat or floating/drifting where it sank?

Securing my epirb is not as easy as removing it from the mounting bracket and hiding it on the boat. My McMurdo has a water deactivation magnet built into the mounting bracket (I think all McMurdo's do). I had my epirb activate while the boat was in Guatemala and I was in the states, received 2 calls from the Coast Guard and had to replace the battery. The problem was caused by storing the epirb while it was removed from it's mounting bracket, the device that activates the unit when it is submerged turned the unit on. I had stored it under a drawer, in a ziploc, in a dry location on the boat. I now remove the bracket to store/hide the epirb. Something to consider when choosing mounting locations.

PSNEELD,

I respectivly disagree. I have been involved in many SAR and the extra time could mean the differance between living and drowning.
Go ahead and disagree .... as on scene commander or SAR coordinator for thousands of SAR cases....I know and you should too that the average GPIRB 99.9 percent of the time is sending position data long before the SAR unit even gets underway. There are lots of reasons there's confusion in the early stages of launch but I don't ever think it was because of the difference between the 2 types of GPIRBs.

The entire COSPAT/SARSAT system was made to work just fine without GPS even being in the equation..and the statistical number for SAR cases where those minutes REALLY count is miniscule.

More importantly..if you are betting your life on a few minutes...then your survival plan needs reworking...please don't make me list all the survival schools, safety at sea seminars I've attended or taught at....

or how you mount it...good point...there are many false alarms because of just what you said or them falling out of the brackets on commercial vessels.

The British on one of their website go into a good discussion of how to package them for shipping/storing just so accidental starts don't initiate SAR proceedure. My personal favorite was locating a false alarm and following the FEDEX truck up the Atlantic City Expressway on evening...

Mounted. Put it on outside of fly bridge in Radar Arch. Can grab if needed and able to deploy auto if required without obstacle

Depends on the model too. LOL First time I turned off GPS, then a few minutes later the VHF started to squacking it scare the crap out me...

I therefore put mine right next to the pilot door, with activation diagrams/instructions now afixed beside it. (added since photo taken).

Peter,

Thanks for the feedback. As you can see it has a cover to seal it from the elements. So I am not concerned about the elements. It is high enough up that thief would have to board my boat and enter the Sundeck and then the fly bridge all which are locked. Theft is not a large problem in my opinion because all EPIRBS are required to be registered by a unique UIN. If it is stolen I can check with NOAA regarding that UIN and they could assist in the recovery.

I chose this location because I primarily operate from the fly bridge and the EPIRB activation would be as a matter of course at my position on the flying bridge.

I also reason that if the vessel broaches and capsizes the location is deep enough that the hydrostatic release will pop it out and transmit.

I would be concerned with your location. If it is not grabbed by a crew member it won't have a clear Line of sight to transmit.

Thanks for your input.
