After looking at battery replacement costs for some time i thought stuff it. So replaced the  batteries myself. Pretty simple as designed to be user opened for decommissioning. Batteries easily obtain

The are Country Specific, so they the right rescue centre get the alarm. Our Boat came with an Ozzie one and it could not be registered with MNZ as it alerts Ozzie if activated. We brought a NZ o

because they charge more to replace the battery pack, seals and test in nz than it costs to buy a new epirb

i think a friend paid $550? to get his old batteries replaced and i don't think the epirb even has a gps chip, he was annoyed when he went to pick it up and they sort of said they shouldn't have done the work without telling him it would cost more than buying a new and better(gps) unit  

some people do a diy battery replacement but you wouldn't bother if it wasn't a gps epirb

As new, never been wet or used in anger. 

It amazes me in this day and age to be told it is uneconomical to replace the battery.

Why?

That's pretty bad of them, it sends the wrong message. They should be promoting that this unit is old technology, that there are much better solutions AND that a certified battery change will cost the same as a new and better unit.  FYI, the MT403 doesn't have a GNSS (aka GPS) receiver.  Also, a large number of MT403's were recalled due to a design fault.

If you're not going off shore, or need Cat 1/2 then you might consider a PLB instead of a EPIRB.  All of our crew have PLBs in their life jackets.  We don't have a boat EPIRB.

I was told $250 to replace the battery on my $500 PLB.

You can get PLB's with 7 yr battery life now for $450 if you shop around (or watch for specials). McMurdo I think the brand is that do 7 yrs.

The main difference is a PLB doesn't float upright by itself, an EPIRB does. With the type of sailing I do, a PLB worn on the person is far more valuable.

I probably shouldn't mention this bit, but the battery needs to last 48 hrs. If you aren't racing, I'm sure you can use an out of date unit for a while. Its still going to give a signal, just 6 hrs say, instead of 48 hrs. (I'm only doing Coastal / Gulf cruising) anything longer and I'd just get a new unit. But I'd replace your unit if it's not GPS enabled. That bit is a no brainer.

afaik there are 3 differences design differences that differentiate between plb + epirb

1. epirb must float antenna up..........so is 2x? as large as plb to contain sufficient air volume....my gme mt410 is still pocket-able which is great as it can be carried in a lifejacket pocket or any jacket pocket when taken on land beyond phone coverage  

2. epirb must have 48hrs battery life on continuous transmit, plb 24hrs

3. epirb must have strobe

Keep an eye on what country the EPIRB will be registered in, if you are looking for an internet deal. There are some very cheap name brand units available, but they would be registered in a third country, not NZ Marine Rescue Centre. Two countries I saw were the UK and Au, which aren't too bad. Guatamala might be a problem though. But if you activated it, and you are in a hurry to get rescued, you are adding a layer of logistics and bureaucracy before your signal gets to someone in NZ with the authority to launch a helo for you...

Are they really produced market specific? I would have thought registering the epirb with beacons.org.nz would make where it came from irrelevant?
