EPIRB - 406Mhz Emergency Beacon compare (PLB)
25th Feb 2015.This review will be updated over the next 2 weeks or so with a link to the update.
15th May 2008
There are 5 406Mhz Emergency Beacon manufacturers represented in Australia, GME Electrophone, Pains Wessex, KTi, ACR and Kannad. of those two are Australian, GME Electrophone and KTi. This review is for the PLB, Personal Locating Beacon and not the EPIRBs used in a boat, or rather attached to the boat. PLBs you have tied to your Life Jacket or if you wanted to, in your pocket.
The current 121.5/243 MHz a n a l o g u e COSPAS SARSAT service will be terminated in February 2009 and only the 406 MHz digital beacon signals will be processed thereafter. Consumers have for some time recognised the major benefits of a 406 MHz over a 121.5 MHz device in faster, more accurate detection, personal identification of each beacon, reduced search area resulting in a faster more targeted response in a life threatening situation. However the prohibitive cost of 406 MHz beacons has always been an issue.
I have a problem with buying anything that is not Australian, or at least buy Australian before I buy products from overseas. There is a hierarchy of course, but anything past New Zealand are thrown into the pot and decided upon from price, quality and support etc. In saying that the Australian manufacturers, based on this review, are not second to anyone, but world class leaders, however, you have to read this review to come to your own conclusion.
As I am not in the market to buy a unit and I am wanting to give an unbiased report on the models, thus expect me to be reasonable in my judgement.
If I was to buy a PLB (Personal Locator Beacon) I would buy it based on what it was designed to do, save my life. Based on this I would want to ensure a few things first, the battery won't be flat when I go to use it, it will last long enough for Search and Rescue to find me, and is not going to suffer from being lost.
You may ask, what do I mean by "being lost", well many of you know that over the years GPS technology has improved in particular sensitivity and tracking. The newer GPS engines (for example SiRF III & MTK32) are far more robust than their predecessors by a huge amount. Anyone who has any of the older handheld and newer handheld GPS will testify this.
The first thing I look at is the battery life, which ties in with warranty. First number represents battery life in years whilst second is warranty in years.
ACR ResQFix 10/5
Pains Wessex 5/5
The second thing I look for is if it has a GPS. The difference between a unit with or without a GPS is many many square kilometres. Some suggest a 2km radius without GPS and 100 metres with. I feel far more secure knowing that if I am injured or in freezing cold water the extra accuracy means extra quick location of my position, thus make it to the hospital in time. It is interesting the accuracies that they all quote, however, I suspect the KTi Mini-Sat-G 406Mhz PLB specification is no better than the others. There spec sheets states CEP50, which basically means 50% of the time you will be within the stated accuracy. No one in the GPS world really works on 50%, they typically look at 95% with a stated accuracy of typically 10 metres for a GPS engine. In any event I do see no obvious differences between them all, however, I do want to know what GPS engines are in all of them. Why? Well, even though you only need 3 satellites to get a position (4 if you want height as well) the older engines may have issues with various extreme environmental conditions such as satellite signal scatter, location in a canyon, in forested areas etc. I do not know which 16 channel engine GME are using but I suspect it is either a Nemerix or the Starfire from Navcom (John Deere company). Either way, they will have better specs than any 12 channel GPS engine typically in the vicinity of 25db which is a lot in real life terms. So, based on what I know the following data is prioritised correctly. The locating accuracy is limited by COSPAS-SARSAT system because they have not kept up with the times and maintain a GPS location accuracy within 124 metres (4 seconds of arc). Anything below 124 metres is a furphy.
KTi up to 1 metre* (16 channel GPS engine StarFire III) suspect same as all others of around 100 to 150m.
GME <100m (16 channel GPS engine)
Kannad <120m (12 Channel)
ACR <100m (12 Channel)
Pains Wessex <150m (12 Channel)
*Detection accuracy (CEP50).
The next issue is strobe, I love strobes because even though the unit may or may not have a GPS a strobe is an added cost effective feature that I can't go without. It is certainly mandatory with the none GPS unit but even so at night time with a 150 metre radius (GPS version) a chopper with a spotlight searching in rough seas at night still may struggle to locate you. A nice bright little strobe light blinking every 3 seconds is worth the extra few dollars.
KTi both units have a strobe plus signalling mirror & retro reflector
GME both units have a strobe but no mirror/reflector
Kannad No strobe/mirror/reflector
ACR No strobe/mirror/reflector
Pains Wessex no strobe/mirror/reflector
User replaceable battery is a nice feature, however, not allowed in Australia. Only one of the manufacturers (Pains Wessex) quotes this but is quoted on the UK web site. Personally to me it's like packing your own parachute for the first time :eek
I don't know about you but one day of battery usage? Even though the Search & Rescue mob can take off from the base and pick you up within 24 hours, as KTi said, what happens if you are in the middle of a cyclone? Somehow my instincts tell me I won't be seeing that chopper for quite a while. As with the Kannad your battery will only last 24 hours or so, but you may have drifted well and truly away from the last reported signal.
Usage time is as follows:
KTi 4 days
GME 2 days
Pains Wessex 2 days
ACR min 1 day +
Kannad 1 day +
Size may not matter, depending upon where you have to put it. Clearly the KTi will best fit my pocket!
KTi: 125mm x 84mm x 35mm
GME: 135mm x 71mm x 38mm
Kannad: 132mm x 88mm x 45mm
ACR: 149mm x 56mm x 36mm
Pains Wessex : 146mm x 79mm x 54mm
price is to me last on the list but Pains Wesse x did say their unit is to military specification MIL-STD-810
What the spec means is it is going to cost the manufacturer and thus the end user a lot more money for the privilege of having that MIL -spec on your product. Not to say it is an over the top requirement but certainly pushes the product above the others especially in price.
Following prices are RRP and for the GPS kitted version.
Pains Wessex $1,099
GME Electrophone $175
KTI EPIRB $140 approx PLB $100 approx
ACR EPIRB $370 approx SART $236 PLB no price as yet
Pains Wessex Free replacement after 5 before 10 years, after 10 years no price as yet.
Well, sad fact of the matter is, although to me the KTi Mini-Sat-G 406Mhz PLB stands out against all others the model is not available until around August 2008 (pushed back to Jan 2010). So, if you need a unit between then and now quite clearly the GME Electrophone MT410G is the next in line.
What surprises me is the Kannad is dearer than either of the Australian products but is inferior to them as well. The 24 hour + battery life is a stinker and I would not even consider it a worthwhile investment on my life. Kannad is now distributed by Next Destination, the current Magellan Distributor for Australia.
Just a note, you must register the 406 MHz beacons as they are programmed with a unique identifying code which is transmitted by the beacon in an emergency. If you don't you can get fined.
After you purchase a 406 MHz beacon you MUST register this unique code with your local rescue co-ordination authority (see below for details) so that, if an emergency occurs and you need to activate your beacon, the authorities will have immediate access to your name, your emergency contacts and the type of vessel or craft you are in.
You may be keen to buy from USA etc but be aware, AMSA in their great wisdom decided to add an additional code to the beacon transmission making the PLB in Australia unique to the extent they will know if the item is an import. Personally it infuriates me when the various government agencies think we need to be different to the rest of the world and thus what is good enough for USA or Europe is not good enough for us. It is just a means to keep the in-efficient red tape happening and keep jobs. :angry2 Let me tell you about "Intrisically Safe" products.....

KTi Mini-Sat-G 406Mhz PLB
Any news yet on when the KTi Mini-Sat-G 406Mhz PLB will be available and what the expected price will be?
KTi still unavailable - just bought GME 410G
I am organising for a trip to the remote Diamantina NP and other less remote NP's in SW Queensland in June and needed a PLB (along with other items including a UHF radio). After reading Niko's excellent review I decided on the KTi (with GPS) as first preference & GME 410G as second preference.
The GME 410G units have been out of stock at any places in Brisbane quoting less than "extortionate" prices. The KTi units are STILL shown on the KTi website as "awaiting COSPAS SARSAT approval" and no indication as to when they will become available. So, I decided to order the GME410G from Whitworths Marine & Leisure who offered the best price in Brisbane - $599 and I picked it up today - they appear to have a few in stock now. I did check Niko's on-line shop but could not see any unit listed.
I did consider the SPOT device but decided against it on two points - It is not really up to the standard required for "Absolutely must work" in an emergency situation and another review I found indicated that the GPS receiver in this unit was fairly low sensitivity and appeared to be much like the "old technology" GPS units that would not work in heavy tree cover.
I hope these comments will help other forum members
McMurdo Fast Find Personal Locator Beacon
This PLB is also available in Australia.
The web site is
You can read a review at:
My issue is how it can retail in the USA for about $350 aussie
but becomes $699 by the time it lands here in Australia.
I'm not quite sure why the price doubles...
plb purchased from overseas
I guess my question is will it work here rather then registration process, i guess most of them advertise that they work anywhere in the world. For example last week i was sailing in malaysia with my brother and then the week before that walking in switzerland in the mountains. so obviously one can't have it registered everywhere. But i want it "mostly" for hiking in australiain the mountains. but it seems that the cost of some of them are about double their aussie price in the us It seems we are being overcharged
purchasing a plb overseas
thanks for that so it seems that they will work anywhere in the world
plb buying here or overseas
i have ordered the gme from whitworths, they seem to be the cheapest, $629 + postage. my local camping world wanted $900 odd for it so I could not buy it off them, i decided it was worth supporting the australian made brand with registration here. kti have not been able to produce one or give a reliable date of delivery. the fast find which may be a better model is available from the usa for $us299.00 which is pretty tempting with the aussie so high
thanks for your help
