Buyers Tips: Personal Locator Beacon's (PLB)

Beside boots,  a Personal Locator Beacon (PLB) will probably be one of the most expensive pieces of kit in any trampers arsenal. I recently brought a PLB, so here are a few tips I discovered while researching my purchase.

What is a PLB?

Also known as a Rescue Beacon, a EPIRB or Safety Beacon. In basic terms, a Personal Locator Beacon (or PLB) is an electronic safety device that when activated sends a distress signal to a satellite. The satellite system informs the rescue authorities in your location, a Search and Rescue operation is then initiated.

Please note: Only 406Mhz beacons are monitored in New Zealand, please check if your PLB will work here if visiting from another country.

Why buy a PLB?

What a personal locator beacon offers is a measure of security. If you or a member of your party has an accident which precludes walking then this is your quickest means of summoning assistance. Why wait for days when using your PLB could mean assistance within hours.
PLB's are useful for all outdoors folk but should probably be required equipment for solo trampers.

Where should I buy?

Most PLB buyers will purchase their beacon from a local hunting, boating or outdoor shop. It is probably preferable to buy local as warranties and servicing will be easier to obtain.
There are also a number of online New Zealand based suppliers, Aviation Safety Supplies Ltd is the most well known. You can buy your beacon online overseas but be aware that they will need to be re programmed to work in this country, this costs approximately $120.

Common brands and prices

There are numerous brands and types of beacon's available, i will discuss four of the most common brands I have encountered while tramping:

ACR ResQLink

ACR ResQLink PLB
 

One of the larger manufacturers is ACR. The company produces a number of beacons, the more expensive are GPS capable.
GPS capability means that the potential search radius is much smaller, they are accurate to 30 meters. Non GPS equipped beacons have a 100 meters radius by comparison.
Standard pricing ranges from $500-$700 depending on the supplier.

The ACR ResQLink is the beacon used by the Southland Locator Beacon Charity.


Fast Find McMurdo

McMurdo Fast Find 220 PLB

Another brand is the McMurdo 220, they are smaller than the ACR beacons and have very similar features. These beacons float which is an important factor to consider when using it in the New Zealand backcountry. I have been told it is slightly more difficult to extend the antenna on these, but have not tried myself.
Again, these range in price from $530-$700 depending on where you purchase the unit.

AccuSat GME MT410G

GME MT410G PLB


I have seen a couple of people with AccuSat GME beacons, cost is around $500 from Aviation Safety Supplies. They have a hard protective outer casing on them, an excellent feature as PLB's tend to get knocked around. Because of this they are slightly heavier than the ACR and McMurdo Beacons.
I believe they are aimed at the boating community more than trampers.
 
Here is some info from their site:
 
The MT410 and MT410g provide the aviator and or the outdoor adventurer with a 406 MHz PLB that is not only affordable, but provides enhanced peace of mind for boaters, bush walkers, 4 x 4 enthusiasts and aviators should they ever require emergency assistance.


SPOT Find Me

SPOT Find Me PLB


You can buy a Spot Find Me for about $300, and they are the smallest and lightest of the four. They have excellent tracking functions and allow for pre programmed messages to be sent.  One negative feature is a US  $150 per annum fee to register it...so you would be looking at $1200 for the 6 year life of the unit.

My Beacon


I decided to buy a ACR ResQLink for three reasons:
 
Familiarity: I have hired these beacons before and found them light and easy to use.
  
Price: I brought mine for $530 from Hunting and Fishing (Ballingers) in Christchurch. This was the best price within New Zealand for a ResQLink PLB, the other suppliers were selling them for up to $630. This was also one of the lower PLB prices regardless of brand.
 
Functionality: These are the easiest to use of the three beacons: the antenna is easy to extend and requires minimal pressure to do so. The controls are obvious and really simple to use. One feature I really like are the instructions printed on the PLB itself.

Personally, I would recommend that every tramping party carry a PLB. The added layer of security they offer is certainly worth the price and weight.
