ACR ResQLink + PLB

So I do paddle solo on the ocean from time to time in remote areas and have been carrying an ACR AquaFix 406 EPIRB (center) for the last 5 years. Luckily have never had to use it. After 5 years you have to replace the batteries and found out it would be $250 to have the new battery installed so I bought an ACR ResQlink+ (2881) PLB (left) instead for the same price. About half the size and weight of my EPIRB and it has a built in strobe and it floats. Smaller than an Iphone 5 (right) as far as length and width but much thicker (1 ½”). Probably use it for hiking and skiing also.

PLB's are commonly used by sea kayakers in Australia and New Zealand and I believe they they are required on all vessels more than 2 miles offshore. In the U.S., they are less commonly used by kayakers. Now that they have come down in cost and size, hopefully more kayakers will use them. Here is an interesting discussion about PLB's and kayakers. http://theartofpaddling.com/2012/08/10/personal-locator-beacons-and-me/

As far as EPIRB vs PLB vs SPOT, here is a nice review:

I have been thinking of getting one but haven't decided.  Thanks for the review link.  It's informative.
