Guest Posted January 25, 2013 Share Posted January 25, 2013 Been reading both Australia Marine advice about these devices. Australia advice seems more precise than Maritime N.Z and is at complete odds with Maritime N.Z. Compare GPS versus Non-GPS http://beacons.amsa.gov.au/gps.html http://beacons.amsa.gov.au/activation.html N.Z. http://www.beacons.org.nz/Sea.htm Australia states most plb's that have floatation capabilities do float, but not upright as they need to be, to work accurately. N.z. does not state this just states they float. Discrepancy in distances the epribs pin point spot. Australia seems to be correct. Link to post Share on other sites
Guest Posted January 25, 2013 Share Posted January 25, 2013 The "Voyage to the bottom of the sea" PING.. Ping.. ping.. is a bit stupid!!! (http://www.beacons.org.nz/Sea.htm) other than that, what's the prob? GPS equipped EPIRBs supply a fix, others don't... not straight away.. and even then, ify!! Link to post Share on other sites
mountie 0 Posted January 25, 2013 Share Posted January 25, 2013 My understanding is that the ARIEL needs to be upright. Some PLBs come with a flotation pouch, which is intended to orientate the beacon's ariel as above. Dedicated marine EPIRBS are designed to float upright, with the ariel vertical. My thoughts on GPS equipped vs non-GPS equipped, are that non-GPS equipped should not be manufactured. Link to post Share on other sites
curt 1 Posted January 27, 2013 Share Posted January 27, 2013 gps epirbs win. they also transmit still on 121.5 for local aircraft to hone in on I understand, which is a big thing when you in the bush or rough sea! GPS EPIRBS only need one pass to get a fix away and boom, your location is known to 10m. Link to post Share on other sites
Steve Pope 243 Posted January 27, 2013 Share Posted January 27, 2013 All 406 epirbs still transmit on 121.5 to allow the search aircraft to accurately locate the vessel / plane once the 406 has got them into the vicinity. Link to post Share on other sites
Guest Posted January 28, 2013 Share Posted January 28, 2013 Lots of yes and nos here. PLBs Both OZ and NZ require both PLBs and EPIRBs to float. This compares with other countries which don't necessarily require PLBs to float. This is why you see the McMurdo Mini so cheap overseas as it doesn't require the neoprene pouch which is added to be legal here. Some older models of PLB did float with the aerial pointing upright but are no longer available. In addition they were much more expensive and therefore less popular. We don't offer PLBs without GPS. EPIRB While GPS is advisable, it isn't essential for ocean cruisers. If you are in the middle of the ocean, an Orion will home in on the 121.5. However for Coastal use, the GPS makes a lot of sense.
