Hmm
Terry, I am not sure why you say an EPIRB is better than a PLB for land use.
There are a number of reasons that they are better for marine use. ( floats upright, registered to a vessel not a person so you can change crews, automatic activation when immersed in
water or the vessel sinks , 2 day lifetime when activated etc).
However while they will work for land use, they are actually not recommended.
Their large size means they may be stored at a hard to get location ( a PLB can and should be accessible to anyone in a vehicle in the event of a major accident) and they are not something you could take with for a walk or to get help.
But the biggest issue is that they need the antenna to be vertical to work properly and they actually use the
water as a ground plane to reflect the signal upwards.. They are specifically designed to float this way, but are not designed to be stable this way on land due to the shape.
If you're in a car accident, you may not even get a choice to align the antenna vertically, even if you could find where you packed it.
PLB's have a different antenna system. They can work with the antenna in any direction, though vertical is still optimal. Set it off and you are away.
For occasional boat hire, surely a PLB would suffice if you are less than 2
miles from shore. If more than that, the boat should have an EPIRB by law anyway.
I am curious what makes you believe they are far superior for land use. Would you be kind enough to elaborate. I must be missing something.
