What about 406?
I know both Spot and Spider well and your report in December's Aviation Consumer captures the essence of both of them. You also draw a sensible conclusion that they are apples and oranges and you get what you pay for.
But here's my beef with you on this. You parenthetically opened the question about whether 406 MHz ELTs are a worthy alternative or even an additional device intended to accomplish virtually the same task.
You hint that 406 is less than adequate in performance and you hint that sales of 406 ELTs have been weak. But this is not the Bertorelli who speaks straight talk and calls a spade a spade and provides solid facts and rationale for his conclusions and recommendations.
May I humbly suggest that you take on the obvious challenge to directly compare Spot/Spider with 4G6ELT? I have a hunch that you were simply teasing us as a precursor to an article next month that answers my question.
I see no significant incremental value in 406 so I will continue with my 121.5 MHz ELT, plus Spot or Spider. But the mandatory 406 requirements in Canada and Mexico place me in a jam because I fly across both borders.
In my view, Canada and Mexico have been duped into mandating 406 ELTs. Sure, they both have a grace period for U.S. aircraft, but that will soon end. If you believe in 406 ELTs, let's be reading your rationalel If I am missing something, I am all ears.
Paul Bertorelli concedes he is but a shell of his former self but promises to Lake your request under advisement.
