Tom,
I’d vote for the DeLorme unit, for a couple reasons.
First, tracking function can seriously narrow a search window.
Second, you can share the tracking map with whomever you choose, as opposed to the PLB alert which goes only to RCC. You can, in fact share that link with Flight Service, for reference in the event you’re overdue on a flight plan.
Third, the DeLorme offers alerting capabilities over and above what a PLB does. Suppose you have a flat tire at some remote strip....no cell service. Not an “emergency”, but you need help. The DeLorme can reach different places that you select and program, like a flying buddy.
Fourth, the DeLorme will send messages...to someone other than RCC.
Finally, I sincerely hope that you have a 406 MHz ELT installed in your plane. If so, you already have that function covered.
As to flares, in my opinion, they are virtually useless in daylight, and only marginally better at night. I carry long duration signals, NOT short duration ones. I’ve been damn near shot down by a flare before I saw it during a search (daylight).
Think flashlight....LED with spare batteries for night, and maybe a pen laser pointer. For daylight, deplorable panels, space blankets, Mylar, etc. a roll of the yellow “caution tape” you see everywhere.....decorate a tree, shrub, or string it all over a meadow.
Smoke canisters.....there are small ones...are short term, but last longer than flares.
Use your imagination, there are lots of every day things that work as long term signals.
Flares have expiry dates, and yes, some states consider them firearms. Don’t even think about showing up at TSA with one, and I’m not sure postal service will take them. Going to Canada? Better check, and don’t forget....
