antenna placement issues and practicality.

In a crash, an ELT might not activate, and even if it does, the antenna might be broken or below the wreckage. Or you might end up in a ravine and out of sight of satellites.

If you use a inReach or SPOT, then, using the basic tracking, you will leave a trail of "bread crumbs" collected every 10 minutes at the vendor's website. If you crash, then the last recorded position will be within 10 minutes of the crash site. If you're lucky, the device will survive the crash and pinpoint your location.

So, IMHO, this is a better solution to the hassle of dealing with an ELT.

I prefer inReach as it confirms your position update has been received. The SPOT transmits in the blind and there's a possibility your last (few) position report was not received.
