You do not need unlimited tracking. The basic tracking is all you need and much preferred.
SPOT is upgrading their infrastructure during our event and there could be some hits. They say that tracking, OK, Custom, Help, and SOS will work but some short delays might be encountered. Many thanks to Etchemin for this heads up. Here is a link to their info: Spot Upgrade Info
I am working with RaceOwl to have them track our events. WaterTribe will continue to track the events as well. Many thanks to BustedRudder for the reference. It isn't finalized yet, but as soon as it is there will be a link on our Tracking Map to the RaceOwl site. Of course you should always give your family and friends your SPOT shared link too.
The SPOT is not a waste or superfluous. First, over the years we have had many SPOTs become dysfunctional during these events. Mostly this was due to water intrusion, but other stuff happened too. I do think the latest version is better, but it still bugs me. The typical PLB on the other hand is much more robust.
The primary purpose of the SPOT is to track these events. Ask any of our Race Managers or CP Captains and they will tell you how important it is. It also serves as a backup for the PLB. I'll say it again.
Two is one and one is none.
And finally, you should be using your SPOT and carrying your PLB every single time you go out for an adventure. If you don't, well then I guess it is a waste.
Of course, I might be a bit touchy right now. It's these drums I keep hearing in my head.
