1. PLB - that was an easy choice

2. This is actually a tough choice for me.

If I have the PLB, my primary objective is to be as "findable" as possible, so by day I would want a signal mirror, and by night I would want a bright light or a fire. I think I have a better chance of being seen by day without a signal mirror, but by night ... I'd say #2 Bright Flashlight. Under this scenario I'd say #3 is a bright (orange?) shelter material, as this would help me get found by day AND be a shelter against the wet & cold of night.

If I did not have the PLB, I feel like I should say the next item would be a knife, but the truth is that fire is so important for warmth, mental health, and signal that I think I'd have to say #1 Good Lighter or sparker & tinder, and then #2 Knife. #3 would be that bright shelter material I mentioned above.

I wish I could find a high quality bright orange poncho.

The rest of my necessity list would include a whistle, signal mirror, cordage
