Each area will have there own kit reccomendations.

The team I'm on has a "required" list

many teams though have just reccomended equipment. about a week or less ago someone on here posted a very very nice review of what was in their pack.

I keep 2 packs a Search Pack and a support pack

My Search pack weigh's in at about 20-25#. My search pack is loaded with the basics. Basic survival and first aid for both Victim and I. Along with Water and other important things.

My support pack has everything else. When I get on scene and can figure out exactly what is needed I move contents around and add or take things out of my Search pack. This way I can keep my pack light yet still have plenty of gear back at the base to use as needed. IE get back and I'm soaked I have dry cloths. One of these days I'll empty it all out and take some pictures.

Hope this helps
