This is what I carry in what I call my "gut bag":
Wyoming Knife,
trail marking tissue- orange,
Plastic gloves,
Singles edged razor blades - I use them to trim the breast fur before I cut,
small zip ties to tie off for rectum and attaching tags,
Leatherman tool with saw to cut the breast bone,
Plastic bag for liver and heart,
Deer drag - old seat belt strap w/ loops on each end - 6-7 foot long,
A couple hand wipes,
Small compass - usually around my neck
All this goes in a small pouch that goes on my belt. Should I get a hit it's all I need to and start tracking.I usually leave all else (except my bow) at my stand location when i start out to track
