Field kits
The most useful target ID chart in the world is the one you make yourself, by burying known targets in your own soil at known depths and writing down what your own machine says. These are the sheets for doing that, plus the paperwork that keeps permissions: a settings card you fill in once and keep in the pouch, a permission letter template, a dig log and a grid search planner.
In preparation
Printable field sheets for the hobby: a blank target ID log, a per-machine settings card you fill in once and keep in the pouch, a site permission letter template, a dig log, a grid search planner and a pre-hunt checklist.
