and I have all sorts of things to help. I have both the 10.5" and 5" coils, with their own lower- and middle-stem extensions, so changing coils only takes a couple minutes. Nail aprons are good for keeping junk and good targets separate. I use a Lesche digger, and a Vibraprobe 460, both of which are mounted onto a military web-belt, along with the hipmount bag for my CZ. I keep a kitchen towel tucked into the web-belt to scoop loose dirt onto (I need to replace this one, it's getting tattered). In the goodies pouch of my nail apron, I have a small nylon-bristled brush for brushing dirt off of copper coins and odd-ball objects (silver doesn't get brushed), and a small pair of handheld pruners for small roots. I use a pair of rubber-coated gardening gloves to protect my hands while digging. I wear a pair of kneepads to protect my knees. That's just what I carry ON me (except the optional coils) when I'm in the field.
In my vehicle, are the extra coils, a small shovel, a tool kit with small ziplock baggies (to keep finds from different areas separate), extra batteries, spare o-rings for my CZ-20, Vaseline, a keyhole saw (for bigger roots), and some spare nylon bolts and wingnuts for my coils. I've been known to carry a sifter, PVC buckets (for trash or dirt when sifting), etc. Since it's almost summer, I'm also carrying my CZ-20 right now, along with my water scoop. Some folks have enough gear to fill the back of a truck.
On the flip side, the minimum of required equipment is a metal detector, and a recovery tool, usually a screwdriver. It just depends on how much stuff you want.
