I want this too. I want to be able to record date and time and location and the weather and temps and which way the wind was blowing and what the relative humidity was, and what the soil moisture content and soil temperatures were, and the elevation of the site above sea level, and whom happened to be hunting with me that day, and what they in fact found that trip, and the depth and description and condition of the find(s), and the exact GPS location of the finds, and what mood I was in, and if there were any butterflies or other fauna skittering about, and if it was forested, or clean lawn, or saltwater or fresh water, and the hottness of the particular soil. But then I want to expand and categorize the trips by most to least productive, and be able to do searches on the number of trash finds made, including, but not limited to rusty steel bottle caps or newer not so rusty bottle caps, and pull tabs, and the type and style of pull tabs and foil wads and twisted ragged can slaw finds and nails, big, small, rusty, straight, bent. Not to mention the model of machine used, and the coil used, and the settings of the particular machine used when finding the find, such as sensitivity and scrim and whether or not I was close to neutral gb. Also, a rating for trashyness of the site from 1 to 10, 1 being totally clean, and ten being a public park. But, it would also be nice to record the presence of stranger enemy tectorist dude(s), if encountered, including anecdotal info of the killer finds they told you that they had made years ago at the particular site. And what the names and addresses and phone numbers are of new leads. That's just a start.
