I work midnights, get off at 8am. I am a police officer and my wife stays at home. So I am able to hunt any morning on way home from work. As far as tips...sure..
First stamina...are you physically able to hunt 3-4 hours minimum? I do not plan a hunt shorter then 3 hours...if I do it is only because daughter is at dentist or something like that...
two- location do you live in a heavily populated area? I live in a city of 2 million, like to hunt on my own and rarely stop to chat...unless approached then I am polite..
Three- do you have a lot of parks unlimited? If you do they should not and could not be drying up...unless heavily hunted by others...I do have a few parks that are regularly hunted by others...no insult but most seem unable to hunt anywhere but the woodchips...and then maybe an hour..which again goes back to how long you can or have time to hunt. Finding a lot of coins is a challenge...
Four- do you ever have a good day? If you don't sorry to say maybe it is you or a defective detector....
five do you have a quality detector? Do you know how to use it? I see to many people asking questions that are clearly defined in the owners manual...
As far as individual tips...speedy recovery with accurate pinpointing...
I try not to kneel down on ground..I bend and stay on feet...requires a good set of knees.
Do not sit trying to figure out if a coin is a great find or not...plenty of time to look at home...move on..
I am more comfortable hunting with less people around...but in my area does not take long for parks to get highly active...point get used to hunting around people...
Hunt where people gather...sit..bleachers...sidelines...so on..
None of this is rocket science...I know most know this already..
I would say the two main things are location and ability and knowledge to complete whatever you are doing or hunting for..
