Coin test garden prep

Here are some tips I've gathered (and mostly tested) that will help you build a good test garden for your detectors.  Some of these I came up with myself, others were gathered from detecting sites... I'm sure I'm forgetting a few things, but this will help you get started if you want to have a good test garden!
  • Sweep your prospective spot while in all metal (no disc) to make sure there is NO iron present.  Remove any that is present...if it's flakes, find another spot
  • Chart where you bury stuff with a map! (yep..unless you're super human, you'll forget years down the road)
  • When digging your hole for placing the test objects, check them CAREFULLY with a pinpointer to be sure there's no other metal present.
  • When you place your test objects, pour a little salt water on the object while it's in the the soil, prior to reburying.  This will speed up the effect normally seen when objects have been buried a long time.  Caution...the test won't be legit until the salt water dissipates after a few days.
  • Bury coins and objects at different angles if possible so you can learn how they sound
  • Bury some nuisance items as well, beaver tails, pull tabs, foil, etc.
  • Golf tees pressed to almost flush with the ground, or gold ball markers can make good visual indicators of where you have things buried.
  • ...MOLES!  Yep...they will change things! (air space between the coil and the target)
  • Test your garden on dry days and wet, wet days to see the difference in signals
  • Bury some coins adjacent to common iron objects (square nails, for example)  This is a great way to test target separation and detector reset speeds
  • Just for the heck of it, bury a coin TOUCHING an old iron object (like a nail)...interesting, huh?
  • When you REALLY want to go crazy, bring in some different soil types and fill in a 2 foot x 2 foot, iron rich clay has a very humbling effect!
  • Be sure to bury a few coins that are barely TOO deep.  You may eventually find a detector that will sniff them out!
