What ecriscit said. Fisher F2 is a well respected performer, $200. $215 with an extra small coil (worth it.) This treasure commander is a largely unknown detector. Spend the extra.
For very cheap entry level, look at Harbor Freight 9 function MD (use 20% off coupon), or Bounty Hunter IV at Hobby Lobby/Michaels? (use 40% off coupon.) Both decent for your money in my opinion. Get hooked then you end up buying the Fisher anyway like me.
