I am a newbie to the hobby. I purchased my 1st M.D.(Tek. Delta) about 2 months ago & still found it very unstable after a few good tips from the Teknetics forum on this website. By no means am I trying to knock it, I think its a good machine in certain situations & have decided to keep it. I decided to purchase another detector & give it try. After a little research & a deep discount, I decided on the BH Time Ranger & I cannot contain my joy after experiencing the results. Yesterday was my 1st day out with the TR with the 4" gold nugget coil installed. I decided to go back to the trashy area I hunted with the Tek. Delta & had problems. The TR was unbelievably stable & the 4" coil was awesome, I plucked 7 clad coins within a small diameter that I previously hunted with the TD & ended up with 10 mixed clad coins for the day. I am sure the TD I used earlier probably picked up the coins also but I was using the stock 8" coil & the readings were very unstable due to all the trash. I did notice on the TR that all of my finds were no deeper then 4-5" with the 4" coil, nevertheless it was a great day as a newbie for me! Thank you for the great products! Anyone with Time Ranger experience, please share some tips.
