For a quick few seconds after reading the start of this post I thought to myself "why did I buy a detector with TID info". But then I realized for the most part, I'm very sure of what I'm digging when I compare the pitch of the tone, intensity of the tone, size of the object I'm swiping over along with the target id.
You really have to get used to comparing all of the information that you see and hear while detecting to get proficient with the 705 or for that matter, any detector. If you are not taking the time to remember what you dig when you have taken all of that data into consideration then you'll never get good with the 705. I admit that from time to time I'm surprised when I've dug something that didn't jive based on the data that I've heard and seen while I'm swiping over an object but for the most part the 705 becomes like a magnifying glass once you get a few years behind you.
I think the biggest problem that people have is that they don't take the time to remember what they've heard and seen on previous targets. I really think that is the hidden secret to effective detecting. It's fun to be able to say "zinc penny", "copper penny", "silver dime" and that's what you pull up. It would be nice if the target Id was the only thing you needed to know to determine that but you have to take the sounds into consideration with the id. If any of you haven't already, take off the training wheels and get into 99 tone mode. It'a s little confusing and overwhelming at first but you'll get used to it. And yes, I know that there are not really 99 tones.
Have fun!!
