Interesting article. However the writers of the article sells rather expensive Pulse induction machine. Almost 4 times the cost of a two box. I have no idea on how their PI machine works as I have never used that companies product
I have seen one review of the TF900 on line. It was a pretty positive one. You can find it on google. I have also talked to the owners of a few TF900 users. They seem happy.
From what I understand there is some difference between the TF900 on the White's TM808. What the difference is I have no clue.
I am going to get a TF900 myself. Seems more usable than my old Gemmini 3.
I have heard more positive feedback on the Discovery unit as opposed to the White's machine.
How big is your target? There are other two boxes out there and other options as far a detectors.
