Just grabbed myself a T2 Ltd Edition. Well the boost works ! I used it on my Roman site trying the 2+ against it. a good amount of difference, some finds I would not have made on 2+ This one a Dupondi of Antoninius Pius reverse Liberalitas A.D. 138 /161 I had a fair signal with 2+ then checked with boost !! another 8 inches above the ground.The day before on 2+ I found this 4th Century Turret ring very small
