The Rat phones are very good and the best that I have used. With the Filter installed for Minelab you get allot more Volume out of them and a very different sound that takes some getting used to, but really helps with the deep ones. We have tried them with a Garret Ace 250 and with the Filter on it was Awesome to say the least, The Volume increase and tone was impressive and very loud. My last outing in Sedial Mo. I was very blessed to get to hunt some Virgin yards that produced allot of Old Nickels,and Silver Quarters that I hardly ever find any more. Testing with the filter I would of not dug the Nickels, but with the Filter on it made
all the difference, they were deep and the soil was Sandy.
