To my knowledge there is no inline probe made for any Tesoro's, yet. I have the Sunray S-1 inline probe for the Sov GT and am lost without it as it is like a 1" coil. The various handheld ones are like toys.
I have had several in line probes. They are great, but they add weight to the detector . One of the main reasons I switched to Tesoro was their light weight I now own a Garrett hand held pro and for me there is no comparison . The Garrett is the best hands down.
As calbear said, the light weight is an advantage with Tesoro detectors. Though the inlines are handy, the Tejon was one detector I was able to use a variety of hand held pointers with little or no interference. This way I was able to go all day with little fatigue. But you never know, someone may come out with one.
