Here is what I found for the clips on the S1 probe. I cant get the picture on my phone to download or I would show you the picture . The one I do have is for the S1 probe on a Elite or GT shaft, these mount on the arm cuff instead of the shaft as you remove the 2 bolts that hold on the arm cuff and run the bolts through the bracket and back to the arm cuff. It has 2 clamps to hold the probe which might have been the earlier model as my GT has only 1 clamp to hold the S-1 probe.
On my Sovereign XS which I dont have anymore it had clip that snapped on the shaft and then the S1 probe would snap on to probe clip.
Never had a problem with the latter clip, but the first one always seem to beak.
I wonder if Ralph at Sunray still has some or know of some out there.
