I would like to illustrate what to look for in a modern TM Wand,
regardless of which TM wand you use or buy . . .
The first attribute is the head design . . . It must flow a couple of hundred CFM's with modern TM's . . .
This requires a cast or milled head in most cases for smooth airflow . . .
Next, is the jet pattern when it hits the carpet . . .
I have posted two photos to illustrate the difference . . .
First is the 14" PC Titanium Wand with 6 jets . . .
and then the new DC ProTi with 4 modified jets . . .
Ideally, you want even spacing where the jets hit the carpet . .
Noticed the spacing as illustrated by the black arrows . . .
Top photo shows light coverage in the center, with much heavier spray under the #2 and #4 jets . . . .
------
Mikey did better with the new special order 4 Jet Ti wand . . . The center jets are ideal, but the outer two jets are too close to the wand edge . . .
Once the jets are close to ideal, we check them with a special tool to determine actual water distribution . . .
Jet angles also have an effect on impact, so 95 degree jets should outperform 110 degree jets for the same size opening . . .
Bottom wand also has no center spacer, since it is machined . . .
Of course, Jim & you raffle winners already know which assist handle is best . . .
