Thank you both for useful info's.
Considering possible purchase of my mentioned "very lite" version, I stated that
"LITE" combination of ORX/Deus 9x5" Elliptic HF and wireless earphone WS4
is not significantly cheaper than factory Lite ORX version - package consisting of:
- ORX 9x5" Elliptic HF coil
- lite collapsible shaft
- remote control and
- wired earphone.
Shaft will be here in most cases (for my way of detecting) a surplus. But Remote
control, which will be "front waist mount" (this way wired earphone do not disturb)
allowed software upgrade and more settings which is big Pro here.
Mentioned Remote version is available here in EU for 549 Euro and Ell HF coil +WS4
combination is not significantly cheaper.
So my current consideration go in direction of purchase lite version of ORX package.
Thanks again.
