Inova X5 with threaded tail:

1/4"X20 tapped hole in tail of light

Loc-Line stalk attached to light via 1/4" screw in first segment

Other end of stalk attached to magnetic base (seen below)

Cetacea mini web coil camera tether attached to light

In addition to making a good neck strap or tether, by double looping, tether makes a

useful wrist lanyard. Light can be let go when hand is need for other task.

Tether may be quickly secured and removed from light by screwing or unscrewing swivel

respectively. Stainless steel ball bearings in nickel plated brass swivel reduce torque

friction to a level well below that required to overcome compression of O-ring and cause

swivel from unscrewing accidentally.
