When you inspect an engine bay, wall cavity, or pipe run with an articulating borescope, the first failure mode is usually not the tip — it is a loose phone mount that twists the moment the coil flexes. Here is the seating checklist I use before the tip goes into a dark cavity.
1. Lock the phone before you unlock the tip
Seat the phone fully in the cradle, then tug the cable once. If the phone pivots, reseat. A half-click mount will look fine on the bench and drift as soon as the coil loads.
2. Zero the articulation on a known surface
On a table edge, articulate left/right/up/down through the full travel. Confirm the on-screen orientation matches what your hand expects. Recalibrate or remount if left/right feel inverted.
3. Feed coil with slack, not tension
Push from behind the tip in short strokes. Keep a soft loop of slack so articulation does not yank the mount. If you feel sudden resistance, stop and reverse — do not force past a bend you cannot see.
4. Confirm lighting before deep travel
Check LED level on a mid-tone surface first. Too bright washes metal glare; too dim hides cracks. Adjust before you are 40 cm into a cavity.
5. Capture a landmark frame
Take one still of a known landmark (bolt head, joint, label) before you go deeper. It is your breadcrumb if the tip rotates mid-inspect.
