Round the bend in a line
A straight probe reaches the junction and stops being useful. Steering the head is what lets you look up the branch instead of at it.
3.9 / 6.2 / 8.5 mm · 180° each way · 1 m probe
A 2 MP camera on the end of a 1 m semi-rigid probe, with a roller on the handle that steers the head 180° to the left and 180° to the right. Your phone clips to the handle and does the looking. Pick the probe by the opening you have to get it through.
All three are the same handle, the same roller and the same 1 m probe. The diameter of the head is the only figure the maker changes between them.
Steer the head, not the whole probe
Roll the wheel under your thumb and the head turns — 180° one way, 180° the other. That is the difference between seeing the end of a bore and seeing the wall of it, the far side of a weld, or round the bend in a trap.

The head
The camera sits behind a stack of glass at the very tip, with the LEDs around it, so whatever you are looking at is lit from the same place you are looking from and does not throw its shadow back at you. Brightness is set on the handle rather than in the app — there is a second button beside the shutter for it.
Lit from the lens, which is the only place a light helps inside a bore. Brightness steps up and down from the handle.
Nearer than 2 cm or further than 10 cm and it softens. That is a short working range, and it is normal for this kind of camera.
The maker rates the probe for standing water in a trap or a part-flooded bore. The handle is not rated, and neither is the phone clamped to it.
One number the maker gives twice, differently: its lead photograph says 1080p, its spec sheet says 1920 x 1440 for both stills and video. Both are printed below rather than whichever reads better.

* Nothing here is measured by us. Where the manufacturer publishes no figure, there is no figure.
One sheet covers all three sizes. The head diameter is the only line on it that changes.
All three come from the same listing. We cannot make them agree, so here is what each source says and what we are prepared to promise.
Where it goes
The manufacturer sells it for pipework, engines, ducting and drains. These are its photographs.

A straight probe reaches the junction and stops being useful. Steering the head is what lets you look up the branch instead of at it.

The head and probe are rated IP67, so a full trap or a part-flooded bore is what they are for. Keep the handle out of it.

Pipework, under the hood, air-conditioning ducting and blocked drains. Anywhere you would otherwise be working off a mirror and a flashlight.
Using it
Nothing to pair and nothing to charge: the maker lists no battery and ships no charger, so the phone carries it.

The handle ends in a cable. On a USB-C phone it goes straight in. Read the connection note under the specifications before you count on Lightning.
The maker does not name one anywhere — not in the listing, the spec sheet or the photographs. If that matters to you, ask us before you order rather than after.
Push the probe with one hand and roll the wheel with your thumb. The roller is damped, so the head stays where you leave it while you are reading the screen.
Two directions, not four. The head bends in one plane; to see the other walls of a bore you turn the whole handle in your hand. A scope that bends up, down, left and right on its own is a different tool at a different price.
Three sizes
One spec sheet covers all three. The head diameter is the only line on it that changes.

If the optics differ between the three, the manufacturer does not say so. We have not taken one apart to find out.

180° each way · 1 m probe · 2 MP
Pick the probe by the opening you have to get through. The 8.5 mm is the cheapest and the easiest to feed; the 3.9 mm goes where the other two will not.
