A joystick lets one thumb steer the camera tip while the other hand feeds the cable, and on four-way models it also rotates and locks the head. This guide compares the joystick borescopes with the clearest manufacturer specifications, from a replaceable-tube industrial unit to a two-way automotive scope, and explains what the control type changes in practice.
Thumb Steers
Hand Feeds
Lock and Look
Every pick here is steered by a joystick. They were compared on four-way versus two-way control, stated rotation and flexion angles, angle lock, probe diameter and ingress rating, screen, battery and replaceable parts, using manufacturer listings and owner feedback. We did not run laboratory tests.

Control type and angles are as stated on each manufacturer's Amazon listing. The FOXWELL Y400 is included for comparison because it is often cross-shopped, but it uses a thumb wheel rather than a joystick. "Not stated" means the listing gives no figure.
The control system is only part of it; four points decide:
Four-way joysticks rotate and flex the head and usually lock it. Two-way joysticks sweep one plane; you twist the cable for the rest. Four-way is faster, two-way is slimmer.
A lock holds the tip while you study the screen or take a photo. It is stated on the N180 and the Ralcam 360; check the listing on others.
Articulation cables wear. A replaceable snake tube, as on the M5, turns a worn scope into a parts order rather than a new purchase.
Stated runtimes run from about 5 hours upward. A detachable battery and a 32 GB card keep a daily-use scope working through a shift.
Both steer the tip mechanically. A thumb wheel moves it in one plane, so it is always two-way. A joystick can do the same on a two-way scope, or on a four-way scope it moves the head in two planes and rotates it, which is why four-way models are almost always joystick controlled.
On the listings here it does: the Ralcam M5, Ralcam 360 and Mrcartool N180 all state four-way 360 degree steering. The N180 also states 210 degrees of flexion. Read both figures, because rotation tells you where the tip can point and flexion tells you how sharply it can bend.
The steering cables inside an articulating probe are the part that wears, and a crushed or bent tip can end the life of the whole scope. A modular tube, as Ralcam states for the M5, lets you fit a new or different-size probe to the same handle and screen.
Some can. The Mrcartool N180 states a phone data cable and Android app support, with iOS not currently available. The Ralcam M5 states file transfer to a computer. The Teslong 5.5 mm scope is designed to work without a phone or app. None of them require a phone to operate.
The M5 is the joystick borescope built to be serviced rather than replaced. Ralcam states a modular snake cable that swaps out for different sizes, which addresses the usual end of life for an articulating scope, a worn steering cable or damaged tip: replace the tube and the rest carries on. The joystick is stated as SUS304 stainless steel, chosen, per the listing, for frequent industrial use.
Steering is four-way 360 degree, described as smoother than the earlier Ralcam model, on a 6.2 mm IP67 probe with six LEDs plus one and three brightness levels. The 5-inch HD display, 4x digital zoom and 180 degree image flip cover the viewing side; a 5000 mAh detachable battery is rated for up to 5 hours, and a high-temperature warning triggers at 90 C. It supports a 32 GB card.
The listing omits camera resolution, the length of the supplied tube, and whether an angle lock is included. Owners of the earlier Ralcam 360 praise its lock, but it is not stated for the M5. It is the pick for a shop that uses a scope every day.
The N180 delivers the full four-way joystick experience at the mid-range tier, and unlike the M5 its listing states the angle lock outright: the probe bends, rotates and locks at any angle, which the manufacturer says removes the need to twist the cable by hand, with 360 degree rotation and 210 degree flexion on a 6.2 mm probe and a 4 ft semi-rigid cable.
The imaging specification is the most detailed here. Three capture modes run from 1280x720 to 2592x1944, the 5-inch IPS screen is 1080p with 8x zoom, and photos and video go to a built-in 32 GB card as JPG and AVI. The probe is IP67 and oil-resistant, six LEDs have four brightness levels, and a temperature sensor alarms above 85 C and pauses the image until the probe cools.
Two things to know: it carries two look-alike cables, silver for the handle and black for phone data, and swapping them gives no signal; and iOS app support is not currently available. Battery capacity is not stated. For an automotive shop that wants four-way steering without the M5 outlay, it is the buy.
Not every job needs four-way steering, and a two-way joystick scope is thinner and simpler. Teslong states a thumb-operated joystick that sweeps the tip through 180 degrees and holds any position, which is the part of joystick control that matters most: you can leave the camera looking at a valve seat while you study the screen.
The probe is 5.5 mm, the slimmest in this group, on a 5 ft cable, and the screen is a 5-inch 1280x720 IPS panel with 1.3x and 1.5x digital magnification. Six LEDs with brightness control, a 3000 mAh battery with USB-C charging, a hard case and an SD card complete the kit. It works without a phone, wireless or app.
The limits are inherent to two-way: the plane of articulation is changed by rotating the cable by hand, and there is no rotation or lock in the head. The listing does not state camera resolution or an ingress rating. For engine inspection through plug holes, where the slim probe matters more than extra axes, it is the sensible choice; see the engine borescope guide for that use.
Short answer: for a shop that will use the scope every day, the Ralcam M5 is the pick: a stainless steel joystick, four-way 360 degree steering, a 5000 mAh detachable battery and a snake tube you can replace when it wears. If you want four-way control with a stated angle lock and the best capture resolution at a mid-range tier, the Mrcartool N180 is the value four-way. If your work is engine inspection through spark plug holes, the two-way Teslong 5.5 mm joystick scope gives the slimmest probe and a 720p screen for less than either.
An articulating borescope steers its camera tip with cables inside the probe. How you drive those cables changes how the tool feels: a thumb wheel or slider moves the tip in one plane, while a joystick can move it in two planes and, on four-way models, rotate the head and lock it. The practical result is that a joystick scope is used one-handed. One thumb steers while the other hand feeds and rotates the cable, and on a four-way model the cable rarely needs rotating at all. Manufacturers make this point directly: Mrcartool describes the N180 as eliminating manual cable twisting, and the Ralcam listings describe the joystick as letting one person hold the monitor and control the cable. The general buying guide at how to choose a borescope for inspection work covers the rest of the specification.
Two of the three picks are four-way. The Ralcam M5 and Mrcartool N180 both state 360 degree steering, and the N180 adds 210 degrees of flexion and a lock at any angle. The Ralcam 360, the earlier model in the table, states the same four-way 360 steering with a lock. The Teslong 5.5 mm is two-way: its joystick sweeps 180 degrees in one plane and holds position, and the plane is changed by twisting the cable. Two-way is not a lesser tool for every job. It allows a thinner probe and fewer moving parts, and for looking at valves through a plug hole it is enough. Four-way earns its cost when you need to look around an object, such as a piston crown or a weld root, without disturbing the cable position.
Two features separate the industrial-grade joystick scopes from the rest. The first is an angle lock, which holds the tip where you put it so you can take a photo or study the image. Mrcartool and Ralcam state it on the N180 and the Ralcam 360; the M5 listing does not mention it, so ask before assuming. The second is a replaceable snake tube. Ralcam states for the M5 that the snake cable is modular and can be swapped for different sizes, which extends the life of the tool and lets one handle serve several probe diameters. No other scope on this page offers that, and it is the main reason the M5 leads the list.
All three four-way scopes here use a 6.2 mm probe, and the M5 and N180 state IP67. The Teslong two-way is 5.5 mm with no stated ingress rating. Lighting is six LEDs on the Teslong and N180 (four levels on the N180) and six plus one on the M5 with three levels. Heat protection is stated on both four-way picks: the N180 alarms above 85 C and pauses the image, the M5 warns at 90 C. The FOXWELL Y400, a thumb-wheel scope included in the table for comparison, shuts down at 70 C. None of these limits allows scoping a hot engine or a live exhaust, so let the work cool first. Where the job is temperature rather than appearance, thermal camera vs borescope explains why an imager is the better instrument.
The N180 has the most complete imaging specification: a 5-inch 1080p IPS screen, 8x zoom, and capture at 1280×720, 1920×1080 or 2592×1944 to a 32 GB card. The Teslong 5.5 mm states a 5-inch 1280×720 panel with 1.3x and 1.5x zoom and includes an SD card. The M5 states a 5-inch HD display, 4x zoom and 180 degree image flip, with support for a 32 GB card, but no camera resolution. On power, the M5 is the standout with a 5000 mAh detachable battery rated at up to 5 hours; the Teslong states 3000 mAh and a full shift; the N180 does not state capacity. For a shop tool that runs all day, a detachable battery is worth more than the extra pixels.
Daily industrial or fleet use, where the scope is a tool that must stay in service: the Ralcam M5, for the tube, the battery and the steel joystick. Automotive and general shop use, where four-way steering and a lock speed up multi-cylinder work: the Mrcartool N180. Engine inspection through plug holes on a budget, or a first articulating scope: the Teslong 5.5 mm two-way, which is compared against the other slim-probe options in the engine inspection borescope guide. If you are choosing between a borescope and a thermal camera for building or electrical work, what a borescope is and when it is useful draws the line, and the borescope section lists every guide in the cluster.
Borescopes were compared on manufacturer listings: control type, articulation axes and stated angles, angle lock, probe diameter and ingress rating, cable length, screen size and resolution, capture resolution, lighting, battery capacity and stated runtime, temperature protection and replaceable parts. Owner feedback was reviewed for joystick durability and steering cable wear. We did not run laboratory tests. Amazon data supplies images, availability and links only.
