Inexpensive Entry into Digital FPV
The Walksnail flagship goggles, the Goggles X, are priced at a steep $460. Whereas they’re the final word possibility relating to total efficiency for the Walksnail system, there are cheaper alternate options such because the Walksnail VRX. Nevertheless, it has a fancy setup with dangling cables and potential latency points could be deal breakers for some.
Enter the Walksnail Goggles L, a budget-friendly field goggle designed particularly for the Walksnail system, making digital FPV extra accessible than ever. Priced at simply $199, these goggles are a extra reasonably priced various to different digital FPV goggles in the marketplace.
In actual fact they’re fairly just like the Fatshark Recon HD that was launched a few years in the past when it comes to specs and options, however that was discontinued they usually had been barely costlier. It’s good that we have now extra low-cost walksnail choices.

Energy Necessities
Powering the Goggles L is versatile. The goggles settle for an influence enter starting from 2S to 6S, just like the costlier Goggles X. You may just about simply choose up any frequent drone batteries with XT60 connector to energy the goggle.
The entrance cowl has an LED panel that lights up when powered on. It serves as a very good reminder to unplug the battery and provides a technological contact to your gear. Nevertheless, it appears there’s no option to change the colour, however you’ll be able to flip it on and off within the menu settings.
Look, Consumer Interface and Controls
The Walksnail Goggles L characteristic a white plastic housing with a matte end and a well-organized format of buttons and connectors for ease of use.
On the precise facet of the goggles, you’ll discover a collection of important controls.
- From the left, there may be the 5D Joystick Button, which lets you scroll by means of the menu and ensure picks by toggling and urgent the button.
- Subsequent, you’ve the Again Button for returning to the earlier menu or exiting the present mode. Nevertheless, the Again button doesn’t appear to work in my unit. I can return within the menu utilizing the file button, and the Again button merely doesn’t do something in any respect. I hope it’s only a bizarre bug they will mounted in future firmware.
- Subsequent, is the Document Button, which is meant for use to start out or cease video recording.
- Lastly, we have now the Hyperlink Button on the far proper, which lets you pair the goggles to a VTX.
On the underside of the goggles, you’ve the three.5mm Port, offering head monitoring output. Adjoining to it’s the Energy Port (DC 5.5*2.1mm barrel connector), supporting a voltage vary of 6V–25.2V (2S to 6S).
On the highest facet of the goggles, there’s a Warmth Dissipation Outlet for sustaining optimum working temperature.
The Micro SD Card Slot is conveniently positioned above the show space beneath the faceplate foam, permitting quick access for storing and retrieving recordings. With a built-in Micro SD card slot, customers can simply file their flights.
For some cause they haven’t put any LED indicator on this goggles, so you must depend on its beeper to guess what state the goggles are in.
Lastly, there’s no USB-C port, so improve is completed by way of the SD card, and energy solely by means of the barrel to XT60 connector. There’s no video output to exterior show both.
Display screen and Menu
The 1080p screens look crisp and clear, offering excessive decision. That is ample because the Walksnail system helps as much as 1080p, and most customers favor 720p for higher stability and decrease latency. The interface and menu are an identical to what you see within the Goggles X.
Antenna Efficiency
One cause the Goggles L look so streamlined and clear is because of the built-in antennas. These patch antennas present balanced efficiency between protection and vary. Whereas particular beam width shouldn’t be offered, the acquire is about 4.9dBi, and the antennas are LHCP.
These are directional antennas, providing higher vary when flying in entrance of your self however doubtlessly decreased efficiency when flying behind. You may’t swap to aftermarket antennas, so these goggles should not designed for long-range flights or conditions requiring excessive penetration efficiency. They’re extra appropriate for indoor whoop flying or flying in small native parks.
Head Tracker Assist
Most individuals in all probability received’t care about head monitoring, however should you do, the Goggles L is for you. The pinnacle monitoring sensor, which makes use of a 9-axis gyro module, is built-in into the goggles to seize the pilot’s head actions. Paired with a gimbal, it sends alerts by way of the picture transmission system to regulate the digicam’s pan and tilt, offering pilots with a cockpit-like sensation. Caddx not too long ago launched some gimbals for this characteristic: https://oscarliang.com/product-e5un
It additionally helps PPM sign output to Radio Controllers by way of the Goggles L’s 3.5mm headphone TX connector, which in flip outputs to the drone.
Consolation and Match
Walksnail excels in creating goggles that match nicely, and the Goggles L isn’t any exception.Using thick, good high quality polyurethane foam, the goggles’ face masks ensures softness and luxury whereas decreasing gentle leakage for an enhanced sporting expertise. The froth is hooked up by velcro and is detachable.
The goggles weigh solely 351 grams and are comparatively snug, though some gentle leakage across the nostril space is frequent with field goggles. The offered foam padding is sufficient, however hopefully, we’ll see another aftermarket foam and headstrap choices for these in search of a greater match.
One difficulty is that the highest of the goggles will get fairly scorching after working for about 10 minutes, even when not paired with the VTX. Heat air will get blown to your brow and eyes, which could change into uncomfortable in scorching summer season days.
Lack of Low Latency Mode
The Walksnail Goggles L come outfitted with 1080p decision screens working at 60fps. This implies you received’t be capable of use the 100fps low latency mode accessible on the Goggles X, leading to about 35 to 40ms latency versus the 25 to 30ms latency of the 100fps mode.
Not for Individuals Carrying Glasses
The Goggles L makes use of a magnifying lens system, making the display seem additional away than it truly is, which helps scale back eye pressure. This setup is helpful for many customers, although these with important imaginative and prescient correction wants would possibly discover it difficult with out customizable diopters. There’s no focus adjustment, and the goggles are too small to suit a pair of glasses whereas sporting them.
In keeping with my contact at Walksnail, they will customise lenses for customers, however they require a prescription. The customized lens is removable, permitting for the set up of nearsighted, farsighted, or blue light-blocking lenses to fulfill particular person preferences. They’ll’t present me with a price at the moment so it’s unclear how a lot they are going to cost.
I want they might present generic lenses with -2, -4, -6 diopters like Fatshark did, nevertheless after discussing with Walksnail they don’t appear too eager on doing that and insisted on a prescription.
For individuals who put on glasses, the Goggles X may be a extra handy possibility as you’ll be able to modify focus contained in the goggles.
Compatibility
The Goggles L is appropriate with all present Walksnail VTX fashions – VTX V1/V2, 1S Lite, Moonlight, and so on. Nevertheless, the Goggles L is strictly designed for the Walksnail FPV System. As a result of lack of AV enter and HDMI enter, you received’t be capable of use the Goggles L with Analog and HDZero.
Goggles X Comparability
Regardless of the fully totally different design, the load and measurement variations between the Goggles X and Goggles L are literally extra comparable than I anticipated. With out battery, the Goggles X weighs 317g, whereas the Goggles L weighs 351g.
To judge the efficiency, I in contrast the Goggles L to my Walksnail Goggles X outfitted with unique antennas. Regardless of the Goggles L’s decrease body fee, the efficiency was spectacular. The sign power and latency had been comparable when flying inside 300m. In some circumstances, the Goggles L maintained even higher bitrate (Mbps) and latency efficiency than the Goggles X setup, in all probability because of the increased acquire antennas.
Buzzer Standing
The Goggles L doesn’t have any LED for standing indication, relying solely on the beeper.

The firmware file for the Goggles L is: AvatarLite_Gnd_xx.xx.xx.
Conclusion
For $199, the Walksnail Goggles L supplies a very good stability of high quality, efficiency, and affordability, making digital FPV extra accessible to a wider viewers. Whereas they lack a number of the superior options and decrease latency of higher-end fashions, their efficiency is commendable, making them a strong selection for these seeking to step into the digital FPV world with no hefty funding.
