robotindex QYSEA FIFISH V-EVO
A six-thruster, 100m-rated underwater ROV from Shenzhen QYSEA Technology, marketed as a "Smart Dive Companion" for content creation, light exploration, and basic recovery. Despite QYSEA's broader FIFISH line skewing professional, V-EVO is specifically the entry-level model in QYSEA's own current lineup — it sits below V6 Expert and the industrial-flagship E-GO, and undercuts both Chasing's M2 S and Geneinno's T1 Pro on price by a wide margin.

Specs
Battery
9000mAh / 97.2Whmarketed "4 hours" is a hovering/idle figure — QYSEA's own numbers put full-mobility runtime closer to 1 hour; not user-swappable
Weight
4.1–4.6 kg (ROV only)New Atlas reports 4.1kg; B&H's spec sheet lists 4.6kg, identical to V6 Expert's published weight — possibly a copy-paste spec error on B&H's part, unresolved
Camera
12MP / 4K@60fps1/2.3" Sony CMOS, f/2.5, 166° FOV, JPEG + DNG RAW stills; no optical zoom, no 8K
Depth Rating
100 m (328 ft)QYSEA explicitly states this stays constant regardless of tether length — a positive contrast to a mislabeling pattern found on competitor listings
Thrusters
6, omnidirectionalfewer than Chasing M2 S's 8, matching Geneinno T1 Pro's 6
Tether
100m included200m ($679) and 300m ($1,850) spools sold separately, purely for surface reach — not depth
Control
App + bundled remote controlleroptional $29.99 VR headset is a phone-holder shell using the phone's own screen and gyroscope, not an independent HD FPV feed
Lighting
~5,000 lumens combinedtwo forward LEDs at 5,500K
Accessories
2-finger gripper arm (+$300)plus retrieval hook, prop guards (sold separately), camera mounts; no sonar, no external camera module, no GPS locator — those live one tier up on V6 Expert
Subscription
Free, no subscription foundFIFISH app (iOS/Android) lists no in-app purchases or paid tiers; no cloud video storage or editing subscription identified for V-EVO
Reference Price
V-EVO launched at $1,299 in 2023 and currently lists at $1,399 (Standard) / $1,699 (Arm Pack) on QYSEA's own store — a modest increase over launch pricing rather than a real conflict across sources. The announcement date itself has a minor discrepancy worth noting: QYSEA's own press page carries 2022 in its metadata while New Atlas and PetaPixel's launch coverage runs April 2023, most likely reflecting an internal announcement followed by wider press coverage the following year.
Insights
QYSEA's own numbers show V-EVO's advertised "4 hour" battery life is a hovering/idle figure — full-mobility active piloting drains it closer to 1 hour, a real gap between the marketed number and real-world use. The bundled "VR Control" feature is similarly overstated by its name: it's a $29.99 Cardboard-style phone holder that mirrors the regular app's live feed using the phone's own gyroscope for head-tracking, not a dedicated low-latency FPV headset with its own video pipeline.
Firmware & Community
Closed platform
QYSEA FIFISH V-EVO has not released a public SDK, firmware repo, or developer API. Not currently listed in Builds & Mods.
Specs compiled from QYSEA's own product and store pages (qysea.com, store.qysea.com), B&H Photo's spec listing, and launch coverage from New Atlas and PetaPixel. Flagged as unconfirmed or conflicting above: V-EVO's exact weight (4.1kg vs. 4.6kg across sources), exact announcement date (2022 vs. April 2023), charging time (not found for this specific model), tether buoyancy, and whether V-EVO holds its own FCC equipment certification. This entry hasn't yet been cross-linked or synced to the directory listing; that's planned for a later pass.
