QYSEA is one of the few underwater robot makers that puts real prices on a checkout page. On 6 August 2026 we read its US store end to end — 34 products, every variant in stock, currency confirmed as USD from the store's own cart endpoint — and cross-checked the same models at two US dealers the same day.
The three vehicles
| Model | Pack | Price | What you get |
|---|---|---|---|
| FIFISH V-EVO | Standard Pack | **$1,399.00** | ROV, 100 m tether spool, controller, box case |
| FIFISH V-EVO | Arm Pack | **$1,699.00** | + 2-finger robotic arm |
| FIFISH V6 EXPERT | Standard Pack (M100) | **$2,999.00** | ROV, 100 m spool, EPP case |
| FIFISH V6 EXPERT | Arm Pack (M100A) | **$3,999.00** | + arm, industrial case |
| FIFISH V6 EXPERT | Extended Range (M200) | **$3,599.00** | 200 m spool, industrial case |
| FIFISH V6 EXPERT | Extended Range Arm (M200A) | **$4,298.00** | + arm |
| FIFISH E-GO | Arm Pack (E200A) | **$7,348.00** | 200 m spool, arm, industrial case, hot-swap battery pair |
| FIFISH E-GO | Extended Operation Arm Pack | **$8,697.00** | + 2 extra batteries, Q-Energy Station |
The first thing to notice is what does *not* change across a 6.2× price range: all three are rated to 100 m depth. What you buy going up the line is payload (2 kg on the V-EVO, 5 kg on the E-GO), light (5,000 lumens vs 10,000), and endurance — the E-GO's hot-swappable 69.12 Wh × 2 pack keeps it working while the batteries change.
The 300-metre tether is range, not depth
QYSEA sells tether spools at $429 (100 m), $679 (200 m, V-EVO/V6 EXPERT) and $1,850 (300 m with carton case; $2,300 with industrial case). Per metre that is $4.29, $3.40 and $6.17 — the curve turns back up, and the third 100 metres alone costs $11.71/m, 2.7× the first hundred. The 300 m spool also costs 1.32× an entire V-EVO.
It is worth being blunt about what that spool does: on a vehicle rated to 100 m, extra tether buys horizontal reach and standoff, not depth. This is the mirror image of what we found at Blue Robotics, where $400 buys a 300 m-rated aluminium hull and the tether to reach it is the expensive part.
The bundles do not follow a rule
Work the pack arithmetic against QYSEA's own accessory list prices and the discounts are all over the place:
- V-EVO Arm Pack: +$300 for a $399 arm → $99 off. The store even shows a compare-at price of $1,798.00, which is exactly $1,399 + $399.
- V6 EXPERT Arm Pack: +$1,000 for a $699 arm plus a $559 industrial case → $258 off (20.5%).
- V6 EXPERT Extended Range: +$600 for a $250 spool upgrade plus the $559 case → $209 off (25.8%).
- V6 EXPERT Extended Range Arm Pack: +$699 over Extended Range, which is the arm's list price to the dollar → no discount.
- E-GO Extended Operation: +$1,349, which is exactly $799 (spare battery pair) + $550 (Q-Energy Station) → no discount.
The same $699 robotic arm is discounted in one pack on the V6 EXPERT page and sold at full list in another pack on the same page. Buyers who assume "the bundle always saves money" will overpay on two of the five.
Factory store vs dealer, same day
At UrbanDrones, an authorised US dealer, the vehicles track the factory almost exactly — V-EVO identical, V6 EXPERT M100A/M200/M200A identical, E-GO E200A identical — with two exceptions in the buyer's favour: the V6 EXPERT base pack is $2,900 (−$99) and the top E-GO pack is $8,589 (−$108).
The accessories are a different story. The 500 mL water sampler is $699 at the factory store and $1,099 at the dealer (+57.2%); the external Q-Camera is $1,099 vs $1,399 (+27.3%). Others — Q-iRC controller $1,850, GNSS locator $1,600, laser scaler $499, mud sampler $1,680 — match to the dollar.
The dealer also stocks configurations the factory store simply does not list: an E-GO E100 at $6,499, V6 EXPERT MP200 at $6,199 and EP300 at $12,299, a larger E-MASTER at $10,927 ($17,728 with navigation), and a bank of V6 EXPERT water-quality sensors (dissolved oxygen $2,899, pH $4,499, salinity $4,899, turbidity $5,899) that never appear on qysea.com. One of them is not hardware at all: QYMT, an AI measurement system sold as a subscription at $3,999 for six months or $5,999 for a year.
What a working E-GO actually costs
Take the $8,697 pack and add the tools an inspection job tends to need — Q-iRC controller $1,850, Q-Camera $1,099, 360° camera $1,550, laser scaler $499, metal detector $399, mud sampler $1,680, GNSS locator $1,600, 300 m spool with industrial case $2,300 — and you are at $19,674.00, or 2.26× the sticker. Above that, the ladder keeps going: Blue Skies Drone Shop lists a FIFISH X1 Mission ROV at $96,000 and an E-Series direct power supply system at $20,000.

Limitations. All prices are add-to-cart listings read on a single day; QYSEA and its dealers change them. Pack contents come from the manufacturer's own product pages. The "working E-GO" total is our basket, not a quoted configuration — your job may need fewer tools, or a sonar the store does not sell.
