What They Have in Common
Both use radar-based technology, work indoors and outdoors, connect to GSPro and E6, and don't require special balls or face stickers. Neither will embarrass you in terms of raw data — you're getting ball speed, spin, launch angle, carry distance, and club data from both. The similarities mostly stop there.
Where They Differ
Technology and Tracking
The Mevo Gen 2 uses what FlightScope calls Fusion Tracking — a combination of 3D Doppler radar with synchronized image processing. The Rainmaker is straight Doppler radar. This distinction matters most indoors, where radar units struggle with spin because there's no actual ball flight to track. The Mevo Gen 2's camera component gives it something to look at even in a confined space. I'd guess the Rainmaker's spin numbers are softer indoors than a camera-based or fusion monitor — that's just how single-technology radar tends to behave in a net setup, and Blue Tees even acknowledges it in their documentation.
What You're Actually Paying Over Time
Sticker price: $599 vs $1,299. That's a $700 gap.
The Mevo Gen 2 costs $1,299, includes a lifetime E6 bundle (8 courses), and that's it. No subscription, ever. GSPro integration is included with no additional fee.
The Rainmaker costs $599 but comes with a free first year of the GAME + LAUNCH membership. After year one, you're paying $79/year for sim integration, advanced metrics, and 3D range features. Basic standalone modes remain free.
Three-year total cost: Rainmaker $599 + $158 (two years of membership) = $757. Mevo Gen 2 stays at $1,299.
Five-year total cost: Rainmaker $599 + $316 (four years) = $915. Mevo Gen 2 still $1,299.
By year five, the gap has closed to about $385. Still meaningful, but not the canyon it looks like at purchase. If you stop paying the Rainmaker subscription, you lose sim integration — you're back to standalone practice mode, which is fine for range work but limits indoor simulator use.
Display and Standalone Use
The Rainmaker has a 4.3-inch TFT color display built in. That's a real feature. You can use it at the range without a phone, tablet, or laptop. If your range doesn't have Wi-Fi, or you just don't want to prop a device next to you, the Rainmaker works on its own.
The Mevo Gen 2 has no built-in display. You need the FS Golf app running on iOS, Android, or PC to see your data. That's a minor inconvenience at an outdoor range; it's less minor if you're in a cramped practice bay with no good place to put a tablet.
Software Ecosystem
The Mevo Gen 2's lifetime E6 bundle includes 8 courses — not a huge library, but it's genuinely free and genuinely forever. GSPro integration also comes without an additional fee. FlightScope also offers a shot tracer and video overlay feature, which is more than just data — it's visual swing feedback that the Rainmaker doesn't provide.
The Rainmaker connects to E6 and GSPro, but those connections require the active GAME + LAUNCH membership after year one.
Build and Portability
The Rainmaker is IPX7 waterproof and weighs 1.59 lbs. You can leave it out in the rain. It's built for outdoor range use as much as indoor sim use.
The Mevo Gen 2 comes in under 1 lb and is clearly built for portability, but there's no listed waterproofing rating. The Rainmaker wins the all-weather durability angle outright.
The Mevo Gen 2 also carries only a 12-month warranty. The Rainmaker backs its product for two years — notable given it's a first-generation product from a brand new to launch monitors.
Who Should Buy Which
Blue Tees Rainmaker
- You're primarily an outdoor range golfer who wants real-time data without pulling out your phone every shot — the built-in screen earns its keep here.
- You're on a budget, don't want to spend more than $600 upfront, and you're okay with a $79/year fee after the first year to keep the full feature set.
- You practice in rain or unpredictable weather and need something that won't complain about it.
- You're happy to give a newer brand a shot, especially with a 2-year warranty backing it up.
- Indoor spin accuracy isn't your primary concern — you mostly care about carry distances, ball speed, and smash factor.
FlightScope Mevo Gen 2
- You're building or already have an indoor sim setup and spin accuracy matters to you — the fusion tracking is more reliable in a net than pure radar.
- You hate subscriptions. You want to buy a thing and own it, permanently, including the software.
- Visual feedback is valuable to you — the video overlay and shot tracer give you a swing look that the Rainmaker doesn't offer.
- You're comfortable using a phone or tablet alongside the unit and don't need a standalone display.
- You're buying with a longer time horizon — in a 5-year window, the price gap between these two is roughly $385, and the Mevo Gen 2 continues delivering without any recurring cost.
The Bottom Line
The Mevo Gen 2 is the more capable launch monitor, full stop. FlightScope has the pedigree, fusion tracking handles indoor sessions more honestly, and there's no subscription draining your wallet every January. The Rainmaker surprises with its built-in screen, IPX7 waterproofing, and genuinely competitive price — but this is Blue Tees' first launch monitor, and at $1,299 you're paying for hardware from a company that's been building these for years. If the sim setup is the goal, spend the extra money once rather than trimming every year. If you mostly work at an outdoor range and the $700 gap is real money, the Rainmaker is a reasonable choice — just go in knowing what you're getting.
