This guide covers what each monitor actually measures, how they compare, and which one to buy depending on your use case.
Ernest Sports ESB1
$350 · 3D Doppler Radar · Entry Level
Entry Launch Monitor · 3D Doppler Radar
Ernest Sports ESB1 REV-D
$350
Best for: Golfers who want real radar data for the minimum spend. The ESB1 tracks the fundamentals accurately and works both indoors and outdoors without calibration.
- 3D Doppler radar, real ball-speed measurement
- Ball speed, launch angle, carry distance, total distance
- Smash factor, club head speed (estimated)
- Works outdoors in all conditions, no setup required
- Compatible with E6 Connect via Bluetooth
The ESB1 is the right buy if you want a launch monitor that gives you real numbers without paying for features you don't use. At $350 it's the most affordable real radar unit on the market. Data is limited vs higher-tier monitors but accurate for the fundamentals.
Ernest Sports ESB2
$495 · Improved Radar · Palm-Sized Portable
Mid-Tier Launch Monitor · Portable Radar
Ernest Sports ESB2
$495
Best for: Golfers who want the extra $145 to go toward better radar accuracy and a more portable form factor. The ESB2 clips to a bag or sits in a pocket, the most portable unit in the lineup.
- Improved radar accuracy over ESB1
- Ball speed, carry, total, launch angle, spin rate
- Palm-sized, clips to golf bag or fits in a pocket
- Works indoors and outdoors, no alignment required
- Bluetooth to E6 Connect and Ernest Sports app
The ESB2 adds meaningful accuracy improvements over the ESB1, particularly for spin rate data. The compact form factor is a genuine advantage, it travels easily and doesn't require a dedicated setup space. For $145 more than the ESB1, the ESB2 is the better buy for most golfers.
What You Get at This Price Point
Ball Speed
Both units track ball speed accurately with 3D Doppler radar. Reliable within 1-2 mph of premium monitors.
Carry Distance
Carry and total distance calculated from ball speed and launch angle. Accurate for most shots, less so on very low shots.
Launch Angle
Horizontal and vertical launch angle tracked on both units. ESB2 is more consistent on off-center strikes.
Spin Rate
ESB2 adds improved spin tracking. ESB1 spin is estimated, not camera-based, treat as directional rather than precise.
Simulator Software
Both connect to E6 Connect via Bluetooth. Limited vs higher-tier monitors but functional for course play and range work.
Outdoor Use
Radar works outdoors without issue. No photometric limitations, bright sunlight, cold, heat, all fine.
When to Step Up to the ES Tour Plus
The Ernest Sports ES Tour Plus at $1,495 is the next step up, a hybrid radar and camera system that adds true club head speed tracking, 20 data parameters, and meaningfully better spin accuracy. If you're using the monitor for serious practice rather than casual range work, the jump from the ESB2 to the Tour Plus is worth considering.
Ernest Sports ES Tour Plus
$1,495, Hybrid radar + camera, 20 data points, club tracking
Our Verdict
At this budget, buy the ESB2. The $145 over the ESB1 buys you better spin tracking and a portable form factor that makes daily use more practical. Both are the right choice if your ceiling is $500, just don't expect club-path data or the consistency of a photometric system. For serious practice, save up for the ES Tour Plus at $1,495.
Frequently Asked Questions
Are sub-$500 launch monitors accurate enough for real practice?
For ball speed, carry distance, and launch angle, yes. Spin rate at this price is estimated (radar) rather than camera-measured. The data is useful for understanding shot patterns but not as precise as $1,500+ units.
Do the ESB1 and ESB2 work indoors?
Yes. Radar works indoors without any special setup. Unlike photometric systems, lighting conditions don't affect accuracy.
What simulator software works with Ernest Sports monitors?
Both the ESB1 and ESB2 connect to E6 Connect via Bluetooth. The Ernest Sports app is also included for basic shot tracking. TGC2019 is not supported.
Is the ESB2 worth $145 more than the ESB1?
Yes, for most buyers. The improved spin accuracy and portable form factor make it the better daily-use monitor. If budget is the absolute constraint and $495 is over it, the ESB1 still delivers real data.
What's the next step up from the ESB2?
The Ernest Sports ES Tour Plus at $1,495. It adds a hybrid radar/camera system, 20 data parameters, true club head speed tracking, and compatibility with more simulator software including TGC2019.
