These are the two most interesting sim-capable units under $1,000, and they take opposite technical paths. The MLM2PRO is a radar-and-camera hybrid with the deepest feature set at the price. The Square is the only camera-based launch monitor under $1,000, trading flexibility for accuracy. The decision comes down to where you play and how you feel about a subscription.

Indoor-outdoor reach versus camera accuracy

The MLM2PRO's hybrid design works indoors and outdoors, adds swing video with a tracer, and opens a library of 30,000-plus courses, which is why it scores 8.0 on features. The Square is indoor only, but its photometric cameras and infrared sensors buy accuracy: it scores 8.0 on accuracy to the MLM2PRO's 7.0, with standout ball data and putting, and it works in tight spaces. If you have a dedicated bay, the Square is the more precise instrument; if you also practice outdoors or want swing video, the MLM2PRO reaches places the Square cannot.

The subscription decides the true cost

Sticker price favors the MLM2PRO ($599.99 to the Square's $699.99), but the recurring cost flips it. The MLM2PRO's Premium tier is effectively mandatory for simulator play, $199.99 a year after a trial, while the Square carries no subscription and no connector fee, including for GSPro. Over three years that gap is roughly $600, which more than erases the Square's higher upfront price. Other catches: the MLM2PRO's measured spin needs special RPT balls and driver distance can drift a few yards, while the Square's native software is thinner than the big brands and it wants marked balls for best spin.

Who each one is for

• Rapsodo MLM2PRO: buyers who practice both indoors and outdoors, want swing video and a huge course library, and will pay the yearly subscription for it.
• Square Golf: indoor sim builders who want higher measured accuracy, great putting, tight-space operation, and zero recurring fees.

The verdict

For a dedicated indoor bay where accuracy and true cost matter, the Square is the stronger buy: higher accuracy and no subscription, which wins on three-year cost despite the higher sticker. For a player who also hits outdoors and wants swing video and course variety, the MLM2PRO is the more flexible box, as long as the $199-a-year Premium tier is acceptable. Buy the Square for indoor precision and no fees; buy the MLM2PRO for indoor-outdoor reach and video.
