Current U.S. variant prices and specifications for GS03/GS03MTL and ZeroIn were checked October 21, 2026. Independent test coverage for GS03 dates to 2023–24; ZeroIn has a 2026 test.
Quick answer
For most golfers choosing between these two GOGOGO lines, the GS03MTL is the value pick at $109.99: it has a visible slope switch, cart magnet and replaceable CR2 battery. The ZeroIn costs $149.99 and is the better upgrade if you want USB-C charging and the model with newer independent accuracy-and-speed testing. If you do not need slope or a magnet, the standard GS03 is listed at $79.99.
Code SEBASTIANBASSOL is supplied for 5% off eligible purchases. That estimates about $5.50 off GS03MTL or $7.50 off ZeroIn, leaving a roughly $38 difference after code if both variants qualify.

Why choose GS03MTL?
The GS03MTL gives you the key rangefinder functions at a lower price, then adds the two extras that distinguish it from the basic GS03: a physical slope switch and cart magnet. Its CR2 battery is easy to replace, so you do not need to manage a charging cable. If those are the features you need, the $40 price gap to ZeroIn can stay in your pocket.
Golf Monthly’s 2024 GS03 test reported readings within about 0.2 yard of its Bushnell Tour V3 comparator, but its basic mode could need a second aim on flags; flag-lock mode and vibration helped. Plugged In Golf’s 2023 GS03 test reported unadjusted results within one yard of two other lasers and noted that slope-adjusted results could differ at longer distances. Read our GOGOGO GS03 MTL review for the full recommendation.
Why pay more for ZeroIn?
ZeroIn is the better fit if you want rechargeable convenience or prefer the stronger current performance evidence. An independent 2026 rangefinder test found a strong combined score for accuracy and speed, with optics and display trailing much of the field. See our GOGOGO ZeroIn review for the measured trade-off.
The ZeroIn is about $40 more than GS03MTL before code and about $38 more after the estimated 5% code savings.
Which model should you choose?
- Choose GS03 if the lowest price matters and you do not need a slope switch or cart magnet.
- Choose GS03MTL if you want those two physical controls, prefer replaceable CR2 power and want to keep the price near $110.
- Choose ZeroIn if you want USB-C charging and newer third-party performance evidence and are comfortable paying about $40 more.
