The first choice is wrist access versus a separate handheld. Compare G6’s button-led maps with Phantom 3 Slope’s touchscreen and carrying routine, then make sure you can control slope and keep the GPS at the location of your shot.

Keep the distance display where you need it
G6 puts golf information on your wrist; Phantom 3 Slope is a separate handheld that can be carried or mounted appropriately. If you regularly leave your trolley away from the ball, that difference may decide the purchase. A GPS reading describes the device’s location, so a unit left beside a path does not automatically give the same distance as one carried to your shot.
Try your normal routine: park the trolley, take two clubs and walk to a ball position. With the G6, glance at the watch. With the Phantom, decide where it sits securely and how you reach it. Do not assume the magnetic mount attaches to every trolley handle; inspect the intended mounting surface and any compatible accessory first.
G6 emphasises maps and button navigation
The G6 manual documents four-button navigation and full-hole maps, while the manufacturer specification includes hazard and lay-up information with app access without subscription fees. It is a GPS-led watch, rather than a substitute for the V5’s automatic club-tracking package.
Ask to find a lay-up distance on a familiar dogleg, then return to the main green numbers. Do this while wearing the watch rather than holding it close to your face. If the buttons are straightforward under a cuff, G6 may suit a golfer who prefers a physical navigation routine and always wants the distance device with them.
Phantom 3 combines a touchscreen with an optional slope reading
The Phantom 3 Slope specification describes a touchscreen, BITE magnetic mount, green view with movable pin placement and up to six hazard or lay-up distances per hole. Test those screens in the place you would carry the unit; mounting convenience is useful only when you can read and reach it without awkwardly moving your bag.
Moving a pin on a GPS green view does not independently discover today’s flag position. Use available course information and understand what point the display represents. Likewise, a slope-adjusted number is a separate aid from an ordinary horizontal distance, so learn how to distinguish the two before using the unit during a round.
| Habit | G6 consideration | Phantom consideration |
|---|---|---|
| Leave trolley behind | Watch stays with you | Carry unit to the ball |
| Dislike wearing a watch | Try fit before buying | Separate handheld format |
| Prefer physical buttons | Four-button interface | Touchscreen interaction |
| Study the hole | Try full-hole map navigation | Try listed hazard/green views |
| Play under the Rules | Check permitted functions | Know the slope-off setting |
Slope must be controlled for the round being played
The Phantom manual provides a Slope on/off setting. Under R&A Rule 4.3a, getting distance information is generally allowed, but measuring elevation changes is not; a Committee can also prohibit distance-measuring devices through a Local Rule. Switch slope off when required and check the applicable competition instructions.
Do not treat a product’s “tournament legal” description as permission to use every function. Ask the shop to demonstrate the setting and how you can confirm it remains off. This is a small setup task worth resolving before the first tee, where uncertainty can be distracting and unnecessary.
Check the UK package and update route
Confirm the exact colour/model, charging cable, straps or mounting accessories and the seller’s UK warranty route. Both families have app-related functions, including course maintenance; establish that your phone supports the relevant update process even if you prefer to play without looking at a phone.

Choose G6 if wrist access and its map interface simplify your round. Choose Phantom when you prefer a handheld and can keep it with you at the ball. Our G6 guide and Phantom guide provide model-specific background. Neither format establishes an independently measured accuracy advantage in this research comparison.
