Danny, the triathlete behind Tri_To_Be_Iron, tried HoloSwim 3 Pro in two settings: the pool and open water. His main question was a practical one. Could the compass help him hold a straighter course without forcing him to lift his head quite so often?

Based on the sessions covered in Danny's YouTube review, the answer was mostly yes. The compass became the feature he valued most.

What Danny Liked

The compass helped him catch directional drift

Danny's open-water routine was straightforward. He sighted the buoy, checked the bearing displayed inside the goggles, and then watched that number as he continued swimming. A change in the bearing gave him an early indication that he was drifting left or right.

It did not eliminate sighting. Danny still lifted his head to confirm the buoy and check his surroundings. The compass simply gave him another reference between those visual checks.

Once he grew comfortable with it, he felt he could sight less frequently. For a triathlete trying to avoid unnecessary head movement while still staying aware of his course, that was the clearest benefit in his test.

"It took me probably three quarters of a lap really to start getting used to not sighting as much because that's what you're used to doing and actually trusting the device, but it works." 

The display stayed in the background when he did not need it

Danny had previously owned first-generation FORM goggles but sold them because he found the peripheral view too restricted. His experience with HoloSwim 3 Pro was different.

He could look toward the display when he wanted the bearing or other information, then let it fade into the background as he swam.

That comparison applies only to the older pair he owned; it is not an assessment of current FORM models.

The goggles worked well for him as ordinary goggles

Smart features matter only if the goggles still handle the basics. In Danny's sessions, they did. He found them comfortable, reported no fog during the open-water swim, and experienced no leaking during his pool test. Initial pairing was also quick.

What Took More Work

Reading the compass was not immediately natural

Danny needed roughly three-quarters of a pool length before he felt comfortable watching the bearing while swimming. That is not a long adjustment period, but it does mean the experience was not completely instinctive from the first stroke.

A new user would be better off learning the display in the pool before depending on it during an open-water session.

The recorded distance differed from his watch

Danny saw a difference of roughly 100 meters between the goggles and his watch. He did not have an independently measured reference, so his review could not establish which device was closer to the actual distance.

For swimmers who record the same session on two devices, this is worth watching over several swims on known routes. One comparison is useful, but it is not enough to judge accuracy.

Smart goggles bring another training device into the routine

HoloSwim 3 Pro needs to be charged, configured, and used with its supporting software. Direct TrainingPeaks upload was not available when Danny recorded his review. He also found the automated training suggestions less useful because he already follows a coach-led training plan.

That does not make the feature unnecessary for everyone. A self-coached swimmer may get more value from it. Danny simply did not need another system telling him what to do next.

Who Is HoloSwim 3 Pro Best For?

Danny's experience makes the strongest case for triathletes and open-water swimmers who want live directional feedback and intend to review their swim data afterward.

The compass is particularly relevant for someone who already knows how to sight correctly but wants another indication of drift between sightings. It supports that skill; it does not replace it.

"These goggles are probably perfect for triathletes, perfect for data lovers, perfect for swimmers who like to do open water swimming and structured swimming training." 

The goggles may also suit swimmers who train alone and have a clear use for in-lens information. The data needs a purpose. If seeing it helps you correct your heading, manage a training set, or discuss a session with your coach, the display becomes part of the workout rather than something you stop noticing after the first week.

Occasional swimmers may see less value, especially if standard goggles already meet their needs. The same applies to athletes who do not want another device to charge and maintain.

Fit is personal, too. HoloSwim 3 Pro includes eight interchangeable nose bridges, which provide several adjustment options. Gasket contact and overall comfort will still depend on the individual.

Danny's Verdict

For Danny, the compass was the most valuable feature. It helped him recognize left-right drift earlier and reduced how often he felt he needed to lift his head, while the readable display, comfortable fit, and reliable seal supported the experience.

The tradeoffs were practical: a learning curve, a distance discrepancy with his watch, and another device and app to maintain. HoloSwim 3 Pro did not replace sighting, coaching, technique work, or open-water awareness. However, for triathletes who want live directional feedback and will use the data in training, his test showed a clear and realistic benefit.
