FINIS Tempo Trainer Pro Review 2026
The FINIS Tempo Trainer Pro is a small waterproof metronome that clips under your swim cap or goggle strap and beeps at a set interval, giving you an audible target to hold your stroke rate or send-off pace against. It’s a cheap, low-tech tool, but it’s one of the few swim aids coaches consistently recommend for building genuine pacing discipline rather than just guessing at the pace clock.
Key Features
- Adjustable tempo — set the beep interval down to 1/100th of a second, far finer control than a standard pace clock allows
- Multiple modes — including a strokes/strides-per-minute mode useful for building a target cadence in both swim and run drills
- Waterproof and durable — designed to survive full submersion through repeated pool sessions
- Replaceable battery — unlike some cheaper metronome clones, the battery can be swapped rather than the whole unit binned when it dies
- Dryland clip — included for using the same device to pace running intervals or drills out of the water
Does It Actually Work?
A study published in Frontiers in Sports and Active Living tested the Tempo Trainer Pro with experienced competitive age-group swimmers and found it improved stroke control and pacing timing — not just a subjective “feels better” result. Anecdotally, reviewers consistently flag the same trade-off: the beep can be hard to hear over splashing at faster tempos or in busy lanes, but once you tune into it, it removes the guesswork from holding an even pace across a long set, which is exactly where most triathletes lose time in the pool — going out too hard on the first 100m and fading badly by the last.
Who It’s For
Anyone doing structured CSS or threshold swim sets will get more out of a Tempo Trainer than a standard pace clock, because it forces an even, consistent stroke rate rather than a pace that creeps up and down across a long set. It’s less useful for pure technique or drill-focused sessions where stroke rate isn’t the focus.
Buying Tips
- Practice with it on easy swims first before using it in a hard set — getting the beep-to-stroke timing right takes a session or two
- Use the dryland clip to build run cadence awareness too, not just in the pool
- Buy a spare battery in advance — it’s a small watch-style cell that isn’t always in stock locally
Care and Maintenance
Rinse in fresh water after pool sessions to clear chlorine residue from the seals, and check the battery compartment seal periodically — that’s the most common failure point on any waterproof electronic swim device.
