The Fitbit Charge 5 fitness band offers back-to-basics swim tracking in a wallet-friendly form factor under $150.

It handles pool length counts, distance, pace and calorie burn metrics alongside 24/7 heart rate monitoring into easily digestible fitness stats, zone minutes, intensity mapping and sleep tracking.

Smart touches like smartphone notifications when paired with an Android or iOS device, swimproof 5 ATM water resistance (covering all recreational depths) and 7-day battery life per charge add to the versatility and value.

However, the slim LED touchscreen sacrifices underwater visibility which could frustrate mid-swim. And while capable of tracking basic movement and heart rate data, the Charge 5 unsurprisingly doesn‘t match pricier options in depth of metrics, customization, open water modes or ancillary capabilities around contactless payments, music storage or animated workouts.

But if you simply want a reasonably accurate snapshot of fitness activity that covers swimming basics across distances and heart rates for under $150, reviewers find the Charge 5 delivers. It also earns high marks for the intuitive Fitbit app‘s data summaries, long-term progress tracking and benchmarking against goals. Just temper expectations for substantial swim-specific optimization or finessed performance statistics.

How to Choose the Right Waterproof Swim Tracker

With core functionality covered, which device best fits your aquatic training needs and budget? These key considerations guide the path:

Check Water Resistance Ratings

Think through what water environments you’ll frequent between pool laps, open water swims or underwater use. Most trackers safely withstand recreational depths around 50 meters but serious divers require 100+ meter ratings with10+ ATM pressure protection. Know the pace of your planned adventures.

Compare Feature Sets

Prioritize what data visibility serves you best – is it lap count, heart rate zones, distance/lengths covered, stroke efficiency or all the above? Do you want guided workouts or just self-monitored sessions? Get clear on must-have metrics versus nice-to-have bonuses.

Assess Battery/Charging Tradeoffs

Frequent charging proves frustrating but extended battery modes sacrifice advanced features. Balance your training schedule against longevity of candidate trackers. If doing multi-hour swims, prioritize higher battery capacities.

Weigh Design Preference

If wearing the device outside training, bigger and brighter displays or more fashion-forward styling may hold greater appeal. But some slimmer, more low profile options trade off visibility. Lightweight builds boost comfort over time.

Set a Budget

Prices span from $100 to $1000 across leading options with core features matching needs available under $300 in most cases. But truly optimized performance often demands $500+ investments. Compare costs against must-haves, training dedication and projected usage lifespans.

Answering these questions crystallizes ideal device criteria for your swimming pursuits and preferences. Ultimately no tracker perfectly nails every need so focus on clear priorities then align with the best matching option. Happy training!
