Nick Tophamwrote a review of TYR Hydrofoil Pull Float on May 3, 2019
Familiarity: I've used it once or twice and have initial impressions
This is a nice little pull buoy. Slightly more aerodynamic and feels a little more comfortable. I can't say that it is essential by any means, but I like it better than the classic floats that are common to public pools. Not sure how much more you can innovate on a pretty simple piece of gear.
