Underwater Scooter Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Zcaukya is the best-performing underwater scooter brand in July 2026, moving 1,000 units across 1 ASIN for 32.3% of Top 10 volume. sublue follows with 900 units (29.0%), ahead of Waydoo on 700 units (22.6%).

With 6 brands splitting the Top 10 and 83.9% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $49.99 to $399.00, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0GD6HJCVM booked 100 units at $398.98, with ▲ 100.0% MoM change. On the growth side, B0GD6CP28Z leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B0GD6973X7 close behind at ▲ 100.0% MoM on 200 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
