How we calculate scores →About this gear
The hw Bottomtimer is a dedicated depth-and-time instrument with a 2.4-inch IPS display, two buttons and an aluminium housing. It records depth, elapsed time, averages and temperature, with a separate stopwatch. A replaceable AA battery and optional scooter mounts are practical distinctions from a sealed disposable instrument.
Consider before buying
It does not calculate a decompression schedule. The current manufacturer page lists no connections; a 2022 review mentions a maintenance port but says dive-log export is unavailable. Check the exact scooter mount: the standard SUEX option explicitly excludes Quantum.
Our take
Unterwasserwelt praised readability and simple controls, while noting that its tested Bonex mounting was not quick to remove. Choose it as a planned backup or dedicated instrument, not as a replacement for decompression functionality. The review supplies no overall numeric grade.

hw Bottomtimer: scooter-mounted and wrist use ↗
The reviewer liked the clear display, two-button operation and replaceable battery. The tested Bonex mount was not quick to remove, and log export was unavailable.
