Models we've catalogued
How to read this. Specs come from each maker's own spec page or datasheet, with the link and the date we checked it. Blank means the maker doesn't publish it (or we haven't found it). Scores are a whirrwork assessment, not a lab test: we only score a model when independent trials or tests exist. Methodology.
| Model | Pipe diameter | Tether / cable length | Assessment |
|---|---|---|---|
| Envirosight ROVVER X Envirosight | 152 to 2,438 mm | 300 to 500 m | Not enough evidence to rate |
