ZeroTech Thrive HD Micro Prism 1x20 (prism)
Who tested: Rokslide field eval (2025-07) — read the original write-up, which is the source of record. Who structured it: Optics Intel. We extract outcomes and cite; the testing labor is theirs.
Sample size: 1 (single unit, modified zero-retention-only protocol) — evidence about this unit, not a verdict on every unit shipped.
Stage-by-stage record
| Tracking / RTZ | Not tested | — |
|---|---|---|
| 18″ drops | Pass | drops run as one block — group opened slightly, center stayed zeroed |
| 36″ (single) | Pass | drops run as one block — group opened slightly, center stayed zeroed |
| 3×36″ | Pass | drops run as one block — group opened slightly, center stayed zeroed |

Mount setup
Rings/mount: integrated micro-prism mount, screws degreased. Ring torque: not stated in source. No torque caveat flagged in the source.
Notes
Modified protocol: zeroing and zero retention only. Source attributes the slight group growth to the small mounting screws, not the optic.
