The 2038 open reflex variant re‑configures motion‑sensor sleep‑timer parameter to 8‑minute idle timeout. This is a user‑requested niche improvement for hunters and observers with frequent long stationary waiting periods. All optical hardware, housing and waterproof / shock‑proof specs are consistent with base HD‑101 open‑dot platform, only firmware sleep‑timer setting differs. This SKU gives distributors a differentiated open‑frame reflex without new mold investment.
