Mr. Heater Portable Buddy (9,000 BTU)
The blind heater almost everyone ends up owning, and rightly so: 4,000-9,000 BTU, indoor-safe rated, with an oxygen-depletion sensor and tip-over shutoff. It heats a blind fast and has the safety hardware you must have to burn propane in an enclosed space. The default pick.
As a gift
- Why it lands:
- A warm hunter sits still, and a still hunter fills tags. The Portable Buddy is the heater hunters talk about, and the one most of them are still 'getting around to' buying.
- Who it suits:
- Anyone who hunts from a ground blind, box blind or shanty in the cold. Not for a hunter who only sits in an open tree stand - there's nothing to heat.
- Check before buying:
- Make sure it is the indoor-safe model with an oxygen-depletion sensor and tip-over shutoff - those features are the gift. Add a couple of 1 lb propane cylinders (or a hose-and-tank adapter) so it works on day one, and pass along the rule: crack a window, every time.
Strengths
- Indoor-safe rated with an Oxygen Depletion Sensor (auto low-oxygen shutoff)
- Tip-over auto shutoff — critical inside a small blind
- Adjustable 4,000-9,000 BTU heats a hub blind quickly
Trade-offs
- Still requires ventilation — no propane heater is 'set and forget' in a sealed blind
- The 1 lb cylinders it runs on empty fast; a hose-and-tank adapter is worth it

The spec that matters. The only heater specs that matter in an enclosed blind are the safety ones: an Oxygen Depletion Sensor and a tip-over shutoff are non-negotiable, and even with both you must crack a window. Carbon monoxide from burning propane is the real risk — see our safety note below.
