Is the Pulsar Telos LRF XL50 worth it?

For hunters who need thermal imaging and distance readings in one device, yes. For occasional night viewing, a cheaper monocular without a rangefinder is usually enough.

Does it come with a battery?

It runs on a rechargeable battery pack, which is normally included. Check the box contents with the seller before ordering.

How far can it detect animals?

The 640x480 sensor and 50 mm lens give detection ranges of several hundred meters for large game, with identification at shorter distances.

Is it better than a thermal monocular without a rangefinder?

It saves carrying a separate rangefinder and gives distance readings in the same view. The trade-off is more weight and a higher outlay.

How does the XL50 compare with the XQ38 version?

The XL50 pairs a 640x480 sensor with a 50 mm lens, while the XQ38 uses a lower-resolution 384x288 sensor and a 38 mm lens. The XL50 resolves more detail at long range; the XQ38 is smaller and lighter.
