The XM30F at it's price point in terms of build quality, detection range, replaceable battery, recording/sound, wifi, etc is very good, it has a 1300m detection range due to the 30mm lens and 12 micron sensor. Magnesium shell and comes in a super compact design. At that price point the best allround product.
