A few months back one of our members asked me to write something explaining on ILF bows.
ILF Meaning - International Limb Fitting designed by Hoyt.
ILF is just another way the limb can attach to the riser, period! Some bows limbs are attach by a bolt that's screwed down to the riser, with an ILF attachment, the limb slides into a dovetail and the bolt can be adjusted for shooting 3 fingers under or split finger, the term for this is adjusting tiller. When the bolt is adjusted in it gains poundage and when the bolt is adjusted out it decreases the bows poundage.
Due to the popularity of the limbs attachment several custom bowyers like Bivouac Bows, JavaMan Archery, and Stalker offer custom ILF limbs. These custom ILF limbs come in your choice of woods and weights.
Most shooters will tell you the reason they shoot ILF bows is because there's so many choices in limbs. If you're looking for a new recurve or longbow, don't overlook the ILF limb attachment.
