Synunm portable compound bow press. Really decent and easy portable bit of kit, only selling as I have a full sized bow press in the home now. The rubber tipped hooks will allow to press any bow, although it's not advised by the manufacturer for use with bows with beyond-parallel limbs at brace. But as with all bow presses, don't use unless you know what you're doing.

Pretty self-explanatory to use - you adjust to the right axle-to-axle length with the light green cable, mount the hooks on the limb tips, then press using the dark green pulley cable. 

I'll post Royal Mail special delivery included in the price, or meet at a shoot somewhere.
