Has anyone used the Duck tactical ascender? I can't seem to find anywhere/anyone that has a ropeman 1 for sale. looking for a alternative that won't damage my tether on linemans. My Brother used my kestrel for the first time saddle hunting while we were in Ohio and decided he had to have it. He is hooked on saddle hunting now. Thing is he got my ropeman 1 when he got my kestrel.
