Grawe's River Gypsy Lure has a strange and different odor that is highly attractive to otters.  It works on natural curiosity and also gives that otter a territorial invasion effect.  The idea with using this lure is to make an otter look for it by using it in a hole about 18" above the water line or using it in an oversized pocket set.  It can also be used at crossovers and trails.

River Gypsy has a loud, rich odor that stays for days and won't wash out. 4 oz. jar.
