One of the best tools for locating planetary nebula is an OIII filter.
One like this will work very well, what you do is hold it and with an eyepiece with decent eye relief move it in front of your eye and back a few times. This is known as blinking. Normal stars will dim very noticeably, but the PN will not.
If only using for locating an inexpensive OIII filter will do. Bintel used to do a rebadged GSO one, shop around and you may still find one somewhere.
