Oh yes!! they work, sounds like a fluke, but they work... years ago practice day of bass torunament I used mine and it said to throw purple bait, so I tied on DBII crankbait in purple and about 6 casts later landed an 8lb bass... and I never would of thrown that color for nothing,even tho I had it in box!!! So, I am a believer...kinda wish I still had one. yrs ago I paid around 80.00 for it!
