I have used the zoom in 15 FOW and it does great. You can see a minnow come in.vanwagm said:Last year I bought the 18 for $400. The 8 was $300. After a seasons worth of use, I wish I would have save the $100 and bought the 8. I mostly fish in < 30 FOW for panfish, so the zoom doesn't do much for me. Either way you will wonder how you ever fished without one. I cannot imagine hitting the ice without mine.
