I fish shallow, 25’ or less, most of the time. In summer and winter, I’ll fish deeper vertical jigging on offshore structure and humps. I have been looking at the PS-21 and the PS-22. Is the extra cost of the PS-22 justified for my type of fishing? I like the idea or changing it to down scanning in summer and winter, but honestly don’t know which would be better considering the cone angles and of course the price. Thoughts and knowledge appreciated. Thanks!
