I'm a biologist that's fished my whole life, but only short stints with cheap (<$200) fish finders, of which I've found to be pretty useless. I like the idea of installing a current lowrance on the PA14 and want to give one a try.
Currently on the fence with both:
-Elite 5 vs. Elite 7, and
-Chirp vs. HDI
I primarily fish shallow (5-15') freshwater for largemouth/snakehead, and intertidal estuaries (also shallow) for flounder and stripers. Occasionally I will chase things like landlocked stripers in deeper reservoirs, but definitely not often.
Cost is not an issue, but I'd like to justify the difference between the $349 Elite-5 HDI and $799 Elite-7 Chirp.
I've read a ton (hull truth article, etc.), watched all the youtube videos, and so forth- still not totally convinced.
