Under 100$ the lowrance x4 pro is what I've been using for 3 years! I upgraded to an ice transducer this year but I didn't really need to it was 60$ and just made its use much simpler ! You really don't need to spend a few hundred at all! I fish from 10 to 120' for trout no problem at all! Portable too so you can use it on your boat if you have one
