importance of having electronics

[KCMO CRAPPIESLAYER]

hello fellow slabhunters!

i have another question out there for everyone. obviously electronics and more advanced technology are a major advantage we as fishermen have now. what i want to know is how much am i missing out on. iv'e pretty much became a full time crappie fisherman, and i know i've got a ton to learn. i use a fish eagle mark 480 that i purchased just last year. i did'nt want to spend much and i did a lot of research on them and i decided with that one. just how important is having gps, color screen, thermocline, barometric pressure(if there is such one)also the newer ones that show sideviews, and all the added features that come with a more expensive one. will it help me that much more? i just have a 15' aluminum lowe with a 15 horsepower 2 stroke, nothing fancy. but it's kind of like when i was in highschool, i drove a ford fiesta i paid $300 for and had $1000 speakers lying in the hatchback, so if having a more advanced fishfinder is gonna make me a better crappie fisherman then maybe i need to start looking around. thanks for any advice
