I have never owned a flasher and respect everyone that prefers them over the graph. I agree that the target separation on the bottom is more precise (Maybe a few inches at most) and you can see fish better hugging to the bottom with that properly adjusted flasher. That being said, I probably will never own a flasher, as other than those fish tight to the bottom, if you are good with your graph and can set your color-line and sensitivity per the depth and water column you are fishing, I am confident you will meet or possibly exceed many that run a flasher. I have learned to see fish outside of the cone angle when they come in by noticing the fish show an echo "below" the bottom line. This is by having my color-line set just right. Not all bottoms I can do this but for sure on softer bottoms.
I have the Elite 5 Ice pack and honestly am very pleased. I have it set up to mount on my snowmobile with a Ram mount and find the graph with maps extremely valuable for getting to the right spot. I can use my transducer off the sled as well when fishing outside. I can disconnect the bracket and have connected in my icepack for the portable house in literally 30 seconds. If you are a flasher guy, you will need to play with it to get used to it. Some love it and others simply prefer their flashers....I get it. The last and most important thing for me is seeing the history of fish if you look away to rig or eat etc...I prefer not to glare at my fish-finder continuously and with the history a graph provides, you can see several seconds of time lapse letting you know there is a fish nearby.
For you, you can have the best of both worlds....have the flasher available as a backup or the graph as your backup....added the value of a mapped GPS for returning to a spot or finding a new spot on a strategic contour of the lake....good luck!
