Yeah, i have one of those too (X-4), not the best on the market but you get what you pay for, i only bought it for the transducer as my other one was kaput and when it was on sale was cheaper than ordering a new seperate transducer.
All the arguments for and against flasher/fishfinders are going to come up here probably....does every year without fail.
The flasher crew have relaxed a bit since the LX-7 came out and broke their own taboo about using graphs on the ice and all the old myths about freeze up/ lags/power etc..etc...etc...and are actually even a bit smug and delusional on some websites acting as if they invented the concept and now we all need to know about it.
To be honest i would say that both are excellent tools....preference plays a role here too. I hate looking at the whirly circle display and value the 'screen memory' you get using a graph, it gives me a much better feel for how the fish is moving/reacting than when i use a flasher....yes i have used both, my graph fishfinder has a digital flasher and i have used an fl-18 (vexilar).
Drifter made the point about the screen slowing down/freezing and that some flashers have heated screens. This will happen i guess at the temperatures he regularly 'boasts' about (crazy sod) but i have had my graph out all day at -20C and below with none of the issues he mentions(you will want a colour TFT LCD)....even the battery will last for 2 or 3 trips at those temps. So, i dont need a heated screen, so as a feature it is redundant to my needs, cuz any colder than -25C will see in my portable shack for most of the day anyway, no need for a heated screen.
I think Mike hits the nail on the head.....Flashers are a single use tool....although obviously they can and are used on a boats. If you choose the flasher over a graph Marcum and Hummingbird appear to be the most innovative when it comes to flashers, Vexilar appear to be the Yamaha Bravo of the bunch...it will never let you down. Split zoom is your friend.
