G'Day, I need an electronics guru... The male pins in the plug of my Dragonfly 7 have corroded and snapped off. From a bit of googling, this seems to be a common problem with this unit. I have been in touch with the national distributor, and their nominated repairer, as well as a couple of marine electronics places locally and the message is the same. Sealed unit, built to a price, and cannot be repaired. This is bloody annoying as I like the unit, yes cheap and cheerful, but does a very good job in shallow stuff (<30m), and on my boat it sits neatly beside my Lowrance unit and they don't interfere with one another while sounding, in fact work very well together, giving me a large number of combinations of functions. Long story short, I don't want to bin the Dragonfly if I can help it! Does anyone have any ideas? Surely it can't be that hard to replace a plug? Any and all help or suggestions gratefully received.
