Pinpoint 7520
Shortly after the "In Synch" technology was introduced, I bought two 7520's and networked them together to do the split screen front/back feature.....well, to make a long story short, I went through a total of 8 units before I became so fed up and sent the stuff back and bought lowrance. Wish I could run both of my X-15's together without the dual frequency x-ducer, but the resolution is really nice on the 15's...I guess ya can't have everything.
Anyway, I know I'm off the subject of your post and I didn't post this with the intention of bashing you or any pinpoint owners...just wanted to share that bit of the story.
