does anyone have any experience with zercom in-dash flashers?  there's one on the bost thst I just bought, and I don't have the manual.  The previous owner loved it. 

I've got one in my boat.  Been running fine for the last 12 years.  Only trouble is the light burned out..never bothered to get it fixed.  Only use it while running at speed though.

I still use one for ice fishing - a tri-color - may actually be a zercom. They all work pretty much alike. Look for a flasher in a Cabela's catalog. Serach the net for an owners manual and you may not be too far off.

Close to 20 years ago I had Ranger with a Lowrance flasher on the dash and a Lowrance Paper Chart above it. Haven't had one in a boat since.

They are the best flashers made in my opinion, it is a shame the hummingbird had to go and buy them and screw them up. Wish I still had my old ones.

I have a manual...be glad to copy and send it to you. Email me @ znu2@rochester.rr.com

Javelin200 just emailed me a scanned copy of the manual I needed.  Awesome Job.  Cant wait to pay it forward!
