Default Impulse 4040 Loran/Sonar

I have this unit in the Tiara I bought last year....antennae for Loran is gone but unit seems to work well...especially the sonar/ff.

It would be great to set this up to run beside my HDS7.

Anyone know where I may find an owners manual or instructions how to operate?

1991/92 model

Thanks for any help

It's going to be very hard to find one unless someone has one laying around. I believe impulse went out of business a while ago.

Loran is no more.... it is no longer broadcast, so even if you get the loran antenna, it ain't going to work.

Enjoy your search for a replacement GPS unit.
