After years of work I finally completed our map project and with friends requesting support for Humminbird I was able to make something work.

I did have to invest in Hummibird software "Auto Chart Pro" ( ~$200 US ), and then after exporting all the imported trails from Reefmaster as Humminbird trails, I imported into Auto Chart and create a map.

I did notice while exporting from ReefMaster it would leave random points through out the map and I would have to manually clean, but the finished product turned out pretty nice. I can now do contour follow with the minn kota trolling motors. Now if there was only a solution for Garmin...

Can you explain how you do ?

- export the RM datas as csv (best all together as one single csv)
- in Autochart: "import/convert" the csv-files (results will be internal acd-files)
- map editing and creation in Autochart for later use in a HB unit (use the Autochart manual)

I’ve thought about getting Autochart Pro. Unless I’m wrong it’s a watered down version of the now discontinued DrDepth.
