Hello again, I am looking for reviews on the steadycast heading sensor for echomap 9s chirp sv. I have problems with the GPS that comes with the unit updating too slow. I is very hard to go to a way point and actually get close to where you want to be. Will adding Steadycast help this lag or is it just more accurate. If you have input, good or bad I would love to hear. Would hate to buy install and then be disappointed.
