This is an update to my previous post "Really Bad Experience with Simrad Purchase" in June 2014. Thanks to one of you in the Trawler Forum I was able to contact the head honchos at Simrad and get my sonar working properly. Apparently High Seas Technologies(HST) never contacted the techs at Simrad to see what the problem was. For 6 months HST kept telling me there was nothing wrong with the NSS12 sonar. When I finally got though to the heads at Simrad they said the software in my system was not updated. While I was in the Bahamas they sent me the update and now it's working fine. I guess you really need to check out your dealer. In this case I was really given a lot of BS from HST. Buyer be ware.
