Wesmar HD 800-6 sonar. Removed from my boat as it was not working correctly. I believe problem was in the main board and not dome but don’t know for sure. You can’t get parts or service from Wesmar for their legacy products any longer so I went the Furuno route. The hoist and motor is perfect and like new. You can confirm that with Joe Harris Marine Electronics in San Pedro. If you are still using an 800 and want spare parts this is your chance.
