Got this sounder after doing some research, seemed like a really good deal. Well it's a great deal, excellent value for the money (just look around). Went with the epoxy in hull mount and it works like a champ. Delivers clear accurate information and the adjustable alarms are very helpful. No more running aground on evenings when its a little dark when we are headed back to the dock. If you need or want one this is a good choice.
