Its a fine box. Set up to handle sonar..thought it was great...until..I stopped the Kayak..then it was never seen again. Bought a replacement and now "I" secure it with a additional cable. Of It knocked loose while you are going overboard.chances you might hit it with your feet..which I did. The one and only way to secure it..looks good..but does not work well if you tip. Learned lesson. Good news..nothing was inside it.
