I have a larger locking instrument box that does not fit my boat. It is 13" tall, 6" deep at the top, and 10" deep at the bottom by 17" wide across the front. It has a large door that you can secure with a padlock, would house your Radar GPS and Sounder all at once, someone would need a sawzall to get your stuff. I paid $100 for someone to weld it up to totally not the measurements I gave him, so I'm open to offers.
