Default Losing bottom while HST in Bahamas

I’ve had an ongoing issue with my bottom Machine losing bottom while wahoo fishing in The Bahamas. My set up is dual Raymarine es128s, cp370 module, and air mar 260 shoot thru ducer. No complaints with my set up any other time holding bottom except when wahoo fishing in The Bahamas going on and off the vertical ledge eventually causes my machine to “lose itself”. After one or 2 passes from 150-400 it pretty much won’t find itself unless I jump up into 80ft or so and ride there for a bit. It doesn’t help matters that navionics doesn’t have the shelf marked correctly so it makes staying in the zone that much more difficult. Anyone have any tips or tricks? I’ve even contemplated going to a 2 or 3k ducer if need be. Thanks!

Can try going with manual depth range, and using the narrowest beam you can for your transducer. The dropoff is so large and so steep it gives really weird returns that understandably confuse the machine when you are right over it.

I agree with Texas 17. I set my screen to 600 ft or so on a manual range. My furuno sounder then seems to track bottom better instead of trying to auto range the depth.

I’ll definitely give that a try.
