Question: We are looking at sonar options for use in areas with poor charts and low visibility. Our interest is primarily for checking anchorages and narrow passages, looking for obstructions. We have a small plotter/sounder in the dinghy, but nobody wants to go out in the dink when it is cold and rainy (and warm and dry on the big boat!).
I have heard a rumour that you guys have an EchoPilot unit:
- How do you like it and how does it work?
- What do you do in a tight anchorage for checking what is around you?
- Is there a problem crossing your own wake at dead slow speeds?
- Where have you mounted the transducer and is it vulnerable to ice and debris? In our case, it would be on center, 16′ aft of the bow (in our forward watertight compartment) or centered fore and aft, offset to one side about 5′ and alongside one of the stabilizer fins (which reside in sealed coffer dams).
- Have you used it in the tropics with coral? I assume it would work well with the abrupt shape of the coral heads.
- Can you tell anything about bottom composition, i.e. mud vs. rock or kelp?
- Is it any good in ice?
- What do you do for a depth sounder? Use this, or something more specialized?
