[PSUBS-MAILIST] progress report

[Alan James via Personal_Submersibles]

Yes it would & it might show a boat hull if it just happenedto be within it's cone, but it seems an expensive, less reliable& more difficult option to set up than a pressure gauge, which would also tell youwhat depth you are. I have mentioned this idea, but will repeat it.... If you build a small view portabout 2" diameter & place a fiberglass disk about 1/2" in it, you could mount your transducer on the inside of your hull & "shoot through" the fiberglass.Google "shoot through hull transducer" if you are interested.Cheers Alan

Alan,    What do you mean "pressure gauge"  , wouldn't the sonar bounce off the surface of the water? Brian

Brian,if you wanted to save money you could just buy the transducer & mount it on your sub& take the display module from your boat whenever you needed it.I am waiting to hear back from Navico about the suitability of their forward scanning transducerwith regard to depth rating or it's ability to shoot through a fiberglass enclosure.This would be a good option if it works out, as it gives collision avoidance at a reasonable price.I don't think there would be any advantage scanning upward, over a pressure gauge that gives youdepth readings.

Just bought a Garmin echoMap Chirp 44dv  mapping gps and sonar for my sailboat , I'm thinking maybe getting another one for the sub !   I wonder if you had the transducer on a swivel what the image would look like pointing to the surface ?  https://buy.garmin.com/en-US/US/on-the-water/fishfindergpscombos/echomap-chirp-44dv/prod529866.html Also, I've got another sailboat keel ( solid lead ! ) lined up to get for next week !   It's off of a 29' Ericson, it's a pity, this boat is being demolished because they didn't pay their slip fee !  Nothing wrong with the boat.   It's probably a good 3000 lbs of lead !  .50/lb  Cheers, Brian
