Talk:Fishfinder

Various points

I came to this page by following the link to Fathometer on the Electronic Chart Display and Information System page, which redirects to here.

According to the intro, a fish finder is a type of fathometer which is a type of echo sounder. Given that these are all similar sytems, differing mainly in just how measurements are displayed, might in be worth merging them all? Especially as this gives more detail about the principles and history of echo sounding than the Echo sounding article.

Also, the figures for speed of sound in water are a inconsistent in presentation: an approximate metric value (1500m/s) for salt water, with an exact Imperial conversion, and an approximate Imperial value (with exact metric conversion) for fresh water. Furthermore, the freshwater value (1463m/s) contradicts the value (1497 m/s at 25 °C) given in Speed of sound#water.

Finally, "Commercial and Naval Fathometers of yesteryear used a Strip Chart Recorder" is inaccurate as these are still used (as indeed the same paragraph states at the end).

History

According to the Financial Times, the fishfinder industry began shortly after World War II, when Kiyotaka Furuno began making them out of surplus sonar equipment originally built for the war by NEC. (See: “Fisherman who caught multibillion-dollar deal,” by Jonathan Soble. Financial Times, December 10, 2009.) Galatians 2:16 (talk) 11:00, 12 December 2009 (UTC)

Life on the bottom

The article talks about finding individual fish swimming above the sea bed, and refers to angling as if that was the only type of fishing to use fishfinders. To be complete, the article needs to cover fishfinding for trawlers and seine fishing, and explaining to what extent fish finders can be used to locate marine life living on the sea floor. —Preceding unsigned comment added by 83.67.149.60 (talk) 11:12, 23 October 2010 (UTC)

That's the problem with merging, you end up losing specifics. Rather than talking about fathometers on one page and fishfinding on another, they decided to focus on fishfinders as an example of fathometers but keep the article broad enough to apply to both. Blame it on lazy/"efficient" editors. 115.130.21.78 (talk) 05:04, 29 November 2011 (UTC)

Undoing multiple revisions

A spammer is editing this article and has made multiple edits. I know I can undo to revert one but if there have been more than one, what is the easiest way to restore to a previous version. Just undo at the first edit since there are no other constructive edits after? Thank you. DrGvago (talk) 08:10, 13 March 2021 (UTC)

Wikipedia is not a shopper's guide. List of company names are of no encyclopediac value. --Wtshymanski (talk) 02:15, 21 March 2021 (UTC)

You have been requested to discuss the concern instead of repeated reverts / edit warring. Please refrain from unconstructive edits and engage to work toward consensus. The manufacturers at the source represent multiple manufactures that provide the newer imaging technologies such as side and down scan. It is not "a shopping guide" nor is any manufacturer highlighted. Further, it is published by a respected magazine relevant to the topic. DrGvago (talk) 02:35, 21 March 2021 (UTC)

Semi-literate ad copy in a magazine that only prints enough editorial content to keep the ads from running together is not a suitable reference for an encyclopedia. --Wtshymanski (talk) 02:00, 25 March 2021 (UTC)
