Fish finder sonars

[redboat219]

Has anyone tried using one of those wifi fish finder balls or floats to detect a submerged RC subs?

Curious what it looks on screen, does the fish finder display it as a fish or as distinct sub shape?

Depends on the quality of the fishing sonar
You get. If its side search you can see every detail but side search last time i looked at cabelas was 800$ plus
