I was probably one of the first float tubers to ever use a sonar on my tube. Way back in the early 80's I rigged an old flasher unit with dual 6 volt lantern batteries in series and just balanced the display on the front of my tube. Since then I have bought and used maybe 20 different sonar setups...trying to find the best for tubing. A lot of the low end early models just showed little fishy symbols...for everything from tree branches to gas bubbles...to fish. Our more sophisticated modern systems are more definitive...especially the color models.
I also have a Garmin Stryker on my tube...a model 7. And I can assure you that not seeing inverted Vs on your screen is common with slow moving or stationary float tubes. The V marks show up mostly when you are moving over the water and the sonar signal moves along a fish...with an air bladder...to produce the characteristic mark. If I am moving with any speed using my electric motor the marks I see are different than when slowly kicking or fishing stationary.
As with all systems, you will learn to translate what you are seeing on your screen into useable info for making presentations and catching more fish. The frustrating part is seeing fish and not catching them. That's fishing.
