Used on 2 different boats – SonarPhone by Vexilar Review

Sonar reading is inconsistent. Forget about making a map while using navionics. Temperature sensor constantly reads 122 degrees. I have installed this on 2 boats. Freshwater or saltwater. Inconsistent in both applications. Save your $$$$. And do not purchase. Btw. Your last update did not help. I phone 6s plus.
