Review on Vexilar SP200 T Box Smartphone Finder by Terrance Duncan

I installed this in the cargo area of a 2019 Yamaha Waverunner VXR. I used a 1" RAM "dash" ball mount to the left of the VXR's dash and an anodized aluminum motorcycle handlebar cell phone mount to mount my phone. I used RTV silicone sealant to attach the gauge to the dash. in the hull, on the opposite side of the water box, being careful to choose a spot that didn't touch the bottom plate so there would be no interference. I then used strong plastic Velcro to attach the T-Box receiver to the chassis, just above the battery which is under the rearmost seat. It eliminated the need for a bulky sonar, allowed the transducer to fit through the case, allowed me to use my phone with my Navionics app (which the sonar app is built into) and while driving via my waterproof Bluetooth headphones to listen to music. further.
