    Dual Beam WiFi fish finder technology you can share with friends

    The SP200 Permanent Mount system is designed for installation in boats with easy access to a 12 volt power supply (not included).

    As the name implies, SonarPhone turns your smart phone or tablet into a fully functional sonar system that will rival any high end sonar on the market today. Using Patented WiFi signal technology to transmit to smart phones or tablets. You don’t need cell phone coverage to use it, the SonarPhone will work anywhere in the world. The SonarPhone T-BOX creates its own WiFi hotspot and you can share your signal with as many people as you wish, the software App is downloaded for free from the App Store or Google Play and works with both Android and IOS systems.

    With the powerful SP200 T-BOX system, you can reach depths of 240 feet with a 200kHz, Dual-Beam (20/40 degree) skimmer style transducer and temp sensor. The Skimmer style transducer can be mounted externally on the transom of your boat for high speed use or internally in fiberglass hulls, but you will lose the temp sensor option for in-hull installations.

    Also included in the SP200 package is a 12 volt car plug/USB adaptor for powering your tablets or re-charging your phones.

    Water resistance rating is IP66.

    The SP200 also comes with a FREE neoprene arm band ($19.95 value) so you will have easy and safe access to your phone display at all times. - See more at:

    Depth limit.

    Technology is neat, but it has a depth limit of 240'. It would work great in the shallow lakes in the Mid-west, but the deep lakes of CA it is not good. I can use this Bass fishing along the shore, but not for trolling in the deep water. Some of the lakes I fish are 300+ feet deep. Would be great if SonarPhone offered a new transducer that can work in deep water.

    Works as advertised

    Use with my Navonic's app on my iPad. Works great.

    Would be great if it connected using blue tooth; useless using wifi

    Since it is only possible to have one wifi connection at a time, and since iPhones & iPads won't connect to the internet if they are connected to wifi it makes the T-Box useless using with Navianics. My Navionics chartplotting app keeps saying I don't have a current account and won't let me see the chart until I purchase a current plan. I've found that if I open Navionics while connected to the internet through the cell carrier, let it stay on for a few minutes and then connect to the T-Box wifi it will work--but keeps constantly saying there is no internet connection so can't do whatever I'm trying to do. Maybe if you used the sonar phone app it would work--don't know, haven't tried it' but I got it to use within Navionics and for that it's useless since it connects using wifi.



    Vorrei acquistarlo .A bordo ho Lowrenz e lite 5 come ecoscandaglio spero che il t box 200 potrà indicarmi meglio il fondale e i pesci.

    Excellent value

    Since I already had an Android tablet, this $150 investment provided me an equivalent system to a $500-$750 color GPS/Sonar combo. I have been a marine electronics "power user" ever since Humminbird came out with Side Imaging, but they (and all the other major manufacturers) have priced most folks out of the market. This system was exactly what I was looking for for the bow of my new bay boat - and highly affordable. And don't ever think this is not serious equipment - the quality of the sonar returns I am getting are easily as good as the 2D display on the $2000 unit at the console. Thanks Vexilar!!!!!
