It could be used to use to tell the depth where the fish are at but you really need a vexilar flasher. I've had an 8 for a couple years now and would never go without it. If you have the cash get a flasher and an a tbox and never look back. **Q: Does the entire unit attach to the side of the boat? what is the all the wire used for that i see in the photo. i want to use it on my 20 foot searay** A: Just the transducer attaches to the boat I keep the smart box up front ( for the power button and recharge) in a 17' **Q: how long will it last on a charge?** A: Jake,That item will last 15 hours per charge.Thanks for asking.Very respectfully,Mike **Q: is this unit made for ice fishing / or is it just made for boat fishing ?** A: This unit can be used ice fishing. Though it is designed to be used from a boat, you could suspend the transducer in an ice hole. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saves me from certain DEATH! *by S***L on March 30, 2016* This might possibly be the coolest thing ever for cruising. When I'm entering a poorly charted anchorage, I can stand offshore with the big boat and then I can scount around in my dinghy with this and my gps-enabled tablet running Navionics Boating HD and I get an updated realtime chart complete with bathymetry! I take that back to the big boat and enter the anchorage with confidence. Works awesome in the Bahamas where some of the better spots take some exploration to get into.Only thing I've noticed is the charging indicator is a little unclear on what the charge status is. But who cares, really. I LOVE THIS PRODUCT.For years I imagined of creating just this product. Someone went ahead and did it and I'm so glad!Note that if you want to use an ipad, you'll need one of the cellular-enabled models to have the GPS capability you'll need. ### ⭐ Out of the box frustration... *by J***E on January 11, 2018* Update: As a verified purchaser I can tell you these things. 1. There are no instructions with this unit. 2. There is not even a Quick Start Guide. 3. This will NOT connect to an iPhone 8, with Version 11 software.The connection to this unit is via WIFI, not bluetooth which presents some challenges. You need to find the PASSWORD. This is where lack of instructions and quick start guide become an issue. I had some conversations with their tech support, and was able to connect an old iPad to it but not an iPhone. I would go into iPhone settings and connect, but once the App was opened it would not connect. But thats not what I purchase if for, so it's going back.There is a good market for a fish finder like this, but Vexilar is not the one. ### ⭐⭐ Not a good experience for me *by S***. on June 28, 2016* I don't particularly like writing negative reviews but I did not have too much luck with the T-Box. It has a lot of good things going for it and the concept is good, but for me, I had a not so good experience. When I received the box, I felt as if it had been opened. The box was a little battered and I just had a gut feeling. I used it for kayak fishing. I loved the fact that it's portable. The T-Box uses an app on your phone as the fish monitor. On the app, there is a battery level indicator. After initially charging overnight, the battery indicator on the app only showed half charge. After subsequent charges, it never moved from that position. Does it actually work as a fishfinder? Yes, it does it's job and using your phone as the monitor is pretty cool. Most phones do not work well in bright light. Expect to have to deal with that. Many times you just cannot hardly see your phone screen and you will have to try and shade it to see fishfinder. Also, make sure your phone or iPad is in a waterproof case of some kind. That will usually make it harder to see as well. You will need a backup power supply on board for your phone as well because the battery will discharge pretty fast. The most time usage I ever got from the T-Box was around 4 hours. After that, the battery died. After a few months, I sent the unit back to Vexilar for repair under warranty. I explained the problem. They sent it back pretty quickly. I charged again overnight and once again the battery level indicator on my phone only showed half charge. I was disappointed to say the least. Nevertheless, I turned the unit on and left it on. In about 3 hours it died. I will not be using it. I now own an anchor. ## Frequently Bought Together - Vexilar SP300 T-Box Smartphone Fish Finder with Portable Case, Black - Eskimo® 43416 Anchor Install Adapter, Shelters, Red - Artist Unknown Vexilar TSA001 Transducer Support Arm for Rod Holder --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/1152043-sp300-t-box-smartphone-fish-finder-with-portable-case-black](https://www.desertcart.vu/products/1152043-sp300-t-box-smartphone-fish-finder-with-portable-case-black) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-02*
