Garmin Striker Cast, Castable Sonar with GPS, Pair with Mobile Device and Cast from Anywhere, Reel in to Locate and Display Fish on Smartphone or Tablet (010-02246-02)

According to my 16 yo fisherman kid this is “the coolest purchase ever”He loves how this creates maps of whatever body of water he is fishing in very clear detail and shows fish (so a great fish finder)He did say that heavy algae cover can make it more difficult to mapIts relatively compactThe battery life is greatIt’s very easy to use (just upload app on your phone and cast away)It was pricey but such a fun and beneficial purchase that it is worth the $$

This thing is super cool. If you use the right lures, you can cast where it says there's cover or a fish and you'll catch anything you want. The fact that it tells water temp and such is super neat and helpful too.

It works well but loses contact with my phone when its more than 20 feet away. And it only goes up to about 150 feet accurately. If I had anything to improve, it would be to add a fish alarm function. It would be nice if the phone could beep when it sees a fish. If you are not continuously watching the screen you'd never know there was a fish down there. As a result you have to keep the screen on all the time and that drains the phone battery down too fast.

I bought this as a birthday gift for my husband and he absolutely loves it! He fishes from the shores and banks mostly and he uses the fish finder every time. It shows the water temperature, depth, and you can see the fishes on the phone.

Very useful and easy to use. I used it for ice fishing. Awesome.

Pretty neat little device but the app needs some serious rework...Can't speak for the iOS one, I've only tried the Android one.The puny little sliders to manually adjust the depth and gain are absolutely ridiculous. To fine tune the depth you need to adjust a little slider where a slight movement of about 1-2 mm on the screen makes the depth jump from 3 feet to 20 feet. Ridiculous.... You need a slider for coarse adjustments, then "Up" and "Down" buttons for finer adjustments.Ditto for "gain" settings....First of all, if "auto gain" and "auto depth" worked like they should, you wouldn't need to play with these tiny sliders to begin with....GPS position is jumpy and takes a bit of time to eventually stabilize...Quickdraw Contour works pretty good, as long as you have good depth detection and GPS position, of course.Overall rating:Maybe 6 or 7 out of 10. Device itself has potential, but the App itself is baaaaaaaaaad....I hope they fix it soon!This is pretty neat device to have when jumping from hole to hole looking for fish on the ice.... But the imaging quality will never equal what you get with a 'real' sonar. I have a 73sv UHD2 and I'm spoiled. :)

Great product works just as I thought it would

I use this in my float tube. Small, light weight, keeps its battery charge all day. It's reassuring to know that there is something below the surface. But you still have to do the catching. I bought the GPS enabled unit. The lake depth map online sharing feature is slick. I now know where the "Honey Holes" are.
