Garmin Striker Cast GPS—Castable Sonar

Garmin Striker Cast GPS | Fishing Wire (thefishingwire.com) 

For the many anglers around the country who fish from shore, piers or docks, it’s always a bit of a mystery how deep the water is within casting range, what structures are on the bottom, and where the fish are in relation to that structure. Without a sonar/GPS screen to tip you off, you’re fishing blind.

Garmin’s Striker Cast GPS puts fish-finding technology into the hands of these anglers, at a very affordable price. It provides quality sonar and GPS on any smart phone.

The whole system is encased in a hard plastic housing about the size of a tennis ball. The unit turns on when it’s immersed in water, and links via Bluetooth to your smart-phone once you download the Striker Cast app. You attach the device to your fishing line, cast it out to the water you want to check and presto, a sonar screen appears on the phone.

The Striker Cast is about the size of a tennis ball. It can transmit to your phone from up to 200 feet away.

The device weighs about 3 ounces, so it’s not something you’re going to throw on your light action spinning rod. And it would be easy to pop your line and lose the Striker if you got a dead-stop backlash on a hard cast. I tied it on with 65 pound test Spider Wire braid on the heavy duty snap swivel, just to be sure—that braid will hoist a couple of concrete blocks, so it’s not going anywhere.

You don’t really cast the Striker—it’s more like lobbing a tennis ball, unless you put it on a 10-foot surf rod. I used a heavy action Shimano Sienna 7-footer and a 4000 size reel that would whip a kingfish, and it was about right.

Manipulating the rod, reel handle and your smart phone all at once is a challenge unless you have three hands. The way I worked it out was to hold the rod in my right hand, the phone in my left and also lightly hold the reel handle. I then rotated rod and reel to retrieve line—it sounds more difficult than it is once you’ve made a few casts.

As with any sonar, the faster the transducer moves, the more the terrain and fish below are compacted, while the slower things move the more they are stretched out. Thus, a foot-long bass going slow under a fixed transducer can look like a 40-pound pike. However, you quickly learn to adjust. The system automatically sets range and gain, or you can adjust both manually at the tap of a virtual scale.

Bottom shows red/yellow, water blue, fish and structure also red if large, yellow if small or scattered. The screen has digital depth and water temperature readouts on the upper left.

The unit also has a very accurate GPS system which allows you to map the area you are graphing. Walk all the way around your favorite pond, casting every 50 feet or so as you go, and it draws a chart of all the water you can reach, complete with depth profiles. You can name and save this, and you can also share it publicly. (I suspect that’s a function not many serious anglers will use!)

The chart was made by repeated casts with the Striker Cast. The opening at the center was where the author walked around a creek, so there’s no graph of that area.

The transducer is not like your boat floating over a fish, which usually flushes anything shallower than 10 feet in most lakes. Fish are not aware of it, and in fact I had a catfish come up and bump it apparently to see how it tasted. So, you can graph an area with a couple casts, spot fish, tie on a lure that gets to their appropriate depth, and hopefully connect.

The Striker Cast would also be very useful for ice fishers—it’s compact, easy to carry, and would give you a quick read of what’s happening at each hole you open.

After saltwater use, you’ll want to rinse the connections thoroughly before hooking it up to the included USB charging wire—corrosion is not your friend. I wished the charging LED was a bit easier to see or had an alternate color when fully charged, but that’s a minor inconvenience. The battery lasts 10 hours with a full charge.

The Garmin Striker Cast GPS goes for about $180, and it’s sized about right for a stocking stuffer. Check it out here: https://buy.garmin.com/en-US/US/p/665274
