Garmin Striker Cast with GPS suits anglers who want custom contour maps, while Deeper PRO+ 2 offers a choice of 3 sonar beams and a stated range up to 330 ft. The standard Garmin Striker Cast keeps the 2-D and ice flasher modes, but does not state built-in GPS.
All 3 are castable sonar devices that connect to a mobile device. Garmin uses the free STRIKER Cast app and streams up to 200 ft; Deeper PRO+ 2 uses its own Wi-Fi connection and states accuracy up to 330 ft.
The best fit depends on whether you value Garmin mapping, Deeper's beam choices or a simpler Garmin setup. For more options in this style, see our guide to portable fish finders for kayaks.
Garmin Striker Cast vs Deeper: which should you choose?
Choose the Garmin Striker Cast with GPS to make custom maps; choose Deeper PRO+ 2 to pick a beam width for the scan. Both can map fishing spots, but the mapping workflows differ.
Garmin's GPS model makes custom maps with 1 ft contours using Quickdraw Contours software. It also gives you access to the Quickdraw Community to download maps.
Deeper PRO+ 2 uses built-in GPS to create bathymetric maps from shore, a dock or bank, and saves maps in the Fish Deeper app. Its wide, mid and narrow beams let you choose how broadly or narrowly to scan.
The regular Striker Cast is a third option if you don't need built-in GPS. It can download maps with 1 ft contours from Garmin Quickdraw Community, and includes traditional 2-D and ice flasher modes.
Garmin Striker Cast vs Deeper range
Deeper states accuracy up to 330 ft, compared with Garmin's wireless streaming range of up to 200 ft. Treat these as stated capabilities, since connection conditions can affect practical use.
Deeper's connection is its own Wi-Fi. Garmin pairs with a compatible Apple or Android phone or tablet through the STRIKER Cast app.
A longer stated range can matter when fishing from a bank or dock, but it doesn't tell you how well a connection will hold in your location. Consider where you'll cast, how you'll retrieve the device, and whether your phone will stay within a comfortable viewing distance.
How do their sonar features compare?
Deeper PRO+ 2 gives you 3 beam widths; Garmin gives you traditional 2-D sonar and an ice flasher mode. Pick based on the kind of sonar view you expect to use.
Deeper's wide beam covers larger areas, while its mid and narrow options help focus on a smaller spot. Deeper also states target separation figures of 0.4 in for its narrow beam and 1 in for wide and mid beams.
Both Garmin versions offer traditional 2-D sonar and an ice fishing flasher mode. The Garmin GPS model's information also describes use below ice, along with shallow and deep water.

Which one makes mapping easier?
Garmin suits anglers who want to build custom 1 ft contour maps with Quickdraw; Deeper suits those who want maps saved in Fish Deeper. Both offer GPS mapping, but the apps and map sources differ.
With Striker Cast with GPS, the device's built-in GPS supports custom fishing maps through Quickdraw Contours. You can also download maps from the Garmin Quickdraw Community.
Deeper PRO+ 2 makes bathymetric maps from shore, dock or bank with built-in GPS and saves them in the Fish Deeper app. Its mapping can suit someone who fishes from shore and wants saved maps without installing a boat-mounted unit.
The standard Garmin Striker Cast is different: it can download maps with 1 ft contours from the Quickdraw Community, but its features do not state custom mapping with built-in GPS. If marking and revisiting locations is central to your choice, compare the best fish finders with GPS for other device types.
How do the apps and setup compare?
Garmin pairs with the free STRIKER Cast app, while Deeper connects by its own Wi-Fi and stores maps in Fish Deeper. In either case, a compatible phone or tablet is part of the fishing setup.
Garmin describes quick setup: download the app, pair the mobile device and sonar, then start fishing. Its app supports Apple and Android devices.
Deeper's PRO+ 2 information calls out its own Wi-Fi connection and the Fish Deeper app for saved maps. The stated features don't give a setup time, so plan to pair and check the app before you reach the water.
Think about your phone's charge, screen visibility and how you'll keep it secure near water. The sonar device doesn't replace the phone or tablet used to view its readings.
What about battery life and care?
Garmin states 10+ hours of battery life for both Striker Cast models; no battery runtime figure is available here for Deeper PRO+ 2. If you fish long sessions, that published Garmin figure may be useful for planning, though usage can change runtime.
Both Garmin devices use an internal USB-rechargeable battery and conserve power by turning on when floating and turning off when removed. The GPS version is rated IPX6 and IPX7 water-resistant, and Garmin describes the body as rugged and lightweight.
Deeper's information describes a wireless, lightweight design but doesn't give a battery runtime or water-resistance rating. Keep the device, phone and charging gear according to each maker's instructions.
Which castable sonar fits kayak or shore fishing?
Deeper PRO+ 2 has explicit mapping from shore, dock or bank; Garmin's GPS model can create custom maps, while both Garmin units can cast from shore, dock or watercraft. A kayak may place the phone and sonar close together, so mapping and beam preferences can matter more than range.
For kayak fishing, consider where the sonar will travel and how you will watch the display while paddling. Our guide to kayak fish finder mounting covers ways to secure a separate display device.
Shore anglers may prefer Deeper's map creation from the bank and its beam choices. If you mostly want to inspect fish and structure from the edge, plan where the phone will sit while you retrieve the sonar.
Garmin Striker Cast vs Deeper: the decision
Pick Garmin Striker Cast with GPS for custom Quickdraw maps and ice flasher mode; pick Deeper PRO+ 2 for beam choice, bank mapping and its longer stated range. The standard Striker Cast fits if Garmin's sonar modes matter more than onboard GPS.
The GPS-enabled Garmin is the clearest match for anglers building their own contour maps. Deeper offers the widest stated scan choices and a longer stated reach, while the base Garmin keeps setup focused on 2-D and flasher sonar.
