Castable sonars changed the way anglers can investigate a lake.
The Deeper CHIRP+ 2 takes that concept and gives shore anglers access to depth information, underwater structure and potentially fish indications without requiring a boat.
The real value for carp fishing isn’t seeing a little fish symbol on your phone.
It’s building a better understanding of the lake.
Depth changes, shelves, bars and weed can all influence where carp spend time.
On unfamiliar venues, being able to map those features can save a huge amount of exploratory casting with a marker lead.
There are limitations.
Sonar doesn’t magically tell you that a particular mark is a 42lb mirror waiting for your rig.
Interpreting information correctly is still important.
And on very pressured waters, repeatedly casting a sonar around can disturb fish just like hammering the lake with a marker lead.
I’d therefore use one primarily for learning the water rather than obsessively scanning during every session.
For anglers who visit France, fish large reservoirs or regularly tackle unfamiliar waters, that’s where devices like the CHIRP+ 2 really start making sense.
Do you use a Deeper for carp fishing or prefer the traditional marker float?
