What’s new on the sonar market? Many of you have heard the new buzz word CHIRP. What is it, how does it work and what will it do for me and my fishing?

CHIRP technology was originally developed for radars. The term stands for” Compressed High Impact Radar Pulse.” Its development dates back to classified work and use during WWII era. The technique became declassified around 1960 so its use became widespread including application in commercial sounders. The needs of the two domains are very similar as radars and fish finders both care about discriminating between targets and having good distance performance.

CHIRP technology allows a sounder to sharply reduce its effective pulse length and with it, gain much higher resolution with respect to determining the position of a target. That gives it resolution down to sub inches vs. feet for traditional sonars. Importantly, the range resolution does not depend on pulse length anymore allowing it to get more power into the water. More power means deeper penetration and better quality target returns. The improvements here are very significant.

Lowrance has taken CHIRP technology down a whole new road. The SonarHub module can take a standard Lowrance transducer and produce a CHIRP pulse from it. This pulse gives greater target separation and definition even on small targets.

I have been testing SonarHub for the past few months on a standard transducer and have found the target separation is excellent as is the definition of the fish it displays. You will see clear defined fish aches. Even the smallest targets produce great returns.

Now you can make your Gen2 and Gen2 Touch sonars “CHIRP” by adding a Lowrance SonarHub to your system. The module will even allow your standard 50/200 transducer to CHIRP.

The SonarHub module is the same size as a standard Lowrance NEP-2 Expansion Port, uses the same power plug and has three extra connection ports for additional Ethernet connections. It also has a port for StructureScan to plug into. If you currently have a StructureScan box you can replace it with a SonarHub and use the same connections.

You can order the SonarHub as just the SonarHub Module and use with you standard transducer or with an additional Airmar TM150M single-channel CHIRP transducer.

CHIRP is the way ahead in sonar development and when you see it in operation on a Lowrance sonar you will agree there is nothing that will compare to it.
