Lowrance, Simrad and B&G are releasing their own Halo20 and Halo20+ pulse Compression >Radar models, arriving in-store early December. NOW IN STOCK.

They follow in the footsteps of Halo24, which was released last year in 2018.

But how are Halo20 and 20+ different to 3G and 4G Radars?

Pulse Compression technology

Where 3G and 4G >Radar are >FMCW radars, Halo20 and Halo20+ utilise pulse compression technology.

Pulse compression allows a >Radar to use a long pulse to achieve a large radiated energy, but with the Range Resolution of a short pulse of wide bandwidth.

Meanwhile, traditional >Broadband (FMCW) >Radar sends a signal where the Frequency is continually changed in a repeatable pattern that's modulated over time.

Halo20 vs. 3G

Halo20 is a good replacement for 3G >Radar. It is lighter and less bulky, much more slim-lined than 3G or four G radars, making Halo20 a much more compact solution for installation onboard smaller boats.

Halo20 also has the same Antenna rotation speed as 3G >Radar at 24rpm.

Halo20 and 20+ vs. Halo24?

The Halo radars all use pulse compression technology, but at 20” diameter Halo20 and Halo20+ are smaller and more compact than Halo24 (24”). They offer a more affordable solution for sailors than the Halo24, yet still provide high quality >Radar imaging and performance.

Halo20+ and Halo24 both boast Dual Range support, and a super fast Antenna rotation speed of up to 60rpm. The effect of high rotation speed is almost the same as continuous 360 view, as opposed to the sweeped view of a traditional >Radar. 360 view provides extra safety and much better collision avoidance.

Halo24 covers a slightly larger Range – up to 48nm, where Halo20+ covers up to 36nm, and Halo20 covers 24nm.

Bird Mode?

Halo20+ and Halo24 have Bird Mode.

VelocityTrack

Halo20+ and Halo24 feature VelocityTrack Doppler technology, which helps improve your situational awareness by colour coding information for a real time view of whether something is moving towards you or away with no limits on screen, so no need to manually select targets.

Beamwidth & Target Separation

Halo20 and 20+ have a slightly wider beamwidth (4.9° H x 25° V) than Halo24 (3.9° H x 22° V) – and even wider again than 3G or four G >Radar (2.6° H x 25° V).

So if you're looking to upgrade your >Radar set-up, Halo20 and 20+ are well worth a look and will make a great addition to your Boat.

They will be arriving here in-store early December – so Stay tuned!
