Default Is Furuno 588 a CHIRP sonar?

Hi,
Is Furuno 588 a CHIRP sonar?
If not, which Furuno has CHIRP tecnology (cheaper one)?

Thank you

No it's not.

Furuno’s RezBoost Sonar Technology offers unparalleled clarity and target separation that the most well know of competitors can’t compete with. RezBoost is a revolutionary new signal processing technology that Furuno invented which achieves CHIRP-like performance from your traditional 600w or 1kW Transducers. The FCV588 offers up to 8 times the target separation than its predecessor the FCV587.

the 1871 and the 1971 are the "cheap" CHIRP furuno units.

No the FCV588 is not CHIRP. For the cheaper end of CHIRP in the Furuno lineup I would suggest the 1871F or the 1971F

The FCV 588 even though not a CHIRP is a very well respected and widely used stand alone sonar unit.

Thank you,

HoweverGP-1871F is 7" and it is cheaper than the 588 (with no CHIRP technology), and includes GPS and FishFinder (beside posibilities to connect to radar and auto-pilot) .

Does the 588 have more funcionality or something else that justify a higher price? What I lose if I buy the 1871F vs 588, considering fishfinder power and functionality (I already own a 587 fishfinder)?


Also, which one is the 1Kw truthhull CHIRP tranducer for the 1871?

GP units are fantastic, as is the 588. One difference between the units is that the GP units are wide screen aspect ratio and the FCV is a taller screen. It may matter if you like looking at the entire water column in deeper water. However I find that the wide screen of the GP units splits nicely so you can use zoom functions for areas of the water column you are focusing on.

It is tough to beat the deal of the GP units considering they are also a plotter and can connect to their wireless radars.

The advantage of the GP187F is certainly the chart capability.....but C-Map charts are not included so that does increase the price.
And radar is a postive also.
For a 1 kw ... thru hull CHIRP..a B175H , B175HW, B175M, ...or the B175L..flush mounted.
B285M , B285HW..fairing mounts

I think I saw that there is a rebate on charts right now too.

Thank you. OK, but related to fishfinder, is there any advantage buying the 588 over the GP 1871F (same power trabdcuder)?

The newer models, GP-1971F and GP-1871F are geared towards the average joe with minimum settings to adjust and they also support chirp. The new models are more like Simrads and Lowrance in their philosophy, minimum settings to adjust and a simple and user friendly menu, leaving the rest to inherent chirp clarity to compensate for the lack of other adjustments.

Are you sure? I think adjustments are the similar between the units. I dont think you can adjust the pulse length on either unit other than through the Rezboost and Accufish settings, which are the same between the two units while using an approved fixed frequency transducer. (rezboost and accufish are not available with CHIRP transducer on the GP1971) Both units you can adjust the transmit rate, TVG, picture rates, etc.

I stand corrected, this is only possible with the high end modules like FCV-295.
