So far the frequencies that have been posted for SI are:
455 CHIRP
420-520
790-850
1200 CHIRP
1150-1275
1175-1275

Why wouldn't 800 be an option?
It is. It is now showing in the specs
Yep for the 12 - 1200KHz for the 9 & 10 isn't listed in specs section but IS up top.Quote:

This has been reported ... (and the missing "DI" icon in the 9 G2N specs) ...Quote:

Wish I would of known something about this since I just bought two Helix 10 SI units and 360 a month ago......
core series has always been updated on a semi annual schedule. if you watch for the clues you can tell when something is coming. maybe someone should start a buyers guide like they do for apple products

Is the extra detail and range going to really help? Seems like the added benefits wouldn't be fully realized without an exceptionally large screen to really show it all.
That, and I just should of started an account here earlier and asked all you smart guys about them.... Mega Imaging does look great but I'm still amazed at my new Helix10s considering I just came from Lowrance Elite 5x DSI units.Quote:

From the information I've seen, Mega SI is supposed to extend to 400 ft. per side using only 455 khz at that range, while the true chirp SI of 420-520 khz is only 240 ft. per side. That doesn't make sense!
MEGA is the 1200 kHz (or 1.2 mKz) and it has the shortest range capability.Quote:

Mega only goes out 125' on both sides, 455 will go out to 400' each side
Specs for the Mega units have been cleaned up on the HB website ...

This is for HELIX DI G2N 9, 10, and 12 ...:

HELIX 9 SI G2N still doesn't show the "DI" feature icon ... but that's a small oversight I'm sure ...
Rickie
Product manuals for 9, 10, and 12 G2N now on the HB website ...

All the same manual, except the H12MSI link incorrectly names the PDF an ASPX file...LOL
Will this ever become a upgrade for 1100 series
