yes bottom lock capable but says sonar zoom display only. Not quite sure what that means. Yes the P66 I need a 9pin plug but struggling to find that for sale. Marine deals has everything else but… I’ll keep on it. 

Krow - you will see a difference - by some factors. Yes the full screen still shows you stuff but you get 2-3 x the detail on BL. Stuff you could miss on full screen you will clearly see on BL. If the screen is full of fish, maybe not much difference. But if you are scratching around and picking up small numbers or the odd fish, BL will find them.

If the weather gods are willing I may be able to show you the difference tomorrow. The screen on my Garmin isn't flash, but I am hoping for some bottom fishing between 175-200m.

always nervous buying larger ticket items overseas. If it’s wrong or issue your on your own. But I have successfully in the past…I got told to contact BLA NZ as they import hummingbird and Airmar to double check 9 pin plug is the right one and compatibility. Unfortunately sales guy not got back to me yet… 

yes indeed Alan L. I’m glad I tracked down the BLA rep and didn’t just buy the 9 pin plug. Apparently hummingbird has 2 9pin plug options a helix and solex phew… the helix is the updated head unit from mine so has the same plug. Fish city Albany said they had a 9pin when I did a ring around yesterday so will check which it is. If not it will have to be purchased overseas with a delivery up to early December.

ok back to drawing board. I asked fish city to try the P66 plug on the display hummingbird s and it wouldn’t fit helix or solex…. It’s a strange plug on the hummingbird it’s multi connections in a row on one plug. Google say bay marine lectrical department have some nouse so waiting on a return call from them…the latest hummingbird helix comes with a 1kw P66 so it should be possible….

Hmm, just tried the Airmar site. They don't list Humminbird. Odd.

wow this has become a full on global research mission. What I have found thus far. Hummingbird NZ (BLA) don’t have technical knowledge on what plug is required it seems they say a helix or solix. I called hummingbird Australia (BLA) they were lost but came up with an option. They have said get a standard P66 then buy a mix and match connection that is made for hummingbird and gave me the product number. I researched further online and found there are two P66 cables for hummingbird helix and the one they gave me was for a 1KW 9pin plug. But my head unit only goes to 600w so dug further and found a 600w (in the Netherlands) that requires a 5 pin plug which is the first I have heard of a 5pin plug after talking to all the dealers techs, suppliers etc. I’m thinking if there is a 5 pin mix and match plug there must be a hummingbird 600w standard, p66 as they seem to have many plugs on their transducer units. I’ll keep researching. I am becoming the expert in Austrilasia on this topic. I maybe the first to do this in the Southern Hemisphere 🧐😁

Yep - it is not simple sometimes - I am going thru the same thing trying to mix/match my 50/200 with the Echomap series. Waiting for a guy to tell me about the pin compatibility on the back of the Echomap.
