Its bloody frustrating owning a kayak sometimes.
 
Looking into getting a new FF for the winter to rassemble the P13 with a color unit the missus has kinda given me the OK to get one soon to install over winter! Been having a look at the high end models from Humminbird, Lowrance, Furuno and most impressivly for me it is the Raymarine AD50. Its insane..
I wanna upgrade my FF to give me more confidence going further offshore I want to see as much as possible if I am heading out on long trip and not have my electronics struggle finding fish or stucture in deeper waters.
 
The Raymarine is possibly the one I want to get but the transducer (Aimar model) is frikken huge and weighs a house brick, how the hell do you install one on a P13 or any other yak TBH! You can't just put them inside the hull either even though the unit puts out 500 watts of grunt its digital signal advantage would be lost if you did this. They have to be transom mounted ideally but the back underside fin on the yak doesn't really help you out much does it! I have been brainstorming all afternoon on a bracketing system (I know you did one MentalLOL, how is that going??) without affecting the kayak performance? And ideally not Ali or any other metal I would prefer plastic. Anyone had any plastic welding done on their yak in that area as I was thinking of taking mine to shop to get done.
 
Any thoughts fella's? Cheers.Thumbs Up

I like Raymarine kit it's good stuff, or at least when it was made in the UK...

BUT the A50D is ONLY IPx6...

I think it means you could probably sneeze on it without ****ing it up but anything beyond that would probably break it.

IPX 7 means you can submerge it in water for half an hour and it will survive.
IPX 8 means it's actually waterproof and can remain underwater indefinitely.

IPx6 is fine for a boat, may be it'll get a bit of spray over the bow, or may be even get rained on... if your fishfinder is 1m under the water on a boat you probably have more to worry about then you electronics...

No worries with the transom mounting EXCEPT if you angle it to get it on the roof you end up with the transducer on the floor - not a problem as such but you have to remember it's there... Yes if you want it permanent then mount a wedge on the transom, I did toy with this idea but a) wanted it removable when I get a new kayak and b) needed something quick.

For plastic welding throw the kayak on the roof and go see Johnsons in Silverdale they have a couple of welders, and plenty of plastic...

Wondaboy used to have a raymarine - installed in hull i think

Has changed to - i think a Lowrance?

Anyhow pm him if you want to know why he changed

Cheers

The AD50 is used by some of the Jetski lads so it must get a hammering on thew water. IPX6 is able to withstand serious heavy seas apparently, I have no plans on going upside or overboard and will avoid all chances of that happening as you know Mental i.e. Toots!LOL But it can happen I know....
 
There are Raymarine IPX7 units available too the DS fishfinder only series which are discontinued but still available using the same HD technology. These are obviously not as crystal as the 640x480 pixel AD units but still bloody good units but still have the same transducer problem of being huge.
 
its a big decision it has to be right for the $$$ I will be spending!
Is anyone running the Lowrance HDS or Furuno models at all??

A Jetski doesn't get submerged either... and your kayak WILL be upside down at some point - that's not a doom and gloom thing - it's a fact...

My kayak has been upside down three times that I can remember in the last 12 months - NONE of them were planned... Last one was about two weeks ago on what was a pretty flat day - just leaned out a little too far to try and flick my line off my rudder and... Cost anything that wasn't IPx7 (my "rugged" phone) and everything that wasn't tied on (two $2 shop knives and a towel)

Been yakking for over 7 years and never tipped one yet even jumping in my ol scrambler XT off the stones in horrible swellsWink You watch I will go head first in in the morning now i said thatLOL

Its a point though mate I know over 2 k on a FF thats not IPX7 rated is a steep risk maybe to far.
I don't think there is that many true IPX7 rated FF models on the market though and a lot of manufacturers don't state there trueratings, Humminbirds for example?? Lowrance too in fact Raymarine are the only ones that really state true IPX ratings at the point of retail.

Ive got a supposedly ipx7 rated garmin ff 90 and Ive had it apart after its died during dunkings. It has no rubber gaskets between the front and back of the unit, just plastic to plastic. It shows signs of moisture, fogging behind the screen when Ive been hit hard by a big wave or turtled. Thats why Ive taken to stowing it. Yet my etrex gps has been perfect no problems at all.

yep it always gets you when you least expect it.

when we went out on Thursday the sea was flat, not much surf - didn't even pack my rods away

coming back in I miss judged a wave. I usually like to get on the back of one and ride it in rather than surf one in, however I haven't had too much trouble surfing the Profish in. Any hows ended up surfing in when another wave bounced back off the cliff and came running back along the wave I was surfing in - yep it ended in tears. Nothing broken, nothing lost, bruised pride.
1st turtle in the Profish.Cry

never tipped out of a yak at seaThumbs Up only in the surf

Never had a Lowrance or Egale wrecked from being dunked - went through 3 screens on the humming bird in 12 months

muppet, if you don't have the rudder installed then maybe a bracket that fits onto that slot with a kick up action if you strick. In the past i've have side mounted brackets and from my experience they get in the road, either with paddle stroke or lines etc. I've seen other p13's with the transducer mounted where the rudder mount is. Might come out of the water in large chop and get some cavation effect but probably the best postion (outside locating it in the hull). Mounting it outside also brings back into play the water temp readings as ones inside don't ready correct. If you at all interested in water temps.

I have considored that JB, had a looksy at some units this arvo, spoke with the electronic experts its interesting what they had to say on the Lowrance HDS. They were advocating putting the transducer inside the hull but I wasn't buying it. Tough choice coming soon.

I think if it was me I would be going for the inside hull install. I just don't think there is location as good as in the middle of the hull. If these kayak manufactures made a good sized scubber pocket and didn't just cater off there parent companies product you would have no worries.....

Yes that is a good point, and probably my main reason for replacing my Elite with an Ultra... I'm used to "fishing my feet" i.e. seeing fish on the fishfinder under my feet and then dropping a bait down to it, and seeing my bait going down on the transducer, with my transducer now mounted in the stren you can't fish like this at all, and you don't see fish till you passed over them so you end up fishing behind you... or drifting backwards and trying to get the bait in the right place... just not the same as having the transducer in the center...

If you troll through this forum you will not find too many water proofing complaints about Lawrence FFs, which gives me more peace of mind than any company paper ratings.    I am just one of many users who can lay claim to that fact.    BTW you don't have to dunk a FF in a turtle to get moisture in,  air exchange will suck in moist air, which then condensates behind the screen and quietly corrodes your electronics inside.    
 
If you go after game fish such as tuna it is pretty vital to know the water temperature.  You can only get an accurate reading with an outside transducer mounting.

Fair point Rainbow more research on the HDS series has them manufactured as IPX7 and my Lowrance X52 is working fine again since I changed the fuse which had completly corroded out.
I know Lowrance is extremly good but have also heard some stories outta the States saying the HDS series is not as good as the older models. But at least you get a 2 year warranty....
 
The transducer location on a kayak IMO is not that important as long as the transducer stays in the water! Which is the problem with putting a bracket on the back of the yak in choppy seas, it would just be the same as a boat install. Remember your beam is a circle (stating the obvious) not a straight line it will just means the front of the beam is a couple of metres behind what it would be thats all.

Speaking from real experience you WILL notice the difference - but then again if you don't currently use your fishfinder for targeting fish then no it probably won't matter to you - I got very used to being able to target a fish on the bottom and dropping my bait in the water, watching it drop, and seeing the fish come up to hit it... Moving the transducer 2m back makes this very difficult as you are now fishing two meters behind you and rather than striking at the fish in a vertical movement you are pulling it way at an angle...

Anyway that's my observations, I'll be very keen to hear your feedback when you've fitted yours.

Yep also heard mixed opinions about the HDS stuff but to be honest they are probably biased as I heard most of them on the HB SideImaging forums LOL Actually what is putting you off the Humminbird?

Don't get me wrong Mental I WANT my transducer in the scupper hole but we know that one size doesn't fit all which is the point of my article, anyways is yours not working as well as you hoped?? You have far more knowledge on that than me mate and was hoping for your opinion, would I be totally wasting my time putting a transducer there?? Maybe we should discuss over a beerThumbs Up
 
I watch my sofbait get snaffled by snapper all the time especially in the channel its hilarious watching those thin black lines come up to meet that fuzzy little line on the way downLOL But I can't hunt down targets in deeper water which is the reason for the upgrade.
 
Humminbird is still in my thoughts as far as my options go, it will be a high model so hopefully I have no water issues if I do go Humminbird but only have a 1 year warranty. I don't want side imaging by the way just power and a clearer picture of whats a happening beneath the wavesWink

Ok...

Cons:
1. Transom mount means it's very hard to drop you bait on top of fish
2. External mount means you are forever scared of catching it on a rock/reef/beach and scratching it or snapping off the transducer
3. It must add some drag to your kayak - although probably not noticeable
4. In rough water it "pops" out of the water loosing signal

Pros
1. No hull interference
2. Temp works - but of course only the temp if the top two inches of the water and the transducer will also get heated by the sun - not sure who much this will effect the reading need to go out there with a thermometer one day...

Yep side imaging is a novelty and I've only used it a handful of times to identify so fishy looking structure say 50m to the left. My deepest fishing so far with my Humminbird is 50m and it was still picking out individual fish on the bottom (although sideimaging is useless at this depth, it's only meant for the shallow stuff) - but how deep is deep?

Touch wood I'e had no issues with my 798CI, it's been smashed by plenty of waves over the bow, turtled once, and I'm not sure how others clean their electronics but at the end of the day I fill the kitchen sink with warm water and throw my electronics in and give them a swirl around to rinse all the salt water off/out...

I had an external mount on the F n D. Set it up on a fold up bracket so that you could lift it out of the water when paddling. When it was down, it was like dragging a couple of lures.

I would always install it externally if possible.

I just have a 50dsx and they are ok for structure up to 75m - in saying that I haven't used a high end FF so I don't know what I'm not seeingErmm

I would be keen to get a high end ff with chart plotter, but would have the same mounting problems as you Muppet


The solution to any problem - work, money, love, whatever - is to go fishing - the worse the problem the longer the fishing trip should be.
