Elite 5x chirp transducer replacement

Just like the title says- can anyone point me towards a replacement transducer for a Lowrance elite 5x chirp? I got gifted a head unit, but have never had a FF on the yak so I'm lost as far as what I should be looking for. I mostly fish kelp down to 150ft and mostly want to see structure on the bottom, but marking fish would be cool too.

Does such a thing exist sub $100 or should I just get a Striker 4 new?

dang..I just dumped my old transducer for that same setup.

Is this what you need?

Here is the link to the selector tool page to help figure out which transducer you need. Once you know which one you should be able to find one for sale.

Appreciate it and the link (I've looked at before) but I'm a little lost as to what exactly I would need, if that makes sense. For instance, is this Amazon one much worse?

That one has the wrong connector for your Elite 5x.  You need the 9-pin connector for your fish finder.

What has you lost on what you need?  Is it deciding between the different transducer frequencies?  Something else?

ahhh...this one.  no I don't remember the Khtz..  I looked in the edisposal bin in garage and it isn't there.  wife emptied it already. 

My Hook 5 takes a 7 pin plug. Look at yours, how many pin holes are on the sonar connector? It looks like the Lowrance site shows one for an elite with chirp. Google the part or model # to see if you can find it cheaper elsewhere.

I just checked and it's an Elite 5 chirp (no x) and is 7 pin. I'm mostly lost on the frequencies and their importance as well as whether a given transducer will work with chirp (or is it so commonplace nowadays that they all will)?

My last question was transducer type (skimmer vs bullet vs the super long ones). This will all help in deciding if it's worth buying a new transducer vs buying a whole new unit like the Striker.

I really appreciate everyone's help and input on this! Makes me miss leaving norcal for the sunny south.

The frequencies determine how the transducer performs at various depths and boat speeds.  Here's a snippet from West Marine:

Fishfinders operate using a single frequency transducer, dual frequencies, multiple frequencies or a broadband CHIRP system. In general, higher frequencies give the finest detail resolution, the least background noise on your screen and the best view from a fast-moving boat, but don’t penetrate as deeply as lower frequencies. Shallow-water inland anglers generally choose higher frequencies of 200kHz, 400kHz or 800kHz. For maximum depth, use lower frequencies. We recommend 200kHz or higher (up to 800kHz) for water depths up to 200' and 80kHz or 50kHz for deeper waters.

CHIRP expands on this a bit...

The newest style of broadband fishfinders, commonly called by the acronym CHIRP (Compressed High Intensity Radar Pulse) don’t transmit on just one or two frequencies. Instead of transmitting only 200 or 50kHz, for example, CHIRPing devices transmit a signal that sweeps linearly upward (from 40 to 75kHz, 130 to 210kHz, or other frequency ranges).

CHIRP fishfinders transmit less peak power than a conventional fishfinder, but their wide-band, frequency modulated pulses (130-210kHz, for example) can be very long in duration and put 10-50 times more energy into the water. Using digital pattern matching and signal processing, CHIRP devices achieve unprecedented resolution and target detection. Your ability to resolve individual fish, or separate fish from bottom structure, is now a matter of inches, instead of several feet with traditional fishfinders. See individual fish in groups, instead of a single mass.

Depth ranges of 10,000 feet are standard with these broadband devices, which include sounders from all of the major brands. Some of these sounders feature dual-transceivers that allow for simultaneous and independent dual transducer operation, which allows complete customization, as you can CHIRP or dial each transducer into specific frequencies.

CHIRP devices can transmit simultaneously on high and low frequencies. The lower frequency gives greater depth penetration, and it requires less power than a higher frequency signal so it generates less noise. The result is a “whisper into the water” that locates the fish without disturbing them. The higher frequency signal gives even finer detail at shallow to mid-water depths.

So, if CHIRP is important to you, then you want to ensure you get a CHIRP transducer.

As for mount... you will likely want a transom mount.  Those are the ones that are easiest to mount to kayak-specific mounting kits or to glue inside the hull so it will sound through the hull.

7-pin is the legacy connector for Lowrance, so you could buy a 9-pin transducer and then buy a converter cable.  However, 7-pin transducers are still available.  Here's one I found that seems to meet your requirements: https://www.thegpsstore.com/Marine-Electronics/Transducers/Lowrance-HST-WSU-200khz-Transom-Mount-Transducer

Think of it this way. The transducer emits a signal in a cone shape. Lower frequencies like 70Khz will deliver a wider cone at depth. Higher frequencies like 270Khz produce a narrower cone but work much better in deep water. A wider cone will reach out further allowing you to see fish further away from the transducer but loses sensitivity at depth. A narrower cone will only see a small patch that's directly under the transducer but it will have greater resolution and sensitivity at depth. Example at 50' of water low frequency will be 50' wide at the bottom of the cone and a higher frequency will be 25' wide. What frequency to use all depends on what type of fishing and what depth you want to look at. Most Fish finders have a simulation mode. try that and you'll see what I'm talking about. Also there are a ton of hoe to videos on UTube out there about setting one up.

Thank you both for all of the clear info. Seriously the best read I've done on it, and a lot clearer than the Lowrance website.
