Sounder for OK Prowler 4.3 Ultra

[damos]

Recently I upgraded my yak from a Tarpon 100 to a second hand OK Prowler Ultra 4.3. I have had it for a month or so and am starting to look into a sounder for it but have a few questions that I'm hoping someone may have answers to. 

1. I want to make use of the transducer scupper hole but do I have to use a Humminbird model? Do Garmin transducers fit?
2. Do I need to purchase the transducer kit? I have tried locating one but can't seem to find one online in Aus
3. Do you need to drill a hole to feed the cable for the battery?

Would love to hear what other OK owners have done. Previously on the Tarpon I had an internal wet mount which I had to add water to each session. Found it pretty annoying hence trying to make use of the OK preset scupper.

1. Designed to fit different brand trannys 

2. Ocean Kayak Transducer boot kit or fabricate your own ?

3. Hole is predrilled, sits under tackle box, black grommet.

Cheers thanks Lungfai. So with the predrilled hole under the tackle box, do you mean within the centre hatch?

Ah sorry, didn't read the ultra bit ?, don't think the ultra has the predrilled, you'll need to drill your own and use a grommet to seal or better yet a ip68 rated nylon cable gland.

Ah cool thought I was missing something. Cheers.
