Nolongeramember Posted November 21, 2007 Share Posted November 21, 2007 Im buying a new sounder and want to make sure I have enough power to get good readings out wide... What is the approximate depth around Browns Mountain, and the various reefs etc off Sydney? And just out of curiosity, how deep is it after the Continental Shelf, and how big is the drop? Thanks guys... Link to comment Share on other sites More sharing options...

Thanks guys... Hi Roylo..... ask and look around first with other boats what sounder's and transducer's they are running and it will quickly come clear to you what does the job... the depth at the top of the mountain is around 1,270 ft dropping down to around 1,500-1,600 ft on the fringe's so that amount's to around half the depth deeper drop than the continental shelf at 600ft ( 100fths) sorry about the feet for brown's...i will let some of the other guy's give the depth's of some of the other reef's......in regards to the drop?.... i take that to be after crossing over the continental shelf and when you do after an initial steady drop to approx 120 fths it is just a gradual progressive drop from there onwards......this of cause can vary greatly from what part of the coast line you do it at..... good luck on your choice of sounder.....

Red Posted November 21, 2007 Share Posted November 21, 2007 All good advice. Buy the best you can afford, preferably 1kw as a minimum. Tabsy, i always thought the shelf line was 100 fathoms Good luck at the Whitesands mate. What are you targetting? Regards Red Link to comment Share on other sites More sharing options...
Red Posted November 21, 2007 Share Posted November 21, 2007 I dont know, I was taught that 200 fathoms was the true nautical shelf line, but I could be wrong..... You're probably right mate. You often here south coast fishos talk about the 2nd drop etc I'm sure you'll do well in the comp. You just got to keep an eye on those "Reel Quick" lads Regards Red Link to comment Share on other sites More sharing options...
Nolongeramember Posted November 21, 2007 Author Share Posted November 21, 2007 Ok thanks for he replys. Sounds like the deepest water Im ever likely to come across in a trailer boat off sydney is at Browns at approx 450m. Is that right? Just on the sounders, Ill ask here while Im at it. What depths approximately does your 200KHz frequency run out of steam and you start to use 50KHz. From what I can gather 200KHz gives a better reading so you would persist with this until you have to swap to 50KHz. Link to comment Share on other sites More sharing options...

Hi roylo just to clarify things a tad.....you will come across greater depths of water than browns...... but most likely browns will be the deepest depth of water you will most likely attempt to fish...having a sounder that will punch to that depth is an advantage obviously if you are going to be fishing the mountain...200khz against 50 khz.again depends on what set up you are running if it were to read better on one or the other ....... then you would just switch over accordingly i myself read it on 200khz easily.....co-incindently when i myself fish out way over the shelf most times i would not be reading the bottom that would be a waste of time for me..... but have it reading the top coloumn 40 fathoms of water endevouring to locate bait and this is were the plotter comes in to its own by using the contour lines as a guide........you will find that when refering to the shelf we are talking 100 fathoms the second drop off being 1,000 fathoms.......places like bermagui for example are easily reachable but out of sydney......only for the big fellas.......hope that is a bit more insight for you.....

netic Posted November 21, 2007 Share Posted November 21, 2007 Roylo.....off the mountain it does get as deep as 600 metres......450 metres will be right on the mountain Link to comment Share on other sites More sharing options...
