Hi Keith

The Piranha range from Hummingbird is, as said above, very good value for money and are completely portable.

I have, however, heard varying reports about their effectiveness.

My Fishfinder - which you saw the effectivenes of when finding our way back to the locks - is the Garmin 160 Blue. It is dual frequency an very effective. The only difference form the 100 is the screen size.

As Alan has rightly said, they are of little use at speed, but in restricted waters your speed would be such that they are effective.

I would disagree slightly with the argument that on the transom they are of little use. If monitored closely they do show the pattern of the sea bed, and you can anticipate problems. Yes, a forward facing transducer would be better, but at several times the cost.

Another thing to consider is if you need the'Blue' version of the 100 - this is a seagoing version - you may be able to use the standard 100, which is even less money if you are minaly cruising fresh water.

Al in all the Garmin range are ver good - and the customer service they offer is also excellent.

More decisions to make!

Eagle also do a portable version designed for inflatables, the sounder fits on top of the battery unit in a water proof case. Eagle (same factory as Lowrance) are also very rugged, wish I could say the same about some of the other bits I have had.

Echo sounders should work at speed certainly 20 knots, which is great for searching or wrecks as you can cover a big area with a couple of dive boats. You can use them through the hull if the sounder is reasonably powerful and still get a good picture. The 'well' at the back of some ribs is great for this so long as it fixed to the inside of the hull. The instructions say use epoxy resin but mastic gives good results so long as care is taken to ensure there are no voids or bubbles.

But the greatest advantage to an echo sounder is they stop ppl running aground and damaging props when they see how shallow its getting, they really are worth there weight in gold

It gets better and better.

Pete, the Hummingbird would certainly fit the bill. It looks good, but could be expensive on batteries (8 x AA), however it would be simple to fit. It is certainly a top contender. Has any one got one of these?

Graeme, I was looking at the Garmin 100 'Blue' as most times Quicksilver is out in salt water. Although in Cardiff we seemed to be in slurry most of the time! As you mentioned it certainly did help us to get back through the barrage. We were able to see when the sea bed was rising and falling. I think that without it we would have had to cruise around outside the bay for a couple of hours untill the tide came in again.

Hmm, took a while to find and still can't locate the Eagle / Lowrance site but this is what I was looking for as the solution.

On our NRA RIB we had an older version of the 3D Hummingbird This scans accross the back of the boat giving you depth to the left and right of your current position, and as you move through the water draws a "3D" image - this must be good for finding wrecks!

Humminbird Price

Have not used this actual model, but the quality of the NS25 'bottom' readout is very good, I have it sikaflexed to the engine well and it does fine for me, gives accurate depth, at speeds of around 25knots, and at slow speeds fine.. none of this drill through the hull stuff..would recommend it to anyone . Battery prices.. is not expensive as it is re-chargable.
Will email you aprice in the next couple of days to temp you..

Pete

Hi

Just checking before going off to work. Check out the 3d Hummingbird page on Jools posting, then play with the 3d demo. Great fun.

More research in depth (pun intended) after work!

I had the 3D sounder on my last RIB and it was very good. I you cannot wait till Xmas then you could get a bargin either new/second hand at Beaulieu on the 28th I would think that your outboard has an output to charge a battrey and this can then be used for lots of other things (hand held light, the fridge for the cold drinks etc.) If you need a hand let me know.

Hey I must admit that I thought GED'd posting about an underwater camera on the front of the boat was a joke, BUT, take a look here:

http://www.seaviewer.com/fishing-vid...der-tackle.htm

Anyway, having looked around a bit I am leaning towards the Piranha portable at the moment. It seems very easy to use and install. I've yet to find a uk dealer though (website). I'll keep searching the web but if in the meantime anyone knows of a dealer selling them in the uk, please let me know. Cheers.
