Mike Fox Posted October 28, 2007 Report Share Posted October 28, 2007 (edited) I bought this unit in late Spring 2007, selected as a compact combined plotter and sounder, which was needed for the restricted space on my cockpit binnacle. This unit has a 5 Edited October 28, 2007 by Mike Fox Quote Link to comment Share on other sites More sharing options...
Member Removed Posted November 18, 2007 Report Share Posted November 18, 2007 Nice review there Mike, do you have any problems at losing the bottom signal at speed, using plasticine sounds like a damn good idea, would you say the unit is reliable at showing fish? I have the 250c and just don't have any confidence at all in it's fish finding capabilities. Cheers Sean Quote Link to comment Share on other sites More sharing options...
Mike Fox Posted November 18, 2007 Author Report Share Posted November 18, 2007 Hi Sean, Speed for me means 6 knots, as I fish from a yacht, but I never lose the bottom signal, unless going over a prop-wash. I find that fish finding is better at lower speed still, because the echos are small, and I suspect a fleeting return isn't "translated" as a fish very effectively at higher speed. I've seen some units such as Navmans that indicate fish at higher speeds, but that might also be a characteristic of better hull bonding. Perhaps some others on here could advise? It does show fish echos from over 200' down, as I proved on cross-channel trips this summer. The plasticine means that the transducer does lose a little in single strength and clarity, but it's a good temporary measure until I decide if (and where) I should bond it into the hull.

great white Posted November 18, 2007 Report Share Posted November 18, 2007 Nice report thanks Mike Sorry but the speed question cheered me up on a day when the weather has kept me from fishing on the new toy I fitted the transducer yesterday on a layer of blue tac, which I did last time and it lasted for months, i t seems OK while I decide where the perminent position will be and I had a bottom picture at over 15 knots in the harbour, once its bonded to the hull or fitted in an oil bath I expect to get that at ove 20 knots Charlie Quote Link to comment Share on other sites More sharing options...
Member Removed Posted November 18, 2007 Report Share Posted November 18, 2007 Maybe my problem is adding another 20knts to your 6, did try bonding with araldite but I lost some strength in signal so went back to the transom mount, thing that bugs me most is it not showing fish arches when you know fine well there are fish around on the drift.

shytalk Posted November 18, 2007 Report Share Posted November 18, 2007 the last one i fitted went in the keel of a southcat on a bed of silicon sealant the pictures still good at 20kts Quote Link to comment Share on other sites More sharing options...
Maverick Martin Posted November 18, 2007 Report Share Posted November 18, 2007 My raymarine DS600 is fitted in the proper tube with cooking oil and it works a treat through all speed ranges up to 30 knots. It does ocasionally go silly at slower speeds which is just when you realy need it Not sure what causes it but I guess turbulence from underwater structures?

great white Posted November 19, 2007 Report Share Posted November 19, 2007 Martin that is probably the power bouncing the signal up and down fast several times in shallow water If you can reduce the power it should help when sneaking in the shallows for the flounders or back to base Charlie Quote Link to comment Share on other sites More sharing options...
Maverick Martin Posted November 19, 2007 Report Share Posted November 19, 2007 It sometimes does it when offshore in 150' plus but soon finds itself again so not to much of a problem Quote Link to comment Share on other sites More sharing options...
