You'd probably be better with a GPS loaded with charts for your area.
A fish finder/echo sounder will tell you what's underneath the boat - which may be too late if you're sat on top of a rock!

a small GPS plotter would fit the bill

I suppose it depends on your cruising grounds, a GPS won't help with sand bars/spits that are prone to moving.

Yep never thought of that ..I just thought that all round seeing he wasn't a fisherman the plotter would give him more.

I agree that a chart plotter is the must.
But a transom mount skimmer will give you the depth and temperature. I use a Navico (Simrad nss7) and the Navico Transom Mount Skimmer Transducer works well and it's very inexpensive. It's not a fisherman's transducer and will not show the bottom profile or fish.

We also have a smaller Raymarine Gradonfly 6 inch on our smaller rib and it is a GPS and Sonar combo, no touch screen, and works very well on the rib.

How good is the downvision on this in reality? I'm always suspicious of the marketing videos.

Ive used Lowrance units for years and love them, I believe the latest units have electronic compasses built in which is a great feature for pinpointing and always having the screen showing the direction you are facing (even while reversing). If searching for sunken boats or finding good snorkel and diving reef down and side scan are extremely usefull, in shallow water you can locate even small objects such as a bottle (if you ever need to search for a bottle!!).

Heres a couple of images from my hds 8.



side scan with a humpback.


down scan + standard 200htz

Dragonfly works great as a downscan sonar . The border between sand/ clay and rocks /coral is seen clear and you can see the structures, although I have never seen very detailed scans of the wrecks myself. I have seen structures, wrecks, mooring anchors and chain, but nothing as detailed as in the brochures.

I mostly use downscan to find parches of sand and clay for anchoring in inshore areas where the water is not transparent enough.
