GPS units

I have purchased a Garmin 160 C fish finder. the purpose of this was due to the fact i enjoy a bit of fishing and it will double up as a depth sounder which i desperately required. My plan is to purchase a GPS which I hope to wire into into the fish finder and VHF. However I have no idea about electronics. I dont think there is any need for a chartplotter, I just want to be able to plot my way points and log points of interest like wrecks etc. Can anyone advice a good unit that can do these things or advice what i need!

Is there an interface for a fishfinder & GPS????????? I know when we have been diving most just use each independently.

I am unsure, i have been led to believe that the fishfinder can connect to the gps in order to log fishing spots etc. I think i need to contact an expert on this like i say I am like a fish out of water when it comes to electronics

Has a NMEA interface so can be connected to any other NMEA unit such as GPS.

Why do you need to connect the GPS to the fishfinder? Entering waypoints to note points of interest is easy on all GPS and chartplotters. The Garmin GPS 72 is a good basic handheld GPS for about £100. I have one of these but have also boughts a Garmin GPS Map 66CX handheld which has charts on board ( I paid £192 including chart but this was a good deal, best at present is about £240 including chart.. I am thus able to check my position accurately with reference to obstructions wothout transfering to paper charts with the prospect of error. Advantage of handheld is that you can take it home and transfer your waypoints tracks etc to your computer and of course vice versa. If you get your chart on CD then you can also see the chart on your computer. The other advantage of the handheld is that although on the boat you can connect it to your main power supply and interface it thorugh NMEA to your radio, if you should loose boat electricity then the handheld's internal batteries take over independently for backup. the connection to the boat poer supply and the rdaio is done with a Garmin power/data cable. I have a Garmin Fishfinder and see no need to link it to the NMEA even if I could which I am not sure about. the only other device I have connected the NMEA to is the tiller pilot so that the GPS can control the tiller automatically. If you want more info ask.

Thats Makes lots of sense Norman I think i was a little confused the NMEA conection allows me to connect the same sona sensor to the GPS as the Fishfinder. But like you say it will just double the information I have on the fishfinder i.e depth water temp etc. The point you have made there actually sway me back towards hand held. Thanks for the info!
