We use SPOT TRACE and I would recommend it.
- It cost us $50 for the unit when we bought it on
sale, regular
price is $100.
-
Service is $10 per month or $100 per year.
- It updates every 5 minutes.
- It goes to sleep if your
boat is not moving and wakes up when moving again.
- It has an Android app to track your vessel. I *think* there's an
iPhone version too, but not certain.
- They have an online map which shows the data for the past week.
- They have a raw data feed to grab the data for building your own app.
I built an app on my website that saves all the data from my unit. If you want to see what can be done, check out
Displaying our course on Google Maps
Note: initially my unit's sensitivity settings were too low for the sheltered
Bahamas waters so it wasn't waking up for a half hour or more. After talking with their excellent
service department they showed me how to adjust the sensitivity and it works perfectly now. All I needed to do was download a program, connect the unit to my
laptop, and set the new settings.
If you want to see how accurate the unit is, do the following:
Zoom in near Freeport/Port Lucaya. Just outside the harbour are 5 anchors where we stopped and anchored. Zoom in all the way on the one with the mustard-yellow line. In the top left corner of your
screen, click on "Satellite" view.
