The reason there are so many Ruger upgrades is because they're necessary.
Forget the bear spray, use wasp killer. Concentrated delivery stream, 10X the product, and only $3.00 on sale.
Go with a lowrance HDS platformI picked up a hds5 naughtic insight for around 500, it was a reman, but it has the nmea2000 interface, plug n play capability, and a whole list of goodies you can buy later, like 4g satellite weather, radar, radar/weather/chart plotter overlay, side scan sonar, underwater imaging, plus you can flip between screens whether it's engine data, charts, split screen, and an amazing sonar. Just make sure to get the right transducer. You can also get multiple units. For example, get the gps/sonar/plotter combo unit, then get the cheaper sonar only model, and use it as a monitor, and run multiple units so you can have one doing full screen sonar, and then the other, run your engine gauges and bottom contour charts. Plus, they are AMAZING on power consumptionI forgot to say even the best unit will run like crap if you don't have the right transducer, I can't stress that enough. Do your research
