Hello,

I search 2 devices. I already try 2 tracker but the result is not really good ...

Two need :

1. GPS Tracker with 12V
   Internal GPS & GPRS antenna
   Small battery to keep GPS Signal
   Compatibility with Traccar
   My Own SIM Card
   1 position per 20 secondes, if possible 1 upload per 60 secondes
   Quickly capture the GPS signal : <30 Sec
   Very good Quality
   SD Card to store position if no network

2. GPS Tracker with long life battery
   Internal GPS & GPRS antenna
   The biggest battery, i need 1 or 2 month without charge
   Compatibility with Traccar
   My Own SIM Card
   Waterproof
   1 position per 20 secondes, if possible 1 upload per 60 secondes
   Quickly capture the GPS signal : <30 Sec
   Very good Quality
   SD Card to store position if no network

Thanks for your help, it's very difficult to find the good product, i don't really want to test everyone ;)

So, what do you mean by results are not really good? Any specific problems or missing features?

Sometimes, i lost the position during 3 minutes
Or too long to have a good signal GPS, sometime have the signal, sometime never have the signal (Weather good, nothing around or metal)

I need to be sure to have a good record everytime

Yes, it sounds like device quality issues. Probably issues with antenna(s).

Yes, so i search the same features, but with a better quality.
Maybe internal antenna is a bad idea ?

External GPS antenna would definitely give you better results in terms of GPS fix time and accuracy, but installation process is a bit more complicated.

Unfortunately I can't recommend any specific brands/models. Maybe someone else can suggest you some good options.
