Bigger coil with coil-cover

[the Swede]

I am looking for an underwater detector that I will be able to change from the standard coil (e.g. 8-10 inches) to a larger coil, preferably one of size 14-16 inches.

I would also like to get a coil-cover for this larger coil.

Any suggestions on what type of underwater detector and coil that will allow this change/equipment?

Garrett Infinium has 5 coils, all but the 8" round mono coil have covers. The detector is a PI machine. It is good for 200'
Underwater headphones are extra. It comes with a 10x14 DD coil a mono is optional along with a 8" round.
The other two coils are OK for shallow water (10') and are DD and measure 3x7 and 5x10. I have been using one for salt water over the past 6 years and love it.
It is not the smoothest, most stable machine but it has been great for me - once I learned how to get the most out of it, as with any detector.
Both the headphone and coils are user changeable.

There are other detectors available, but not knowing your exact needs...I have offered up this one for you to look at.
