Which range fits what you hunt
Two groups, sorted by the facts that decide them: how much of the detector goes underwater, the technology, and the weight.
Coins, relics and jewelry
The Delta 4000 and Omega 8500 share one purpose list: general purpose, coin shooting, relic hunting and jewelry. They sit close on frequency, 7.8 and 7.69 kHz, and differ on coil size, 8 against 10 inches. Both take a battery listed as 1 x 9 V (not included).
- Delta 40007.8 kHz · 2.6 lb
- Omega 85007.69 kHz · 2.5 lb
Gold and all-round
The T2 runs 13 kHz, and its maker lists it for general purpose, coin shooting, relic hunting, jewelry and gold prospecting. It shows a 1 to 99 target ID on a large LCD. Its page gives no weight, coil or battery.
- T213 kHz

Frequencies across the range
Each line marks the frequencies Teknetics publishes for a model. Further right means a higher frequency, which favors small and low-conductive targets such as gold.
